Lay audio from .wav to a blank video via avisynth?

[trapp]

I have a .wav file (about 84 minutes long) with regular audio on one channel and audible ND time code on another channel. (I’m afraid I don’t know enough to say exactly WHAT channel that is – is there a Channel 2 on a .wav file? If so, I imagine that’s where the TC is.) When I listen to it in MediaPlayer, for example, the TC track is heard as an (annoying) clicking.

I’d like to create a blank video file and lay the “regular audio” against that – create a video file (with no picture, just black screen) of what was originally just audio, and, of course, without the annoying TC sound track interfering with the “regular audio.” (Uncompressed audio would be great.) Is this something I could do with avisynth?

To gild the lily, I’d like – if possible – to convert the TC info on the TC track into a visible SMPTE window on the video file. But if that’s too complex, just getting the Channel 1 audio laid against a black screen of video would be great. I could lay down an arbitrary SMPTE code against that myself and worry about working out the sync with the TC track on the .wav later.

Thanks,

John

video = BlankClip(...) #parameters as needed
audio = WavSource("c:\file.wav")
mono = GetChannel(audio, 1) # try 1 through 6 until you find the desired channel
AudioDub(video, mono)

Thanks for the helpful code. It worked great!
