As Gene says the audio would be single channel 16 bit signed PCM in
little-endian order at a sample rate of 44100.

The relationships between various container formats (avi, quicktime, mpeg
program streams, etc.) and the codecs they can use are not exactly
straightforward but the first site above gives some info (look at the
discussion under "Advanced Video Compression").
