I think the .ana file created by flac -a [fname] is super easy to parse.. here is an example that reads and puts in database. after you have it in a database you can query stuff. https://github.com/waitman/inflaca this db insert work could also be done in flac/analyze.c but i'm under time constraints at the moment. -- Waitman Gobble Los Altos California USA 510-830-7975
