Here are 2 settings that work for .wav sound effects:
22050Hz 16bit Mono 352kb/s
22050Hz 16bit Stereo 705kb/s
among others.
for music it's .OGG:
44100Hz 16 bit Stereo and almost anything for kb/s
Maybe i must try make all sound in ogg? Or better use wav?
My sound have very low kb/s
if need i can upload files
