...group listening test of various formats to show how Vorbis 128 has improved since RC2. I have prepared three sample music clips comparing Liquid AAC, MPC, pre-RC3 Vorbis, Lame, Xing, and WMA8, similar to the first test. Except I believe that this time Vorbis will rank up near the top. http://ff123.net/128test/instruct.html ff123 --- >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.

I've been looking around for a tool to compare the quality of different audio files, didn't find anything, and so botched together something over the past few days: http://www.btinternet.com/~jfchapman/files/mcp.zip (Win32, 266Kb) It's just a small tool for playing up to 3 files simultaneously, with the ability to switch between the outputs to compare the sound quality (formats

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.wa...

...nc, and probably performed better than Lame 3.88b using --nspsytune at the same bitrates (except for the two samples above, which pulled down its rating). From my own subjective listening tests, I'd agree that Vorbis beta 4 sounds better than the best mp3 codecs at 128 kbs for most music. ff123 --- >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.

...nd like some tones are beating with others. I identified the Vorbis encode 16 of 16 times in an ABX test. I don't think it has anything to do with pre-echo: it's just a mass of people in a chorus. Fraunhofer's FastEnc at 128 does sound worse to me, if that's any consolation. ff123 --- >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.

Hi, does anybody know where I can find high quality samples that are in the public domain? It's a plus if they're samples that many codecs have problems with, because I want to use them for a blind test.

Congratulations on inclusion in the Real Helix thing. :-) I do have a question, however. While I am very impressed by Vorbis 1.0's quality even down to "-1", vorbis seems very much a VBR format, which is great if the file lives on your hard drive, but a mixed bag for streaming over a modem connection. How well does Vorbis compare to existing streaming formats, including

The following is a highlight of the interesting things that have been mentioned or announced. 4.1. New Listening Tests ff123 [19]invited all to participate in a new listening test comparing Vorbis at 128kbps from CVS against RC2 Vorbis, WMA8, and other codecs. He expects Vorbis to be much improved from it's earlier scores (which were already very good). 4.2. Another Proposed Hardware Project Pulkit Khan...

I won't bother quoting all of Moz's statements of how sound is interpreted by those blessed/cursed with tape recorders in their heads :) I will add that his whole explanation of perfect pitch perception easily offers an explanation as to why some individuals will only archive flac/pac/ape (Moz - do you?) and those of us that do not perceive that level of detail and are fine using ogg

Hi all! I ran across another song that oggenc seems to have trouble to encode. The intro of U2:s "Grace" gets its right channel messed up by oggenc, even at the highest bitrate. Why is the bitrate only 218? Isn't that awfully little when asking for 320? Qualityflaws like these is the reason i prefer mp3 and mpplus today. But vorbis is getting better for every beta, so keep up the

Hi! I am very pleased with the progress that Ogg is making, expecially after I read the latest comparision tests on http://ff123.net/128test/instruct.html that put OGG on top aside with MPC. BUT the APPLAUD.WAV test case ( http://lame.sourceforge.net/download/samples/applaud.wav ) still produces **VERY** easily audible high-frequency artifacts when encoded with OGG RC3 up to q4.9 (!!!). Things are **MUCH** better from q5.0...

...this. If Monty can work this kind of magic for lower bitrates (and sampling frequencies) too, I cannot see any competition from any proprietary streaming codec, Real or Imaginary. ;^) I did not test any previous version. From Monty's comments to the WayItIs sample in the listening test at ff123.net, and from other comparisons in the last months, I gather that there's been a lot of optimization done to this release. I understand that there's a lot of people working on Ogg and Vorbis, and I really appreciate the work of you all. It looks like the core codec work is done by Mont...

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

I compared quicktime aac and vorbis,i think quicktime aac is better than vorbis at 80Kbps. please tell me if i'm wrong. using command: qtaacenc.exe --tvbr 31 --highest --samplerate keep test.wav qt.m4a oggenc2.exe --raw -q 1.6 test.wav -o vorbis.ogg the version: qtaacenc version 20100725 with QuickTime 7.6.7 OggEnc v2.87 (libvorbis 1.3.1) links:

Guys (and girls), I\'ve been testing Ogg Vorbis quality at home, and I thought I\'d share the results with you. For those who want the conclusion, Vorbis 1.0 RC3 sounds better than LAME 3.70 vbr/cbr (which I\'m told now that it\'s broken for VBR), at less bitrate, however, it\'s not perfect (and probably never will, since it\'s a lossy audio codec) and could use some
