This mod will activate your front earpiece speaker in conjunction with the rear main speaker any time Speaker mode is used for example playing music, watching movies, shows, youtube and so on, creating an almost surround sound type of effect. "



" This post is a collection of all the audio related mods I have created from the OnePlus One. The mods are: Triple Mono sound, True Stereo sound, Main Microphone bypass, Speakerphone low volume fix, and Speakerphone low volume fix with True Stereo sound. If you have a request, then make it here and I'l try to make it if I can. " Click to expand...

True Stereo

I have enabled true stereo playback by putting the speakers on a different channel than the earpiece. This version of the mod will only be noticeable if you are listening to music that was recorded in stereo. Most music is recorded in Mono so I would recommend going with the Triple Mono version. This version is quieter than the Triple mono version.​

Triple Mono

This version plays all audio through one channel. This basically means that you now have 3 mono speakers and is what I recommend since most music is recorded in mono anyway. WARNING: MESSING WITH YOUR EQ WILL ALSO EFFECT THE EARPIECE. IT COULD POTENTIALLY BLOW IT OUT IF YOU INCREASE THE VOLUME OR BASS TOO MUCH​

Main Mic Bypass

This version bypasses the main microphone in case it is broken. When the main mic breaks, it disables ALL audio input even though the other internal mics are fine. The only way to fix the main mic is to solder a new one on, but this mod can temporarily delay this procedure by re enabling audio input from the other internal mics.​

Speakerphone low volume fix

I've seen many people have this problem. I think its due to the fact the the phone relies on the main microphone too much. What I did is instead of using the main microphone for both headset calling and speakerphone calling with the aux mic for noise cancellation, I made it so that the main mic is used for the headset only and the aux mic is used for speaker calling only. This has worked for some people but I can't guarantee it will work for you as well.​
