There does not seem to be ANY app or implementation of a parametric equalizer for ANY device.
Whether it is something that uses the hardware parametric EQ present on some DAC's, something that does it in software, be it the audio player or a system-wide app like the way dspmanager works, where is the parametric EQ?
Sure it may be a challenge to control the hardware properly, but every media player has a fixed-band equalizer. It is not much more work to make it fully parametric.
The early iPods had enough capability to run a 5 band parametric with Rockbox firmware. Many users get these powerful phones in order to be able to stream music, and have it sound right.
Is there ANY app for ANY phone that can correct frequency response precisely?
Search for astro player nova. It's got a 5 band.

Moving to Q&A
Sorry, thank you.
Is there one that works globally, as DSP Manager does, but parametric? If it doesn't appear within a month I am undertaking my first Android project...
A computer replacement (Just snickered imagining someone using the HDMI out with a USB keyboard and mouse into the charging port) without a parametric eq is a car without a stereo.
Well Astro Player and Astro Player Nova both have 18 band, but no parametric.
Come on, it HAS to exist. Even a little private project somewhere.

Did you ever find one or make one?
I agree
Too old post, but I googled it searching about this...
There is too many opinions at forum from "audiophile" aboutapps like dsp manager, v4a or any other eq, but some times thats make not complete result or has no result directly.
In my opinion the most direct way from file to hardware, the best audio quality we make. But at the same time the most common headphones/earphones has poor frequency response/sensibility to enjoy our music and need a little frequency correction and some dynamics compression maybe, for some music genres or movie's audio.
This is where I would like to have a simple linear phase sound processor, with at most 3 bell parametric bands, one for bass boost, one for put in mid/high range for attenuate certain resonant peak (particularly in common earphones 4 a 6 kHz freq response is awfully bad), and one more for trebles. And a dynamic comp to prevent eq result overflow and boost low level sounds. No MORE
sorry my poor English.

Many of you included myself complain about stock music player. It has uncountable problems but as far as I know it is the only player which can use the built in high end DAC. The most annoying thing is that it plays song in alphabetic order if files appear at all and secondly it is very slow.
I would suggest a temporary solution what I did and it works perfectly so far.
Delete all playlist (m3u, cue etc.).
Remove a metadata from files too.
Remove all songs with metadata from the phone!!!
Delete all record from "My Playlist" in the initial screen. (I was able to do it just one by one)
Reset Music Player by deleting cache and data in Application Settings
Reboot phone
Then open Music Player and play songs from Folder option. It will be enough fast and all songs appear and in filename order.
In order to remove metadata from files I would suggest using Mp3tag
http://www.mp3tag.de/en/
If you collect your files in any structure on the PC, all you can do is to move root folder into Mp3tag screen, select all songs and remove tags by right clicking. Then you can copy files to phone.
!!! Be careful !!!
Don't remove tags from your archive music folder. You cannot undo. Always create temporary folder and copy wishing music files there in order to remove metadata (tags).
Good lock!

unless your device somehow is capable of utilizing magic to process and output audio there's nothing but the only active DAC to do this task, which you can set in your audio settings.

Ok I was not so precize. Other players don't use AKM dac directly. They do it just via Android which convert all audio input to 48/16 output. Let me know if I am wrong but justify it with something please. Of course then this stream goes to AKM DAC but this not the way we wish it. I welcome any non stock player which can drive dac directly in same way as stock one does. Sooner or later it will be available hopefully but now I don't know any.
If the "Headset HiFi" control in Settings is to switch between SD820 and AKM DACs, then I'm able to use the AKM DAC with other media players that pass audio processing/decoding to the OS (as opposed to fancier players that utilize their own built-in decoding methods/codecs). In my music player of choice (Clean Music), I can switch between the two "Headset HiFi" options (Standard & Super) in the middle of a song and, after a pause to transition, hear a difference between them.

I have bad news which is good news actually. SD820 DAC is not used in A7 at all. There are two additional DACs and one ADC. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". This later is what you turn on when set "Headset HiFi" option. So SD820 ADC/DAC don't play at all.
http://www.androidauthority.com/taking-audio-next-level-zte-axon-7-706898/
and same is on ZTE site as well.
I have doubts that you can hear the difference between the two AKM chips while you don't between Clean Player and the built in ZTE player. Although I don't listen 4961 but I do Clean Player. The difference is significant especially if record is 44.1 kHz because conversion of it to 48 kHz is more difficult than of 96kHz record.

Actually, the SD820 DAC is used and enabled. People with fancy players like PowerAmp (the latest alpha) report that in the app's settings, the only DAC that shows up in the list is the SD820 DAC. No AKM DAC listed.
I'm not an audiophile or anything, but when I have Super selected, the audio has a little more of a "punch" to it, while Standard I can kinda hear a bit of a ceiling. (this is all without ATMOS, of course)

SD820 in Poweramp: I cannot say anything pro or contra. I try to be smart from commercial b...ts. I don't know any well detailed technical quide. Based on these as engineer I would say that SD820 DAC is not used at all. Phone reports SD820 DAC for third party softwares due to compatibility reason but in real AKM chips works. Like I said I don't know it surly but most likely. I am also searching for the correct answer.
I believe that you hear the difference especialy if PowerAmp turns SD820 on somehow.
Otherwise the two AKM chips are different therefore they should sound differently. To hear it is just question of headphone price. Of course it is without ATMOS.
guess we need @rikin93 to use his contacts to get a definitive answer

No. It is justify my concern rather.
"Expressed in Hz, the sample rate in an AudioFormat instance expresses the number of audio samples for each channel per second in the content you are playing or recording. It is not the sample rate at which content is rendered or produced. For instance a sound at a media sample rate of 8000Hz can be played on a device operating at a sample rate of 48000Hz; the sample rate conversion is automatically handled by the platform, it will not play at 6x speed."

you missed the important part:
As of API M, sample rates up to 192kHz are supported for AudioRecord and AudioTrack, with sample rate conversion performed as needed. To improve efficiency and avoid lossy conversions, it is recommended to match the sample rate for AudioRecord and AudioTrack to the endpoint device sample rate, and limit the sample rate to no more than 48kHz unless there are special device capabilities that warrant a higher rate.

which means that it can be programmed to output at 192 khz, but 48 khz should be the default value if there's no additional hardware.
or am i just misinterpreting this whole paragraph?
so either no player can play at 192 khz, or every player plays at 192 khz

Yes, someting like that. Since it is Androud part it is 48 kHz. I used Clean player as altarnative and I prove that there is difference between this and stock.
So as I understand it says that every source is converted to 48kHz and this is sent to dac. You can play 44.1 or 192 kHz source it doesn't matter streams will be converted to 48. Stock player alone can bypass it so far. And it is important in case of CDs as well becuase 44.1 to 48 conversion is the one of the ugliest thing can happen here.

i just tested listening to some flacs in my regular player, vlc player and the zte player with my beyerdynamic custom one pro. either all of them were outputting the same format, or i am just not able to hear the difference.

So I am not fan of VLC Player therefore it is not installed on my phone. May be I felt wrongly and there is no difference because it doesn't exist at all and every player drives DAC appropriately. All I know is that I listened music by Clean Music for weeks and than I exchanged to ZTE player. Going through the music repertoire I was surprised. Anyway I am human too.
After all the fact is that you didn't here difference proves only one thing, namely you cannot hear the difference. Here and now.
I will study developer link what you suggested more thoroughly and also I am still waiting for the correct technical details from Android experts. Until I use ZTE player which works fine in above mentioned way. All song appears, all in order, no lag and sound brilliant. What else is needed?
Music Player DAC issue **Fixed**
Hi, I have a fix to using the DAC on non-stock music apps.
So I received my Axon yesterday.
Ipgraded from the Lenovo Vibe X3. I first ran in on the DAC problem on the X3.
In my experience all of these dedicated DAC phones follow the same approach, i.e., LG V10, Vivo Xplay 5, Vibe X3, Axon 7, and (I as sum) LG V20 as well.
There is already a thread on XDA explaining this in detail. -> http://forum.xda-developers.com/lg-v10/general/music-apps-using-dac-t3252596
In short, the apps listed on the V10 page will use the DAC. Although the Vibe X3 had a dedicated DAC toggle, and the Axon 7 doesn't.
To test whether the DAC is being used by a music app on the Axon 7 is:
1. Plugin high fidelity headphones (so you will be able to hear and verify the difference in music), if you can do it with regular earphones/headphones, good for you. and kickass hearing btw
2. Play music on the music app you want to test. (Refer the LG link I posted)
3. while the music s running in the background, go to Settings -> Sounds & Vibration -> Headset Hi-Fi -> and switch between Standard & Super settings.
IF that app is using the DAC, you'll notice a slight pause (when the DAC switches on/off) and of course the difference in sound quality.
Note: Switch Dolby off or ignore it when testing the app, cos for some reason switching Dolby Atmos on/off produces the same gap in playback as the DAC.
On the Vibe X3 it didn't.
I used to use PowerAmp earlier, cos I found that best for my taste.
Then I discovered Neutron, and fell in love with that.
However then I bought a DAC phone & both Power-amp & Neutron don't use the DAC(or I wasn't able to make them)
As per a lot of users online "Poweramp Alpha" can be made to use the DAC on such phones, somehow. I tried fiddling around with it, got fed-up & left it.
If someone has the patience to figure it out AND explain it to me, I'd be grateful, cos Poweramp is my player of choice in terms of UI & ease of usability.
Neutrons latest changelogs mention it can use DAC usage as an update. But I can't notice the difference in the method listed above, or maybe its referring to USB DACs.
Now my player of choice adter going through the list of DAC supported music apps is Pulsar. - https://play.google.com/store/apps/details?id=com.rhmsoft.pulsar
Reason being, I found it to be the lightest/cleanest player which supports the DAC and can relatively smoothly handle my 10K+ collection of 320kbps MP3 & FLAC collection.
You guys can go through the list of apps on the LG V10 page and decide. which suits you best.
h/t @stupc. I've found his thread to be the most informative and bang on in solving the problem of 3rd party DAC phones throughout the net. And trust me, I've searched. Went crazy trying to solve this when I first bought the X3
Hope this helps.
Mods: Please move the post/thread to the appropriate section if required and close the thread as solved.
Hit Thanks if this helped.

thank you for your answer.
the method to check whether the seperate DAC is being used supports my observation, that i wasnt able to hear a difference between all 3 players i've used.
but i guess the question remains whether the output is in 48khz or 192khz for all of them :/
I'm sceptical about the differing sound quality when switching the "Headset HiFi" setting. I noticed that the volume increases significantly when the setting is on, and goes quieter when switched off. This is a well known and proven psychological sales tactic for audio. The human brain subconsciously associates louder sound to be of higher quality.
In this case it would be very difficult to perfectly volume match the on/off setting of the "Headset HiFi" toggle for a proper blind test. I don't believe any user testing can be trusted unless it's done blind, as confirmation bias could easily take precedence.
Some good reading:
https://en.m.wikipedia.org/wiki/Psychoacoustics
EDIT: I just did some more rudimentary testing with consumer quality mp3s and the ZTE music app, toggling the Headset HiFi setting on/off. The difference in frequency response is very noticeable even when not using high end FLAC encodings. There are significant bumps in bass and treble, even when compared to other sources I have with known flat sound signatures.
So you're asking, what does this mean? There's two scenarios:
1) if the Headset HiFi toggle is indeed switching between the Axon high end DAC and the SD820 standard DAC, the Axon DAC is far from neutral and has a coloured sound with unnaturally increased bass and treble response. This is arguably positive for the average consumer who likes the visceral sensation of an unnatural U-shaped equalizer, but will be disappointing for audiophiles looking for a flat sound signature.
2) the second possibility is that the Headset HiFi toggle does not change which DAC the system is using, but rather is like a Loudness button found on many stereos. When volume decreases, the human ear perceives low and high frequencies dropping off faster than other mid range ones. Loudness buttons are added to stereos so that low volume listening frequency response sounds closer to what the ear perceives at higher volumes.
Yes, Max has finally released a test build (790) to replace 704 so those who like it, log in, download and test away. Read the first page for notes and assess any bugs. I have installed it but at work so no chance to use it yet.
http://forum.powerampapp.com/topic/...te-read-first-post-before-commenting/?page=20
Remember you MUST have a Poweramp forum account and log in to get the download.
I usually use Jet Audio HD but got a bug where it doesn't allow Tom Tom navigation to override audio focus for voice prompts so at present using Player Pro as my daily driver. Here We Go navigation works ok with Jet and Player Pro works fine with either so there's something funny between Tom Tom and Jet.
I hope the new Poweramp works ok, there are bugs and missing features so I will keep the others installed and assess Poweramp as Max addresses the bugs and rolls out more features.
Edit: Having a play with it at work, boss has left for the afternoon.
Whilst my work BT speaker (Jawbone Big Jambox) aux in is connected to my Axon 7 by wire and I played with output settings in Poweramp, set to use Audio Track, I get a marked difference in speaker volume output when switching between Headset HiFi Standard and Super in the phone audio settings. This is working better than before. I'm only on MP3 though so harder to assess as the files are not Hi Res but if I set the Big Jambox to max volume and the phone to max volume then switch from Standard to Super it's much louder and does sound better. That Jambox really cranks on this! It will overload the aux in and I have to set it back two notches so seems to be playing at too high a voltage for the Jambox input jack. Need to play with this some more. Will have a listen on my Backbeat Pro headphones tonight and also in the car on it's HiFi as that has a great dynamic range and quality with BT and wire.
Install it as a secondary player due to missing features. Max the dev will be adding stuff as things progress but I find it not quite fully functional enough to call a daily driver. I feel it's less bugs, more just not all features added and expect as he hears feedback will slowly add them in.
Here's my test setup. Dedicated page aside of my home screens with app shortcuts and widgets for easy comarison listening.
Got it yesterday. Sound-wise, it's solid. Audio flinger reports proper playback at the selected sample rate.
I had some issues with the volume whenever I got a notification even with "Audio ducking" and "short notification interuption" disabled. The volume drops, but never comes back up. I've seen on the PA forum that disabling "Float32" in the OpenSL HD settings (even if you're using Hi-Res output) fixes it. Haven't tested this yet, though. Will do it when I've got my IEMs with me.
Other than that and the obvious UI bugs, it's a good step forward, despite taking 2 years to do it.
Interestingly, the actual volume control behavior was fine on my phone. I have issues with Jet Audio though. It doesn't mesh with Tom Tom navigation app voice prompts. Got fed up with that despite the rest of it working well and great sound and have been using Player Pro for a while. It behaves reliably and now adjusted, sounds great too. Both Jet and Player Pro sound better than Poweramp for me. I have PP set as default player and is on auto start up.
I emailed Jet Audio and Tom Tom about my issue. Tom Tom have been in contact. Nothing at all from Jet. I'll probably end up uninstalling Jet.
I tested this briefly, to say it's a beta preview is an over exaggeration. It's an alpha and is way more alpha than 704. I use Poweramp near everyday and love it but I tried testing 790 but there is so much missing functionality it is just no good for a daily driver. Shame both couldn't exist on the same device, I wouldn't mind testing it then!
TBF I thought that max would have been further on with its development after the time it has taken. I know he is working on this by himself so kudos to the guy but it is so unfinished, for me, it's back to stable 704. I will try again in May with the next test build.
Sent from my ZTE A2017 using Tapatalk
Yeah, so much functionality missing, I still have it installed but it just doesn't sound as good as Jet or Player Pro for me so the point of having it at all is questionable. Max took so long to get this far with it that others have risen to the top instead.
It reminded me of Neutron a little. You have to really fiddle with it to get good sound. With Player Pro the settings are simpler but just what I need and the good sound is there. Pity the skins are ugly.
With Poweramp, I don't like the wavebar and no skip buttons. The widget wasn't fully functional etc, just not enough I liked in it for a 2 year wait. Will uninstall. See how it goes once worked on further.
Just from curiosity I had a listen with VLC. I have it for video. On wired output it's not great but did sound very nice on my backbeat pro 2 headhones over bluetooth. Not a good audio player though.
After a few days with Poweramp and finally making the jump from Nougat to Oreo, I'll have to agree. It's more alpha than the previous alpha. I lost the Hi Res option after installing AEX 5.4. Quite disappointing but it's expected. To me, anyways.
I'll keep an eye on development but I'll be using UAPP for now. Simple UI, Hi Res works great and it sounds awesome. Hopefully Max is able to refine and polish PA in less time it took him to make it.
I had another play with it last night, found that just need to route everything through HD off the QC SoC. I mostly use bluetooth these days so 24 bit off the SD820 is fine. I could lose the DAC finally and not really worry but not ready to give up the 3.5 jack though..... Sometimes it's handy.
I had 2 Poweramp widgets on an extra homescreen and couldn't remove them. Had to uninstall the app to get rid of them. Too much broken functionality but with polish I think it will be good overall.
Edit: I'd like to know how the AKG DAC is implemented in this phone. It's almost as if it routes through the DAC if using HD and Super is enabled so it may not matter what the music thinks as long as it uses hi res?
The more I use new Poweramp the better I like it. Makes me want the missing functions implemented. Definitely not giving up on Poweramp.

Hi-res never worked. Now it's the same as before, it'll tell you it's working but it's not (it's written though, hi-res doesn't work in Oreo).

I didn't get anything of what you said here, but i'll tell you what i know:
-poweramp won't output hi-res in Oreo, and it will happily tell you that it is - hence, you have to use dumpsys media.audio_flinger as always
-What do you gain by routing everyrthig through the low power DAC? (Again, ZTE said it's a DAC inside the AK4961, not SD820). I wonder if that DAC actually works with 24-bit, but at least it is specced that way.
-What do you mean by the last paragraph? The DAC will output whatever kind of sound you input it, it won't "only" play hi-res.
Btw it's AKM, AKG is a headphone manufacturer
Other thing: Disable hi-res output. Use the normal OpenSL output. That way it'll sound just like good olde Poweramp
If I go back to OpenSL it sounds markedly inferior.
I keep mixing up AKG and AKM lol.
What I meant was if I have the phone set to output on Super setting and the music app is using Hi Res it does seem to sound louder and better in general, as if the phone just puts it through the AKM DAC anyway, despite the app thinking it's using the SD820. With Poweramp 790 alpha the phone will still overload the input on my car hifi when at full volume so it seems it's using the DAC, not the SoC.

As in the output setting is completely gone after jumping to Oreo. I did get the Hi Res on 704 to work when I was on 7.1.2 using either the samsung uhqa cheat or lenovo hifi cheat. It wasn't true hi res, but there were differences when I swapped between the sample rates. So it still "worked" in a way.
790's hi res worked on 7.1.2 but it looked like it was detecting the qualcomm DAC and not the AKM. I might have to resend the hi res request in the Poweramp forum.

In my case (8.0.0) it is there. Sound is worse with it turned on though (much lower volume basically)

Do you have volume issues with other players? Because ever since I installed Oreo 8.1, the volume's dropped quite significantly across the whole phone. UAPP and Poweramp play at really low volume now. Could be an Oreo thing or an Ainur thing. I'm not sure.

I think it is an Oreo thing. As soon as I went from RR-N to RR-O I noticed my headphone volume dropped significantly. I'd love to know the solution
What do people recommend for HD audio using the DAC? I'm using the RR remix ROM and have Viper installed. I guess Play Music uses the DAC? I've only ever used Poweramp

USB Player Pro. In one of their recent updates, they added support for DAC chips on phones. Axon 7 included.

Nope, that's most definitely an Ainur thing. If you installed Poweramp beta, be sure to disable OpenSL ES HD output (supposedly hi-res) because that will lower the volume quite a lot.
Also install the B32+B10 bootloader if possible. That one seems to have fixes for audio.
In stock Nougat it's fine. I turned volume to max and switched between. The volume steps are different but max is fine. I found it sounded better with Float32 switched on.

No way, the first and only time I tried USB Player Pro it literally killed my SD Card (I don't understand how)
I've been trawling Google Play and revisiting music apps. It seems Onkyo HF Player has had a bit of a revamp. It's getting quite good now. It has widget and notification functions etc. Still no auto start though. One thing I like is it shows the output in now playing. With my backbeat pro 2 cans in wired mode and turned off the app is playing a 44.1KHz MP3 and upsampling to output at 48K. If I go into phone sound settings and turn on Dolby Atmos then go to the headphone setting and switch between standard and super there's no difference. If I turn off Atmos and switch from standard to super it gets louder and soundstage expands. Interesting....
It still has that great user configurable parametric EQ too
Playing a hi res WAV or FLAC also shows on screen. I assume the Axon 7 won't output above 48K though? I suspect this is running off the SD820.
So if it plays above 192K what does it signify? Nothing?
Or the DAC?
There's a Nougat Dolby port confirmed working on 8.1 ROMs. Thanks to @roisuke guide (and permission to repost for info) on the LOS15.1 thread summarising steps similar to the original Pixel 2XL guide, which uses the old ARISE N Dolby Atmos zip. In roisuke's post, his/her reason for trying this old Dolby is the newer Dolby boot loops on LOS15.1. In my case I was looking for a better compatible and audio quality Dolby when I found out about it. There's a few reasons i'll group into headings below. I know Dolby speakers that we paid for on stock for our device is a loved feature sought by more than just a few of us. I hope to help improve some people's speaker audio experience like I have, finally rivaling stock performance with V4A extra on top :laugh:
For installation instructions I'll just link roisuke's post, as mine has more to do with settings and usage explanation. I will just add that I had a different issue installing that Dolby zip on RR-O, the process would freeze without an error, requiring a force restart. The zip isn't detected by Magisk Manager and so can't be installed there. I couldn't install the zip when any Magisk version is installed. I ended up having to uninstall Magisk to allow the zip to install to system and then follow up with the other Magisk audio mods installed normally, Viper4Android (i'm on the old 2.3.4.0 for it's Super driver and better graphic equaliser), Ainur Sauron (optional maybe, it claims to improve audio in system and targets Axon 7 as well, I haven't tested this mod without it yet) and lastly Audio Media Library. Also thanks to @Oki for pointing out the hifi DAC patch is necessary with this particular Dolby mod.
Nougat Dolby sounds better
The reasoning is that I've recently been testing custom ROM N Dolby and it sounds just as good as stock N had. While I tested Oreo Dolby ports back when the B32+B10 bootstack was new also just recently too and found it didn't sound as good as N's. Therefore I understand it's not a custom port issue that the new O Dolby sounds worse than N but that it's the updated Dolby itself.
It can work together with V4A
A benefit of this old N Dolby is it is working with current V4A whereas I can't seem to get the new O Dolby to run with V4A, it did when I tested months ago but I can't recreate that either. A benefit to using V4A in combination is it's "Firequalizer" to preset "Small Speakers" accentuates bass and lessens the tinny treble, this is something I used to do back on stock N as well.
It can be configured to set and forget
A little talked about but great feature of stock Dolby is it remembered the settings separately for plugged/unplugged and for each individual app last playing audio too. That made it so good being only on for internal speakers as I preferred and would change settings mode automatically when you stopped audio and started in another app.
Custom ROMs with Dolby ports doesn't remember states, however with a bit of compromise it can be used as such on this N Dolby if you prefer Dolby to only affect internal speakers. The trick is to set no extra filters and EQ in Dolby but just have Dolby enabled. With all other settings off, it still positively affects speaker audio but has no affect on headphone jack audio, you can test this by listening either way while switching on and off. This works combined with the V4A equaliser settings as previously explained. Set rather simply as so, the speaker output has less harsh treble and increased bass to sound similar in presentation to listening on quality headphones.
Extra notes
A shortcoming bug with this N Dolby port however is the Surround Virtualisation feature doesn't work on speakers. It seems reversed and only works when plugged in, I find it best to leave it off as preferred and it will stay off. This bug is unfortunate as the surround was always nice in my opinion, but it's only one loss compared to all the other gains. For what it's worth I couldn't audibly hear a benefit of the surround feature on the O port in my limited testing. Also consider if using the O port where the effects are all somewhat changed for worse in my opinion, it also has to be manually switched off afterwards to not affect plugged audio unlike with the workaround available in the N port. In terms of comparing missing new features, the Oreo version has a bass boost toggle and a dynamic setting, overall though I couldn't settle on an audio setup I liked with any Oreo Dolby settings.
Conclusion
I hope my experience will help others to finally get the most out of their speakers with Dolby and V4A. Since moving from stock N to custom Oreo in early April left me disappointed in O Dolby quality usage issues, I'd stopped using it and relied only on V4A's Speaker Optimisation setting for improving the speakers as a compromise but it always left me wanting in comparison. However now recently finally figuring all this out, i'll be using this for the forseeable future. I really adore the loud unbeatable quality Dolby speaker output for general listening, I mean even a dozen meters away it sounds transformed like a good dedicated mini speaker is playing. This coming from someone who appreciates listening on premium headphones too.
Nice work ofcourse but i dont agree nougat dolby sounds better. In dolby oreo there is more to adjust also

It depends on your ears (or beliefs) I guess. Regardless if you've preference for O or N's Dolby, there's still good reason to use the N port. Mainly that it's able to be set and forget and also it's working with V4A aiding it too without issue.
So after reading your guide I liked the idea of a "set and forget" approach and chose certain presets for fireequalizer while in headset (bass booster) or speaker (small speakers) modes; also I changed v4a to the older version since I was unaware of its "super driver". However in the Dolby app I chose to leave on the "intelligent eq open" because to my ears the sound came across "fuller" if that makes sense.

I'd recommend Dolby's extra customisations to be off because they remain active when plugged in. Unless of course you like any of its setting for both plugged and speaker. Relying on V4A for separated audio modifications fits well, you could try playing around trying to improve settings there if desired.
I used to prefer Rich in Dolby with Small Speakers in V4A together with Surround Virtualisation. Now with SV unavailable, I assume the EQ effects in Dolby are less pronounced because I can't notice much of positive difference with them on. When the issue being the setting will affect plugged too, it's a small worthwhile loss turning them off for the automated convenience.
Your headset preferences will totally depend on your headphone hardware and listening preferences. From my reading and understanding it's better to only use an EQ to reduce Frequency Response range positive peaks. Never to increase EQ as that introduces artificial noise. I'll attach two screenshots showing my hifi headphones FR graph and the V4A EQ I use to show what I mean (EQ graph doesn't match scale, zoom in to see the tiny DPI X Y values). The green line is the ideal neutral target FR with bass effect for headphones. Note when adjusting V4A's graphic equaliser the range of each frequency band is only shown on the old original 2.3.4.0 version.
Obviously mobile speakers are different in severely lacking bass, accuracy and need the bass EQ boost regardless of accuracy.

@roisuke, It works as expected using Magisk 16.7. I did in another order and it also worked:
1. V2A FX 1.6.9 or later (I've tested old and current versions)
2. Sauron MK II.II 02.05.2018 or later (I've tested old and current versions)
3. BQ-E4 Dolby ATMOS (Dolby-Oreo.zip)
4. AML 1.7 or later (I've tested old and current versions).
I've noticed the flashing order is irrelevant as long as AML is the last one (It is intented to be always the last module to gather all the audio configs). It works with any install option of V2A (I prefer 2.5.0.5 traditional interface).
I believe the flashing of the ARISE module reroutes the audio paths and disables the hifi DAC when the BQ-E4 Dolby ATMOS is installed. I suspect it because the quality is vastly improved only if, at the end, I flash the Mixer_AK4490.zip to restore the HiFi DAC wiring paths.
These are great news since in Oreo I haven't found a way to have DA and V4A together.

I already listed why I prefer 2.3.4.0. I didn't mention in general UI the newer versions hide settings behind presses, makes it harder to use and see for example the selected EQ visual profile.
I was focused on speakers so actually hadn't tested jacked audio expecting it to just continue hifi as always on newer bootstacks. I thought Ainur Sauron is supposed to include the DAC patch as @Skrem339 added Axon 7 mods to it, he's also the author of the AK4490 DAC patch in question.
In any case I gave jacked audio some testing. I immediately found with the DAC patch there's static noise when booting jacked in and charging, but it phased out after replugging power, further testing for this may be necessary. After a few short install uninstall tests audio comparison, quality does sound improved. Thanks for mentioning that detail.
Here's the DAC patch thread with system and systemless. I updated the OP with this detail. Systemless only installs through TWRP still by the way. Small note worth mentioning though maybe unrelated is my fingerprint sensor stopped working after installing the Magisk patch, but worked again after uninstalling and reinstalling (a reset may have been enough).

This patch is useless for Roms based on Android 8 because DAC works on them without patch. Also, this DAC patch was remove from Ainur by my request to Ultra8

For some reason the DAC patch is required after installing the Dolby Atmos patch mentioned in the OP, even in Oreo ROMs.
Hi @Infy_AsiX, can you give a link to the exact Nougat dolby port module which you are using on Oreo together with the 2.3.4.0 v4a? I tried all Oreo versions but they give me bootloop on S8 device, thanks

Well, I havent tried it in a Treble ROM. I don't play games or watch ATMOS movies. For Youtube, music and general audio, Viper4Android provides more features and richness to the sound so I don't use ATMOS at all. For external speakers I only notice more volume and some equalization, and I also have that configured in V4A in the speakers section. Treble roms are tricky. V4A is awesome when used properly.

Do you mind sharing your settings? I used Atmos on dynamic setting in my car with Android Auto and Spotify. Car never sounded better. I'm now on treble with PixelExperience P and stuck with Viper. Sounds ok, but the dynamic system makes the sound go in and out.

Been meaning to ask, @Oki. Your settings above are for headphones, right?
The Axon 7 isn't my daily driver so I don't use headphones with it much as I don't carry it around. Been trying to get some good speaker settings, mostly for locally stored music and occasional streaming video.
On this Nougat ROM Dolby Atmos and Viper 2.6.0.5 are working well together. In AEX 5.4 Oreo the two are also working but not necessarily together. A long time ago someone posted custom FireEQ settings which I still use but the other stuff not too sure about.

Hey all! Just bought the 7.1 from B&H for $349 to replace my Moto g5 plus which is full of issues. One thing I will miss is being able to install V4A (Viper equalizer). I can tune the settings and make my Bluetooth to car connection sound a hell of a lot better than actually changing the settings on the head unit. Was wondering if there was a stock (or built in) EQ for the Nokia 7.1 that I can use to tune Spotify, YouTube, etc. or if I'll have to download a crappy EQ app off of the play store. Is there a built in EQ, or even better, a way to install V4A on this phone without TWRP? Thanks!

There is a way to change the Bluetooth codec in the dev menue, not the same as an EQ but wouldn't you want the signal to transfer as true as possible and use your speaker source EQ?

Yeah I got the phone, saw the stuff in the devs. To answer everyone's question, there is a built in EQ, but you have to open Spotify to use it (not sure if GPM or Pandora work). It's not terrible, but certainly not as good as V4A. And to respond to your question, I don't think the signal transfer is really touched with an EQ. The EQ adds bass and lets me adjust my mids to the way I like them. Like I said, my head unit is garbage. The EQ practically does nothing to improve bass or mids. At first I thought it was the speakers but it isn't. Thats why I wanted a built in EQ on my phone, until I get a new head unit at least.
