I am starting this thread coz I have been observing Audio stutter in each & every MIUI/CM9/AOKP cROM made for i9003.
Tried allmost all kind of popular music player available, but none of the player was able to remove the audio stutter.
I tried all possible remedies, like:-
-Removing DSP
-With DSP
-Without any custom equalizer
-Different bit rate for mp3 files
-Different format s of audio files
I asked lot of times in different forums but got no response.
I think this is a very important thing along with other issues like Backlight/Blacklight/Camera/Battery life/smoothness for a cROM.
I hope to get resolution for the same.
Right now there is no solution at all. Dhiru is working on audio files. But he is more worried about kernel 3.0. For camera, hardware acceleration, smoothness kernel 3.0 is the only option.
This thread should be in general section.

Thanx for the reply....!!
I know Dhiru is working very hard and his priorities are different, but this stutter thing is pretty annoying.....!!
I hope i will get my query answered here thats why didnt post in General section. If its violation of forum rule I will move it.
Use a player with buffer like poweramp and set it to the high valor
I flashed beats audio after installing dhiru' s rom... I'm not getting any audio stutter..may b this is the solution ..or not.. I don't know...finally I'm not getting it

Don't use MIUI launcher. (this is the worst)
Delete MusicFx from AOKP/ Dspmanager from ICS.
Use Instinctiv / xPlay Music player (both are free)
Or flash the attached player.
This will reduce the frequency. Does not completely remove it.
Shutter issue was fixed in Alpha 4.

No, It is still there and very irritating too. U hear screeching sounds sometimes.But most of the times it is a stutter.

I have removed Music FX from AOKP rom and installed Instinctiv music player....!!
Now the stutter has gone but, there is a very small break instead of stutter..!!
But anyhow it is way better then the annoying STUTTER sound.
And the interface is great in this player.
Thanx.

The loudness of the stutter is quite low compare to pre aplha 4, but its still there.
Trying different players only reducing the frequency of stutter. Sometimes it is like a break in place of stutter sound.
So this may have something to do with the MP3 decoders. Currently we are using software decoding for all AOSP roms since we don't have a proper functional DSP.
I see no issues with the Audio HAL that might cause the shutter since there is no such issue when dealing with basic sounds like Ringtones or Notifications. Have you tried playing lower bitrate MP3 songs? Does it still shutter?

ur right....!!
I have observed Upto the bitrate of 128KBPS the stutter is very low & with higher bitrate the stutter is very much increased.
But have not tried any MP3 file with the bitrate of below 128kbps, will try to play one to test it.

Im using Playerpro with the DSP pack,i have deleted the DSP manager from system apps,i have no shutters at all works perfectly,oh btw there is a setting in Playerpro with Dsp pack to increase or decrease the Audio Buffer,may be that made the shutters go away,in short i have no audio shutters at all

Its not over yet i posted u before @ ur thread with logcat. It keeps shuttering as the system try to free memory.
If u want logcats i can provide u many i dont wait much time to have a shutter

A workaround:
It's due to the load on the CPU. Generally, the sound chip on a system handles all the decoding and DA conversions, but here, the CPU is taking on the load instead.
Using the "V6 SuperCharger" script and Poweramp's higher priority settings, along with DVC enabled, I've got the stutter down to a minimum (it still stutters when running taxing applications like Chrome Beta). I suggest using the "V6 Supercharger" scripts for now.

You need to use a Script execution program such as Script Manager (Free - Ad Supported).
Doesn't need to be executed every startup. It's a One-shot type of script.
I recommend reading through the OP before executing.

will it remove stutter? and also could anyone make a flashable zip for that? :/
Hi I'm just wondering if there is a fix for a problem I'm having, when I play music it stutters the sound I've tried different music players to resolve the problem with no luck. Any advice would be great

I'm having the same problem. But only with AOKP roms, started after build 39. And I dont have the issue with CM9 or Sense 3.6 or 4 based ROMs, but i really love the toggle switches in the AOKP notification widget
did u full wipe before upgrading rom? because AOKP is known to have audio routing issues and it is fixed in some version (sorry, i did not keep up with the updates)
hope it helps =)

I've run into this problem as well, and yes I do a "format everything but SD card" prior to installing each ROM.
I noticed it first in the AOKP-based ROM EyeCandy 3.0. Whatever the dev memnoc did between that and the final 3.1 release fixed it, as a clean install of 3.1 removes the audio issues.
I'm still having the issue with the AOKP-m6 based ROM Supreme Blue

I've tried a bunch of rumored fixes:
installed awesome beats - audio still skips, but it now skips in high fidelity lol
installed DSP manager - did absolutely nothing, save provide me with an equalizer for the skipping audio
installed poweramp - this fixed the audio, however it was ONLY fixed when playing media through poweramp. Slacker, Pandora, TuneIn, Dood's Music, etc. all STILL had skipping audio issues.
My guess is that one of the default system audio libs isn't behaving nicely. Poweramp I would guess circumvents this with by using its own lib?
I have never used the eq or dsp manager on any 4.2.2 builds. I'm running slim build 4, and I don't know how to get to an eq. I ended up installing the viper audio mod. Which installed fine, I just need to read the directions on getting it to work with apollo and or playerpro.
What DSP manager are you guys using? Back on CM7 I used to use either the built in DSP manager in settings, or Volume+.
What is MusicFX and what does it do. How do I get the eq working in apollo?
Thanks for any assistance or advice.
In my experience MusicFX works only with the Samsung player and can't be used with other players. For the DSP , I would not use it cause a lot of times you'd get echo in phone calls, again my experience. I also use Volume+ which I find works well on any build of android. DSP is a very good app unfortunately as I mentioned a lot of people had the echoing on the phone while in a call if you can live with it then use it. Am on TW rom now but I did try CM10 and AOKP unfortunately never had luck with DSP.

For viper will have to put it in safe mode to get it to work on Apollo.
Changes made through DSPManager are not modifying the audio output. DSPManager is selected under the music effects control panel. Second phone on Slim Bean 4.2.2 which has experienced this problem. Build 7 and now Build 8.
Have downloaded EQ, Volume +, same issue. No adjustment to sound whatsoever. Any ideas? It would be nice to adjust the levels. Thanks!

You should drop DSP Manager and install Viper4Android. If you're interested in checking it out, search the XDA forums for it. It's the best sound mod by a long shot, in my opinion.
Just use Titanium Backup to backup DSP Manager in case you want to revert back to it, for whatever reason.

I have LG P500 phone with ICS rom. When playing music there are pops (dropouts) in sound. In PowerAmp I can adjust audio buffer size and it solves the problem. But with Google Play and other apps(podcast players) I can't do this. So I wonder is it possible to adjust sound buffer size to make all apps work smoothly. Thanks.
Beats manager
I think beats manager can do something for you.
