Sort of off topic, but I was wondering about how the SBR data factors into an mp3pro bitrate. If you encode a "64kbps" mp3pro stream, I'm guessing that 64kbps would include the SBR data. So, when played in a normal MP3 player, would a 64kbps mp3pro stream actually sound worse than a 64kbps MP3 stream? Tony Arcieri --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

Hello everyone, ff123 compiled Monty's branch of the RC1 encoder, see his post on r3mix.net forum: http://66.96.216.160/cgi-bin/YaBB.pl?board=c&action=display&num=994299736&start=30 Anyway it only supports ~128kbps mode, so I did a quick listening test with some files that bugged vorbis beta4. grace.wav - the right channel is still a bit watery, and I think this can be seen

Well, in the world of audio compression it's never boring... :-) Full press release from Dolby: http://www.aac-audio.com/press/aac.pr.0104.AACencoder.html My comments: Looks like Dolby will start licensing AAC encoder that targets consumers and the products they use like CD rippers, jukebox players, etc. Also, it looks like that this encoder will be Low Complexity AAC ("The AAC Consumer

Yes I know this question has been asked many times, but since Monty said that RC1 will be released in July (actually a pre-release should happen before that), and since the month is almost over, is everything still on schedule or is RC1 going to be delayed? -- Vorbis Xtreme | http://solair.eunet.yu/~aldov/ Ogg Vorbis is the free, open source alternative to MP3 --- >8 ---- List archives:

I was a bit confused by that statement as well Lee. I've done a bit of work with mp3PRO using a source developed from scratch and a version of the original Icecast modified only trivially to deal with specific metadata requirements. There is a very high level explanation of mp3PRO at the http://www.mp3prozone.com/basics.htm site. At the risk of being somewhat incomplete i will add: 1) The

Following a post on vqf.com forum, I found out that some company called Adapted Wave Technology is ready to release its audio codec based on wavelets. They say that this wavelet-based codec is superior to MDCT codecs by 30-50%. One sentence caught my attention: "Adapted Wave Technologies holds exclusive patent rights for applying wavelet packets to audio applications." - sounds like a

I was doing some testing with RC2 and I noticed that RC2 doesn't encode past 19kHz with this clip (-b256 and -b350). There are no problems with this clip like it was before, but this clip contains signal past 19kHz which is audible as a faint high-frequency hiss - and that hiss is gone in the encoded file since RC2 cuts off at 19kHz. I think that -b256 and -b350 should encode at least up to

Watch the film: http://www.filmwave.com/mp3/ Plot: In the year 2002, the government has outlawed MP3s and any related material including Napster. The FBI has created a department called the MP3 Task Force to help combat illegal MP3s, the Task Force are two former musicians, Agent Farley, and Agent Hopkins, together they will infiltrate the MP3 black market and put an end to MP3s forever.

There is a bug in winamp plug-in tag editor that corrupts files encoded in -b192 mode - these files have trouble with seeking. So get the latest plug-in: http://www.blorp.com/~peter/zips/in_vorbis.exe If some of your files have been messed up by this bug, you have to re-encode them. --- Aleksandar @ Vorbis Xtreme | http://solair.eunet.yu/~aldov Ogg Vorbis is the free, open source alternative

I couldn't catch Monty on IRC, so I'll ask here... how's RC3 coming along?

Important (imho)! I found this site in the internet: http://www.plusv.org/ PlusV is an audio enhancement algorithm similar to SRB of Mp3Pro, but 1) better than SBR 2) Fully open-source It seems to me wise to include PlusV into new versions of Ogg Vorbis. P.S. what about some long-awaited features in Ogg Vorbis? 1) ability to turn off the frequency filter in the encoder (especially for high
