That's a very interesting question. Do any of the existing tools
report these factors? Maybe there is an option for flac which will
show some numbers during encoding, or maybe metaflac has an option
for reporting some stats on an existing file.
If there isn't an existing option for either of the standard tools,
then you might have to write some code using the flac library to scan
through a stream and report statistics.
