[the tool i wrote to do this is available at http://www.geocities.com/SiliconValley/Heights/6494/sw/ it doesn't have a lot of docs, but does include source and executable (so it doesn't need the gsm lib, which iirc, needed some tweaks) and even does silence compression. "gsmplay -h" gives basic usage, the rest should be obvious]
