{{Template:FuncDef|MergeChannels(clip1 ''clip'', clip2 ''clip'' [, clip3 ''clip''])}}

Starting from v2.5 MergeChannels replaces [[MonoToStereo]], and can be used to merge the audio channels of two or more clips.
Don't confuse this with mixing of channels ([[MixAudio]] and [[ConvertToMono]] do this) - the sound of each channel is left untouched, the channels are only put into the new clip.

Before merging audio is converted to the sample type of clip1.

Example, converts "uncompressed wav" audio to a 44.1 kHz stereo signal:

video = AviSource("c:\divx_wav.avi")
audio = WavSource("c:\divx_wav.avi")
l_ch = GetChannel(audio, 1)
r_ch = GetChannel(audio, 2)
stereo = MergeChannels(l_ch, r_ch).ResampleAudio(44100)
return AudioDub(video, stereo)

Note, this is the same as:

video = AviSource("c:\divx_wav.avi")
audio = WavSource("c:\divx_wav.avi")
stereo = GetChannel(audio, 1, 2).ResampleAudio(44100)
return AudioDub(video, stereo)
