True, but in this case it never comes at all. Mysterious. And the disk would appear to be awake being that we just played from it. I've done a fair bit of stuff cutting up sound files in random ways, but its always got to be arhythmic if we can't guarantee the start time. I imagine when we can read sound files inside threads we can preload each section and get it to come in sample accurate. > >best, >alberto > > _____(( http://crucial-systems.com _________________))_______ ------------------------------ Date: Sun, 16 Jul 2000 02:31:53 -0400 From: "crucial" <---@---.---> Subject: Re: ? > > > > > > > ... will we be able to trigger a printer to print ? _____(( http://crucial-systems.com _________________))_______ ------------------------------ Date: Sun, 16 Jul 2000 02:36:35 -0400 From: "crucial" <---@---.---> Subject: 24bit question Apologies for so many posts, but I forgot the 24bit question...
