Thanks for the patch. It seems to work fine, except for bitrates. What
is the source that you used for the format info? I've encoded a small
file consisting only of silence and all applications report it to have
3 kbps. Your code reports 1411 kpbs, which is what I get when I
convert it to a wav file. Is it possible that it's the bitrate of the
uncompressed audio data?
