Hi, I'd like to contribute to Vorbis and I think this may be of some interest for low bitrate coding. I have been experimenting with low bit-rate coding for the high-band (11 kHz to 22 kHz) and, though I haven't yet started quantizing my coefficients (a gain and an LPC filter), I expect to be able to approximate the whole 11-22 kHz band with around 1000 bits/s per channel (maybe even 500

I've been encoding my CD collection with mostely great results. However, there is the oddball that doesn't sound as it should (mostely I get flanging effects on high-frequency sounds like cymbals). I've seen people upload samples and post it here so that the developers might have a look at them. Now I don't have any online space. Is there an ftp site or something I can upload samples to? Or is this even wanted? Also, what about copyright issues? Anything I have to watch out for t...

After reading http://mp3.radified.com/mp3.htm I sent Rad an explanation of some things as I understand them. He liked it and posted it on his site (still unlinked, use the URL below). Can somebody with better understanding of psycho-acoustic terms and the vorbis model check it and comment on it? In particular I didn't know how vorbis handles quantization noise. If you reply with

...ith that stream, one can create the perception that an additional stream of 12-20Khz has been encoded. This effect is extremely usefull since altered (or artificial) frequencies below 100Hz and above 6Khz are enormously hard to hear! Especially in speech! In music this would translate to that the cymbals of all songs or drums sound about the same, and one can clearly pick the original recording from the compressed one. But for voice this is hardly noticable since very few articulated tones actually go over 10Khz. The letter 'S' and 'C' are two of them. By this a much higher...

...bum is ~50 minutes) while retaining excellent quality. My comments: 1.) most songs are transparent but there are still some glitches that appear occasionally (similar to glitch like in hf_glitch.wav that I sent to Monty) - these are probably high frequency glitches because they appear mostly with cymbals. Note however that these artifacts are rather subtle so if you don't have some listening experience you might not hear them at all. Still, in this bitrange, these artifacts shouldn't be present. 2.) gapless song come out perfectly! - no more clicks and pops - this is probably due to more...

dear vorbis developers, it would be very useful, if oggenc would support constant low-bandwith bitrates for testing. something from 20kbps to 44kbps, so anyone could test streaming over modem and isdn. audio quality doesn't matter. mörk --- >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

...anymore). The only artifact is in the second string of tones - they sound a bit blurry/watery. bassrumble.wav - sounds fine! horn.wav - there's still a small amount of noise/fluttery added. Maybe the bitrate is too low? (59kbps) glitch.wav - high-frequency glitch in the left channel when the cymbals are hit (at 0:03s).

...th a soundcard or three, and maybe a midi controlled mixer (I think MOTU made a 1u rackmount midi controlled 8 stereo port mixer or such). Not really an elegant solution though, but we could make a table that has the song name and weather or not to do a cross fade or a hard cut (some songs end on a cymbal crash or whatever). I was looking at NetJukebox or such, some php based playlist builder. Figured if we categorized stuff that would be okay, but that would require manually adding commercials and such. > Also a Linux-solution for > combining this with live-talk (moderation) would be really...

...lugin & listened for about 20 min. A few dropouts & 1 disconnect - but I'm on a flaky DSL circuit this morning, so that's hardly unexpected. Winamp reported bitrates from 26-31 kb/s. The sound quality was very decent, given the bitrate. I noted a few artifacts in the 6-8 kHz range (cymbals & electric-guitar harmonics) on an electric blues cut - similar to mp3 at 32kb/s, perhaps a little better. The codec really shone on the acoustic selections. Very transparent - with markedly fewer human-voice colorations than 32k mp3. The acoustic guitar also lacked the high-end grunge you oft...

...is eminently usable, with only marginal defects for normal usage. Already sent money, will do that again. * * * I spent at least 40 hours in the last week testing RC3. I selected a few fragments from pop, classic and jazz CDs in my collection, covering piano, harpsichord, voice, percussions, cymbals and complex arrangements. Also, downloaded a few samples from the Net. I listened to them with a decent Sony headphone, and looked at them through the spectrograms of CoolEdit2000 (have yet to find a good audio editor on Linux). I was able to see many more differences than to hear them, but it...

...plained: samples. Say you have a drummer repeating a drumloop. If it's recorded, there's no chance the noise of the drums will correlate, it will change all the time. But if it's a drum sample, they will match. It's easy to correlate similar kickdrums, but that hardly works with cymbals. Anyway, right now I get what I wanted somewhat working, well enough considering I've only spent a couple of hours. I've done matching-frame-detection at small & big level. Small is just a couple of samples, but I also tried big tempo-synced blocks (this wasn't a problem, I...

Greetings: Another test. I've re-encoded a batch of mono 22050 Hz WAVs, average bitrate seems to hang around 30-40 kbps. Icecast.xml is set for three connects, and the URL is here: http://64.108.112.145:8000/shouter.ogg IMO, the sound quality is much better now. Again, the stream should be up for about 45 minutes or so. Please let me know how it works for you... Best regards,
