Re: Web Audio API availability for Windows and Linux


I've just updated audiolib.js and now all my demos work again on both APIs.

I tested the Windows and Linux builds and they're both working very nicely!

Sidenote: the performance on Linux seems to be extremely superior compared
to Windows, on Linux I get faster than ASIO latencies, can't manage to press
enough keys to make it break (in that it's also superior to Firefox to my
surprise), however on Windows there are audible cracks as it becomes more
easily stressed, and also the latency is noticeable, and there performance
is inferior to Firefox. That is on a dual boot, shouldn't have anything to
do with graphics rendering, I have broken drivers on Linux. Is there any
particular reason to this? I'm running Ubuntu 10.10 and Windows 7 Ultimate.
Is it the backend (DirectAudio? ASIO is probably out of the question...)? I
recall observing the same performance difference with Firefox as well.

Anyway, a long wait rewarded, thank you, and congratulations, Chris!
