Some first impressions of Snd/CLM and threads: on a machine with 2 quad-core 3.0 Ghz 86-64 processors (8 "cores"), I can currently get with-threaded-sound to run about 4 to 6 times faster than with-sound, and multichannel edits (filter-channel) run 6 to 8 times faster. I'm still chasing race conditions and so on, but this looks promising. Also, if you have 8 GBytes or more RAM, you can now use that 2^32 element table-lookup you've always wanted -- I think all vct, sound-data, and clm table sizes can be off_t's. Use mus-fft for an fft in that size range (and take a vacation while it computes).
