Hey again FLAC devs,
I managed to hack out another proof-of-concept multithreaded FLAC
encoder that is more amenable to streaming and also uses a fixed
buffer size. The performance is pretty much the same as my earlier
version; that is, I can encode a 636 MB wave file in ~7s with 8
threads on an

Frederick,
This is great news! Thanks for your effort.
Your proof-of-concept raises a few questions for me:
1) I know that the ratio of uncompressed to compressed data is
unpredictable, but I never really considered whether the input block
size or the output block size is constant. I'm ass
Hey FLAC devs,
I managed to hack out a proof-of-concept multithreaded FLAC encoder
based on the example libFLAC one. It turned out to be fairly
straightforward to get near-linear speedup; I can encode a 636 MB wave
file in 6.8s with 8 threads on an 8-core 3.0 GHz Xeon vs. 31.4s with a
single thre
