问题
I am actually mixing two wav files using the simple equation (a+b)/2 where a and b are the samples from the two wav files.This is fine and I am able to listen the audio from both files at the same time. But the problem is there is a lot of hssss noise (similar like the radio) playing in the background,how can I get rid of this white noise/noise.
