Audio file format with time code

[Dr. Peter G. Baum]

Hi,

Which file format implemented in gstreamer supports up to 40 channels 
PCM samples with time code?

wavenc supports only 2 channels (why only 2, the NumChannels field is 16 
bit?) and does not support the broadcast wave chunk, which would add the 
time code.

Any recommendation?

Many thanks,

Peter
