Sorry for the crosspost but I think it's important. Tom Pepper of Nullsoft, posted this yesterday. "We've considered heavily which direction seems most appropriate for the second generation audio codec of SHOUTcast. Our primary goal in the decision process was to provide smaller consumption of bits while maintaining similar quality and compatibility with existing playback systems. At the same time, the open nature of Ogg was very compelling, and established the baseline of acceptance regarding cost of encoding systems (free to the end user.) Also of significance was the extent which other applications would be able to play back the audio, including our most popular players (Winamp, iTunes, and RealPlayer, respectively.) In the end, Ogg didn't measure up as our best candidate. We still think Ogg is a worthwhile codec, and as such SHOUTcast-streamable support for it is available via NSV. While I can't yet announce the precise codec we'll be using for the next 3 year run, I will say it is making me very happy to see 56kbps streams outperforming (from a purely subjective "quality" analysis) current 128kbps streams, and the cost of the encoding seems manageable enough for AOLTW to continue absorbing encoding and decoding costs, not to mention the majority of playback devices and applications will be supporting the codec as well by 2004, if not already." ------------------------ Perhaps we need to convince Tom otherwise. It is likely to be AAC or WMA they are going with. Once they change codecs from MP3, it is unlikely they will want to change again.

I think without that information, any advocacy (or attempt at improvement) would be sort of futile. --- Stan Seibert <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

IMHO he should pay a bit more attention to licence issues. <p>Bye. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

I don't know of any codec providing at 56Kbps a quality better than mp3@128. --- Could Tom have been refering to HE AAC? The web site http://www.nerodigital.com/ *claims* that it can do cd quality at 48kbps. (Of course, Windows Media said the same at 64kbps and we all know better.) It uses the same technique as mp3pro does, except with AAC. Although mp3pro was hardly perfect, it was undeniable that it did significantly improve upon the plain mp3 format. Which is the same basic techniques as the old mp+ used with the mp2 format, right? Would that improve a future version of Ogg? <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Nullsoft Streaming Video. Basically a video container format. Can be used for files or streaming. Though it can use any audio video formats internally currently it is just VP3/MP3 (or VP5/MP3, but that's internal only and not publicly available). Basically video for the next version of SHOUTcast. http://www.nullsoft.com/nsv/ From: "Geoff Shang" <gshang@uq.net.au>> BTW, what is NSV, anyone know? > > Geoff.--- >8 ---- List archives: http://www.xiph.org/archives/ icecast project homepage: http://www.icecast.org/ To unsubscribe from this list, send a message to 'icecast-request@xiph.org' containing only the word 'unsubscribe' in the body.

So it would appear to me that operating systems other than windows and mac are not on their raidar. This is unfortunate and disapointing, given that they themselves use and provide servers for several *nix variants.

Hi: A friend sent me a press item saying that AOL was changing over from realaudio to MPEG4AAC. I can dig it out if people are interested. Not sure if this is in any way related, but it might well be. BTW, what is NSV, anyone know?
