If you're using your audio device for live audio (ie. adding effects to audio from your guitar) you need pretty small latency. You can go a bit higher than 5ms without noticing, though. Most apps dont require realtime. For example, streaming a song. You dont care if the samples show up at year ear 2seconds after they were sent from your hard drive, so long as all the samples are delayed by the same amount.. You can stream this clear across the country over all kinds of cut rate ISPs and still get satisfactory results with enough buffering.. > Roman. Tim Newsham http://www.thenewsh.com/~newsham/
