HE-AAC v2 decoding sounds bad. Bass distorted. - HTC EVO 3D

Hi there. I'm creating this topic so you can share your experiences with HE-AAC v2 playback on the HTC EVO 3D. As for myself, I hear lots of bass distortion, regardless of volume level on my handset.
What I use: The latest version of WinAMP (for it's free transcoding feature) + WinAMP Essentials Pack (for ALAC decoding)
Source tracks: Apple Lossless audio files @ VBR kbps
Target tracks: HE-AAC v2 @ 56 kbps
The source tracks are authentic CD rips and/or WAV purchases. While the target tracks sound AWESOME on a PC (tested with iTunes v10.5.3), on my headset they are properly decoded (you can hear the full 44khz spectrum) but the bass gets distorted. This is specially noticeable on Dubstep-genre tracks. Does anyone has some experience with this? Alternative player?

Wow... fixed the problem myself. PlayerPRO does the decoding correctly. No bass distortion. Thanks.

mp3 too large!

hello, developers.
is there any way to put mp3's on my device, but change them into a smaller file? convert them to different extention?
You could re-sample them to a lower bitrate (Google: "resampling mp3"), or play them from a large SD-card.
I compress all my Mp3's using X-ing MPEG Encoder (now owned by real).
I use the 64kbs setting with small loss in quality over CDs, but I can fit humongous amounts of MP3's into 64Mb. However I use 128Mb SD cards for more storage and can compress an entire feature film down to 70Mb!!
Windows Media Player 9 will automatically copy and resample files to any portable music device or card. Works great. I resample everything to WMA 64k, get double the space with little quality loss. It does this via playlists, so it is easy to switch your music around.
thanks rustek.
but where did you get this x-ing mpeg encoder?
Hi,
if you have windows media player 8.5 on your xda, then you should be able to play mp3 and wma files.
You can actually get good quality sound out of a compressed wma file, at 64 bit rate or lower
use www.dbpowerAmp.com tool to covert the source file to any bit rate you want. Follow the codec insallation on the website.
i managed to get a 5mb mp3 file, down to a 900k wma file, and it sounded very reasonable on the xda.
For low bitrate WMA is the way to go. Keep your eye's on Windows Media Player for support for MP3pro, this is on par with the WMA encoding rates v quality.
hi all,
does anyone have a cab file of any mp3 player? i left my cable at home so im planning to install it from other PDA.
thanks! :lol:

[Q] which of these audio formats are the best for sound quality?

which of these audio formats are the best for sound quality?
I want to listen to music on my new phone and since i have the storage i would like it to sound as good as possible.
MP3, AAC, AAC+, eAAC+, WAV, MIDI
WAV is the best but the largest in size. Also if you are using the stock ear piece then none of the format will make much difference.
thanks for taking the time to respond.
Much appreciated.
ur welcome. The alternative would be 192mp3 format anything below that sounds crappy to me

Stock ear piece? Headphones? The atrix did not come with headphones

Yes, you are a confuzzled Singaporean.
LOL actually I think they took the whole budget for the whole thing and pretty much put it all towards the phone.

It's not in your list but FLAC is the best one. It is losless (same with the WAV) however still compressed so each CD takes rough a third of the size it takes if it is WAV.
.Flac is the best music format!

MIDI is not for sound recordings, it's for synthesized music. Not comparable to the others.
WAV is perfect quality, but far too large to be usable for a music collection.
Out of the usable ones, the quality is best to worst:
eAAC+, AAC+, AAC, MP3
I'm not sure if everything supports eAAC+ (AKA HE-AACv2) or AAC+ (AKA HE-AACv1), but AAC is fairly widely used these days. I wouldn't bother with MP3, unless your media is already in that format. It's a very old format, and has been improved on several times. It's a legacy codec, not a current standard.
And FLAC is supported by PowerAmp on Android... Probably other music players too.
pity there is no gapless playback yet for flac.

MKV with horrible sound

I just put an MKV movie on my SD card and played it using Dice Player. The picture is perfect but the sound is awful. It's very crackly through the speakers and through headphones. The sound is perfect when I play it on my PC though. Here are the audio specs of the movie:
Audio
ID : 2
Format : AAC
Format/Info : Advanced Audio Codec
Format version : Version 4
Format profile : LC
Format settings, SBR : Yes
Format settings, PS : No
Codec ID : A_AAC
Duration : 1h 50mn
Channel(s) : 6 channels
Channel positions : Front: L C R, Side: L R, LFE
Sampling rate : 48.0 KHz
Video delay : 1s 500ms
Use MX Player. Works great.

I just tried it 2 seconds ago. It's a 1080p mkv and it's very choppy with MX Player.
is the video using hardware acceleration? If so, all the players should be playing the video exactly the same, even the built in video player. As for the sound, you can use something like MX to use software decoding for the sound alone to correct the problem.

Can you explain that in more detail? Are you saying to use Dice for the video and MX for the audio? How would i do that?
The problem is that Dice doesn't downmix AAC 5.1 to 2 channel (but does for AC3), and the LFE is pushing out making that crackling sound. I've emailed the dev, but no reply about it.
It does this with any file that has an audio track of AAC 5.1 no matter what container. I had a rip of Drive with AAC 5.1 and it crackled in Dice but you could skip/seek in the movie, and in other players it played with perfect audio except you couldn't seek in the movie.
If the sound sounds like a dying robot, then its not just the prime, as that happened with my Evo 3d as well.

best audio format for xperia s?

which format are you guys using for music on your xperia s'?
i have all my music backed up in apple lossless or flac, so i can re-convert to any format that's best.
i've currently got most stuff already in ogg at approx 64kbps for my ipod mini.
but sony media go doesn't seem to recognise these files/i can't import them in to the media library.
so i'm thinking of converting things to AAC (M4A) which media go does recognise.
are there any differences in performance/battery life etc between these formats?
and i remember reading somewhere that the built in music app supports gapless playback, is this just for mp3? or also for other formats like ogg and m4a?
im normaly use MP3... but its not a question of belive in this format, ist just because the most files im download (legal) are in mp3 320kb/sec
Ogg 64kbps is horrible .
A song should be at least in mp3 128kbps with decent encoder .
been using ogg at 64 for a while now, it's perfectly listenable on a portable device, and have managed to reduce my music collection down to around 10Gb by using it
was just curious to see if anyone prefers m4a, but seems that maybe most people are still using mp3?
I personally use .wav and .midi
But on a serious note, I use mp3 and some flac ( on another player).
Sent from my LT26i using XDA
320 .MP3s. All the way. Reasonable size, great quality and low overhead for playback. That or V0 compressed.
320 mp3 or FLAC (it's what I tend to get/rip)
I paid for PowerAmp it plays pretty much anything...

:laugh: great sound quality @ midi... Dolby digital 5.0 sounds like a SID against
AAC 256 bitrate from MP3 320 bitrate

AAC is much more effective that MP3. Same quality -20%. -5% of quality, -40% of size.

Does international s3 support hardware decoding aac or lame mp3

I stream all my music fro my server to my phone. I have decided to purchase a 64gb sdcard. So next step would be to convert my flac files to a lossy format. I'm deciding between Nero acc or lame vbr mp3. A lot of people suggests, that aac have the best quality per bit. But my concern is battery life. If acc is only software decoded on my s3, then I would prefer mp3, unless it's also software decoded.
