We, and many other people are doing it. We're also are using a smart IOP streamer (Multistream rocks!), so streaming audio data has no EE hit. My conclusion on PS2 OGG (cool factor aside) is why would someone take an IOP hit decoding MP3 in software, when there already is hardware support for compressed audio at a 4:1 compression ratio (over WAVs.) You're not saving "that much" IOP / SPU memory. -----Original Message----- From: brian sharon [mailto:[email protected]]=20 Sent: Sunday, April 13, 2003 12:59 PM To: [email protected] Subject: Re: [GD-Consoles] anyone used Ogg Vorbis on PS2/GCN? Key points from the newsgroup discussion: But what I really got out of the discussion was a need to question the=20 ancient wisdom that you can't stream audio and data at the same time=20 (you'd think GTA3 would have caused me to do that, but I'm kinda slow=20 sometimes). On PS2, the Multistream library looks like it can give me=20 a pretty efficient implementation of streaming audio while streaming=20 data. Obviously on Xbox you have so much flexibility with the hard=20 drive that it's dead simple to do both. So the thing I need to figure=20 out now is whether I can pull off streaming music and data=20 simultaneously on GCN. And if not, maybe I'll end up using Vorbis=20 there. --brian On Saturday, April 12, 2003, at 07:55 PM, J. Grant wrote: > Hi Michael, > > Out of interest what was the conclusion of this discussion?
