...ks. Does the bitrate limiting engine have any linkup with psycoacoustics? -- it doesn't sound like it, at least not for lower bitrates. I'd experiment with adding in harmonics of the highest frequency coded to fill in the high end; it may be better to have a wrong high-end than no high-end, psycoacoustically speaking. Note that the Vorbis internals have changed significantly since I last really tried to study them, so pretend that I don't know what I'm talking about and you'll probably be right. -- Kenneth Arnold <ken@arnoldnet.net> - "Know thyself." -------------- nex...

Smack my curiosity, but I encoded some songs in Vorbis mode 2 and tried to be able to distinguish the difference between that and the uncompressed WAVs. (*smacks self*) but here's what I noted: It's actually kind of hard to tell the difference :) (and I consider myself to have a decent set of ears, though not anywhere near the best) I got my accuracy to about 90%, but I couldn't

Good Morning; Iam asking whether any one have knowledge about is it possiple to incorporate a psycoacoustic model?(specifically?I mean ?MPEG-1 psychoacoustic model 1) into the CELT codec(any version even older versions of the coder,?no matter) Iam using version 0.3.2. Kind Regards; Osama. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I've been "playing" a little with the floor1 encoding, and my game has posed me a question. I've been modifying (just curiosity) manually, and randomly (not too great modifications), the quantized [floor1_Y] values, just before coding them with the codebooks. As, if I'm not wrong, the [floor1_Y] obtained are then removed to get the residue vectors for each channel, I

Hi again. Since mostly stupid people gave me stupid answers last time, I will try again. MP3 and Ogg Vorbis use different models in order to remove most of the bits. What is the names of these models and how do they differ? <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

Hello I had an idea about judging the quality of ogg vorbis (or any other lossy codec) I took a wave-file and encoded it to ogg. Then decoded ogg to wav and inverted it's phase. When mixing the original wav with the phase-inverted decoded ogg-file, any identic parts of compressed and uncompressed audio should be eliminated. Of course there's always a "rest" of sound because
