[FFmpeg-user] Mapping multiple audio streams

Suppose I have an input with n audio streams. If I want to generate a
separate output file for each stream is there a way of doing this via a
single command? Bearing in mind the number of audio streams in the input is
unknown. Would I need to interrogate the input first and determine how many
streams it contains?
