[Galaxy S II Android Development] mcpdigital:
Some info for people that has doubts about the sound stuff (AWBeats and Ac!d). Not the ones that have all the answers ok.

I'm not asking anything here, if you are thinking in suggesting me to avoid bricking my phone or reading the thread once again please DON'T.

If you have better information or need to correct some of my information, please do that to help other people.

If you don't like the post, just don't thanks.

1) AWBeats is installed with JBam v.1.0.0 and v.1.1.0 no matter what you choose in Aroma, it is always installed. At least for me.

2) Removing the apks using Titanium or other methods do not remove the libs of AWBeats and do not bring your original DSP Manager back. You need to do it manually deleting and replacing all the files of the package and removing the build.prop lines referring to the AWBeats stuff.

3) Installing Ac!d V5 over the JBam will not make it work, it will just mess with AWBeats already installed by JBam.

4) The same 3 points above are valid/true for the Ac!d package installed by JBam 11/25, not removable by simply removing APKs and not replaceable by AWBeats.

5) AWBeats that come with JBam does not work with Poweramp. No changes. No improvements either. At least for me, tried many times.

6) The equalizer curves used by some AWBeats users here seems to almost eliminate 3 of the eq bands, so that's why no one hear the distortions anymore, but the music is not being played as it should, without those 3 eq.freqs., Maybe for some kind of music it does not matter, but I miss those freqs in most of my music.

7) Ac!d mod, differently from AWBeats, not only changes a lot of low level stuff (as in AWBeats) but is effective even when not fully installed (all the features). What I mean is it gives better sound to all players, not only to Apollo or GPlay Music, but for Poweramp and others too.

When you have a fully functional Ac!id V5 with the Sony stuff you will get one Sony equalizer called Sound Enhancers and some Virtual environments that appears in the form of some Graphics designs together with the Sony Sound Enhancers. You can check what I want to say here: http://xdaforums.com/showpost.php?p=34809856&postcount=300 Very few people in that thread was able to have a complete install of Ac!d or even see those options.

8) All this information is already in the various Ac!d threads not only in the latest Acid V5 thread, so nothing really new here. Everything including the not possible to removal of it, other than installing a ROM from scratch.

Lots o people are having a hard time installing it, and a hard time modding build.prop and with lots of bootloops, missing sounds after install and cannot just uninstall it. This mod doesn't work well for all phones and ROMs, and JBam is getting more generic than specific for S2.

That's why iGio90 removed it and included AWBeats. And by the way he prefers AWBeats too, and it is his ROM so he can do what he wants with it.

ALL the mentioned procedures (install/uninstall/remove/overwrite) were TESTED by me using 2 different Galaxy S2, one with JBam and other with AOSP based. Same results. So feel free to test it if you need.

Some excerpts from the official V5 thread:

Little Tips:

- I REALLY SUGGEST YOU TO USE AC!D AND WALKMAN ONLY (without any other Addon) (in my opinion gives the best audio quality) (but walkman might not work on All devices)

- If you can't change volume level in walkman just click on audio effect it will resolve immediately this issue

- ALWAYS FLASH ON A CLEAN INSTALL!!!

- Once it booted leave your phone 5min to let all effect settle then reboot once again!

- DON'T FLASH ANY ADDON IF YOU FLASHED WALKMAN ADDON (NOT COMPATIBLE)

- (Walkman addon may cause bootloop on some devices cause it takes space in system partition)

- IN CASE OF BOOLTOOP ---->REFLASH YOUR ROM AND THEN TRY UNIVERSAL VERSION<----

AC!D Audio provides you an overall better sound quality, more precisely:

● Bass are deeper, crispier and more powerfull, with nice effect without distortion and crackling

● treeble are less aggressive and more immersive (you'll enjoy whistle, whisper, instrument like piano, guitar,... will be much more natural and balanced)

● Voice is really more natural with better balenced EQ for a pure cristal sound for an awesome clarity

● Audio track quality will be enhanced and the improvement will be even noticed on your most crappy headset (even if good headphone are really suggested to enjoy all improvement of this MOD)

This Engine is A port of several Audio Technolgy, each of them are well know to enhance some specific audio part, our goal was to get them working simultaneously with a lot of personnal optimisation modification tweaks and unique features by our Team

That's it, the above thread can enlighten some of other questions.

Bye
