How to increase sound loudness by 6 dB in Android?
<p>Recently I integrate an audiofx into Android. It attenuates the sound by about 6 dB, so I need to do the other way around. I do that in <code>MixerThread::prepareTracks_l()</code> and modify the corresponding value in <code>mStreamTypes[]</code>, but I don't know whether to add or to multiply a value. </p>
