Watchdog timeouts? Sounds interesting. Will look into it. You computer should be more than fast enough. Are you running off batteries perhaps? I'm not sure about how the power saving modes of os x might affect performance. It might help to increase your sound card's buffer size if it is less than about 512 samples. > My system is MacBookPro 17" 2007 2.4Ghz Core2Duo, 4G Ram, OSX 10.5.8, and a > MH ULN8 sound interface.

If you want to dig into this, I recommend this paper which spans a bit wider than the title suggests: "A New Method for B-format to Binaural Transcoding", Svein Berge, Natasha Barrett (2010) <http://harpex.net/aes40-free.pdf> Svein -------------- next part -------------- An HTML attachment was scrubbed...
