...Emphasising the BOOM in BOOMSOUND...
A mod which significantly boosts ONLY the speaker volume.
The volume mod will activate as soon as you enable Beats Audio Beats Audio will act as a switch for the volume booster so your speakers will be louder whilst keeping the Beats Audio effect/processing
This will NOT work for AOSP roms because Beats Audio isn't available on there. Only compatible with Sense and GPE ROMs because we need Beats Audio to activate this. And no, Beats Audio can't be ported on AOSP ROMs.
First of all, I already had an idea of how to increase the speaker volume. The amp (TFA9887) uses it's own configs in the /system/etc/TFA folder but the problem is, we can't edit most of the files with just using a text editor. We couldn't increase volume using the normal method (edit snd_soc_msm files) because HTC removed all of the speaker lines in the files. Secondly, the only text-editable file I could find was the .eq files. I knew Beats Audio could be enabled via the switch in Settings so I thought it would be a good idea to change some values in the .eq files to increase volume. The main function of equalizers is to increase the decibels of specific frequencies right? That's how I found out that those files could be the ones I've been looking for. My first attempt at increasing the volume was to change the values from 1 to 2. Big mistake. Even though it looks like a small increase, my speakers almost blew up. The audio was LOUD, it was so loud that it caused so much distortion. It was definitely too much for my liking. So I changed the values to 1.0000000001, 1.0000000.1, 1.0000001, 1.0001 etc. and let my tester (@Cj719) test the volume. He told me that there was a slight change in volume so I tested it myself and thought that it wasn't enough. I then changed the values to 1.1. That was the ideal number for the speaker boost. When me and Cj719 tried it, it was just perfect. It was such a drastic change in volume but not as much that it would create distortions or blow up speakers.
This will only work on HTC Devices with HTC BoomSound stereo speakers. This will NOT work on any other HTC Device without the BoomSound Stereo speakers.
If you are using another device instead of M7_U/M7_UL (HTC One International), please mount system manually from recovery before installing or else it will NOT install for you.
@Cj719 - Without him, I would of blown off my speakers now! Thanks a lot for testing!
@Jonas2295 for encouraging me to boost the speaker volume
Everyone at Team Renovate for supporting me and testing for me
Everyone who participated in the discussion of speaker volume boosting in my Project ERA soundmod thread
Feel free to include this in your ROM/MOD, but it is mandatory that you credit me for my work.
Please, don't steal my work.
