[Q] usb dac/usbhost - Asus Eee Pad Transformer Prime

Hey all. I want to use a USB DAC on my prime, I know its not possible on the stock prime, but I would be willing to unlock/root to do it. I've rooted android devices before, but its been a purely "paint by numbers" affair for me. I see people talking about things in the dev threads that go way over my head. Does anyone know a good rom I can use that will give me USBHOST functionality to use a DAC, or failing that could someone somehow customize the ability to do so into the rom?
I am an audiophile, and the primes onboard DAC makes my ears want to bleed and my sr225i's want to melt. And please dont try and tell me to get beats audio, or some other software EQ mod, I'm tired of people being like "HURR DURR GET BEATS AUDIO/DSP AUDIO", while they listen to music on their cheap skullcandy headphones. Sorry, didnt mean to rant. I just really dont want to buy an ifad but it is looking like that is the only option.
Anyway... I just need a stock/bloatware removed rom (a little overclocking wouldent hurt either), with the ability to rock a USB DAC. I tried using the search function but there wasnt really any informative answers out there, which is truely disconcerting. I am really at a loss for what to do here.

So no one has any info on a usb audio enabled rom/kernal? No other audiophiles here? Dissapointing.

It might get support when we are updated to Jellybean. See here:

Equalizer

I searched through here and google, and couldn't find an answer.
Does anyone know if the 2.0 update will have an equalizer? Is it really that hard?
I don't think it have equalizer, they work only for: Contacts and accounts
Email
Messaging
Camera
Android virtual keyboard
Browser
Calendar
Media Framework
Bluetooth
New Framework APIs
I'm very happy that they work for bt Try to find something on the market
i have no idea what carmen2009 is getting at... but as far as I've read, no, it will not. I don't think it would be that difficult to create an app that would control the EQ.
I've been waiting for an equalizer too. I just want to tune the high end pitch note.
For me, the equaliser is probably my only fault with the phone.I've came from an N97 to a Hero, and the media player on that was amazing, drove my headphones perfectly.The Hero still sounds great and drives the phones well, its just that with no EQ, it isn't really a viable as an all in 1 phone/media player/internet device.
Maybe this will help:

Parametric equalizer

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.

[Q] How do I make CM7's Dynamic range compressior from DSP manager work

I'm trying to get dynamic range compression to work for DSP manager. I installed the .apk from CM7 on my Samsung Galaxy YP-G70 running Gingerbread 2.3.5 and all DSP features work except Dynamic Range compression. Does anyone know if it needs to be flashed as part of a ROM to make it work? My device is rooted, however there is no support for it for CM7 yet. I get no responses to this question when I post on the Cyanogen forums, most likely because my Samsung device isn't supported and I'm being ignored.
Yes, yes I know, everybody hates Dynamic range compression, "It's destroying music" blah! blah! blah! But there are many times when it's needed, especially on small devices like android phones and PMP's. Listening to music, movies and video clips on these devices in noisy environments, or on small speakers can be difficult to hear the quieter passages of the content. then of course when the loud parts come in, they blast the speakers or headphones with distortion. I can't believe there aren't any Android apps out there to address this situation. Anybody know of one that maybe isn't on the android marketplace?
Yes, i love "dynamic range compression" too and i wish to use it with YP-G70, but it seems not possible to our device.
All i know because compatibility sound chipset... most of devices which compatible with DSP Manager uses Wolfson audio chip.... unfortunately, YP-G70 uses yamaha audio chip

Parrot Asteroid Smart Bluetooth and Sound Issues

Hey guys, I just replaced a Sony deck with the Smart and I LOVE it so far. It's taking some tweaking to get it how I want it, and to get it to do what I want it to do and why I chose it over Appradio. I have it rooted, and I've got the Play Store working great. The lack of a volume knob is a drag, but I'm hoping to fix that with PullOpenSettings. I have 3 unsolved issues so far:
**1. The Sony deck it replaced had separate HPF/LPF so that it could ensure that only bass went to the subs, and I was also able to remove most of the bass that went to my regular speakers since they don't really handle bass at the volumes I listen to. I see that I can set the crossover frequency for the subs and that's great, but is there an app that will allow me to adjust the bass to the speakers without affecting the sub? I've searched high and low and I've yet to find one.
**2. I cannot get my Bluetooth ELM OBD adapter to pair. I read in an Amazon review that "All I had to do was install the Bluetooth apk and it worked perfectly" I'm not sure what 'Bluetooth apk' he's referring to, but I'd sure like to know!
**3. Lastly, why can't I get this to Bluetooth tether to my Nexus 4 running CM 10.1? Yes, I have Bluetooth tethering enabled in the phone and in the head unit, and dual-mode is off. If you look at each other's profiles on the other, there's Phone Audio and Media Audio, but no profile for PAN. I'd read somewhere that installing Open Garden Wifi Tether would fix this. I didn't see how it could, but I sideloaded it to my phone and of course it didn't work. I just can't figure out how to give the deck PAN.
***Any Help with any of these would be appreciated!! Thank you!

Forcing calls to go through A2DP in Android, while using the phone's built-in microphone.

Hello,
This issue has been driving me insane. It seems like some simple, artificial limitation that no one seems to circumvent. As the title suggests, I'm trying to force phone calls and especially VoiP calls (Discord, whatsapp..etc), to go through the high bitrate A2DP profile instead of the horrible HSP/HFP profile that butchers audio quality and uses the horrible bluetooth microphone.
For instance when music is streamed through a bot in Discord i have to listen to it in horrible earpiece-level phone call quality.
I feel like there's got to be a tweak, a Magisk module, a custom ROM functionality with root access that allow for this, something.. I found a couple old XDA posts about this but no solutions. Oh and also tried Lesser AudioSwitch on multiple Android versions, none worked.
It seems inherent to all bluetooth headphones which is a shame, they could cost 10k $, but the quality would still be sh*t in calls, both in and out, since mic is not close to the mouth.
I always loved Android for giving users more control, but sadly seems like this is more and more going away. What i want here, can very easily be done on PC.
Thank you for your time reading, really hope someone can help.
