recording sound

[Phil Davis]

Robert,

I just re-read your post and realized my solution still couldn't address 
your issue - that of sound quality. Unless... is there an earlier 
version of LC where 44.1 khz stereo was supported? If so, you could 
build a slave app with that.

I suppose you could use a commandline app like ffmpeg to record. I've 
used ffmpeg to crop and convert media files from shell(), but never used 
it to record. Should be a way to make it work - maybe open as a process 
for update? Dunno.

Phil
