用OkeOke可以按比例混合 原唱 and 伴奏 声道。
我的问题是混合后的声音音量不正确。我用50%原唱 and 50%伴奏,混合后的声音要比单一原唱或者单一伴奏 声道声音都小。

Ratios of audio 1 and audio 2 are r1 and r2, and r1+r2=1
Aout = A1*sqrt(r1)+A2*sqrt(r2)
In case r1=r2=0.5, Aout = 0.707*A1+0.707*A2.
A1 and A2 are the volumes of audio 1 and audio 2.

I made some change on the sound mixing. I think it should be working
better now. Please do the auto-upgrade and try it out.
Thanks,
