Excerpts from Kevin Cosgrove's message of 2010-06-24 05:49:50 +0200: I assume you mean a combination of general purpose lossless compression & audio lossless compression? Otherwise just tar.xz or whatever should be easy enough. In case you want the lossless audio compression I'd say use wavpack, because it can handle float formats as well. I've never done such a thing, but I guess you could do it like this: give the project dir as argument, then it searches through it for wav files by extension or maybe using 'file' or something, compress those using wavpack, then compress the whole dir using .xz or whatever. To decompress, decompress the .xz, search for .wv and decompress those. I might be missing something. -- Regards, Philipp -- "Wir stehen selbst enttäuscht und sehn betroffen / Den Vorhang zu und alle Fragen offen." Bertolt Brecht, Der gute Mensch von Sezuan
