Mixes audio from two clips. A volume for the two clips can be given, but is optional.

Volume is given as a factor, where 0.0 is no audio from the desired channel, and 1.0 is 100% from the desired channel. Default is 0.5/0.5 - if only one factor is given, the other channel will be 1.0-(factor). If factor1 + factor2 is more than 1.0, you risk clipping your signal.

The sample rate of the two clips needs to be the same (use [[ResampleAudio]] if necessary). Your clips need also to have the same number of channels (stereo/mono) - use [[ConvertToMono]] or [[MonoToStereo]] / [[MergeChannels]] if necessary.

'''Example:'''

# mixes two sources, with one source slightly lower than the other.
video = AviSource("c:\movie.avi")
Soundtrack = WavSource("c:\soundtrack.wav")
Speak = WavSource("c:\speak.wav")
audio = MixAudio(Soundtrack, Speak, 0.75, 0.25) # The Expert may notice that the last 0.25 is actually redundant here.
return AudioDub(video, audio)
