Yikes! Then what I'm reading from your post (and others) is no, I can't do
it my way. ;) It *did* seem a little too easy, after all!
I can't speak for video (and I'd imagine it's a factor more difficult)
but it's really not that hard to concatenate audio in python. What you
need to do...
Import the right modules for the audio formats you want to read.
Decide on a master output format, say CD quality - PCM 16bit 44.1Khz Stereo.
Open a file for appending
Read through each of your source files loading them into memory
Get the sample rate and format
Run the sample data through a function to convert it to the master
output format*
Squirt it to disk
Finally take the resulting file, calculate a new header and munge the
two together. Voila :)
*I'm sure several modules have functions/methods for this but it
wouldn't be very hard to roll your own either.
