Hello all, I'm having some problems with the sound quality of recent Vorbis. There is some kind of metallic echo/tremolo effect in the lower frequencies. This is on my iMac; haven't seen this problem on x86. If you need a sample, I can put one up somewhere, or mail it to someone with a good ftp server, preferably. It could be caused by the iMac sound system doing surround sound, (Dolby

Hiya, Here is the sources to my "rehuff" program. ./rehuff in.ogg out.ogg does a lossless recoding of a vorbis stream. (It generates optimal huffman codes for the particular stream). This code is meant for developers only, until someone is kind enough to provide good build and configure support for it. I won't. And no installation help questions please. There is a little patch

Hiya, Just downloaded beta3, and I actually got it to compile without too much hassle. Great job! Still, some problems: -- (easy): the -V option to ogg123 is broken, --version works. -- make profile doesn't work (in vorbis-tools), need to pass in some -pg -static or something like it (doesn't exactly work, -static is swallowed by libtool; read some docs, needs to be -all-static

Hello all, Finally I succeeded in uploading the test case I promised. It's at http://home.wanadoo.nl/segher/test1.wav.bz2 (It is a wav, the headers are a bit inconsistent, but encoder_example will be ok with it, as it just skips them). I did some thinking, and a possible solution is decreasing the ATH_Bark_dB[] for the lower frequencies. As the comments say, it's not really an ATH, but

Hiya, Find attached a new encoding mode. 100kbps. There's a patch as well; it is supposed to improve quality. Have fun, Segher p.s. To use the mode: add an #include "modes/mode_S.h" to modes/modes.h and force vorbisenc.c to use it. (Oh, and the S doesn't mean Segher. Really). <HR NOSHADE> <UL> <LI>application/octet-stream attachment: Unknown Document

Hi all, [For the uninitiated: a "peeler" is a program that transforms a Vorbis stream into a smaller, (somewhat) lower quality Vorbis stream, and does so quickly, by just throwing out some data.] After having prototyped several peelers that aim to peel to a certain filesize, or to a certain quality, with mixed success, I've now taken a different route: a peeler that aims for the

Some thoughts for the new year: 1) MDCT is good for image coding 2) image coding and audio coding are two very different things 3) combine 1 and 2 4) if a psycho model is good, after leaving out what it tells you you can without hurting quality, applying the same model should yield the same results as you got before 5) from 4: decode -> encode -> decode should result in (almost) the

Me again, this time not about patents but about wavelets. I've been doing some work on an image compression method which uses Haar wavelets plus VQ and entropy coding, and Segher Boessenkool told me in a private message that you are also doing a video codec. So I searched the archives and read a bunch of posts, but I never did find out any web address. And it's not on xiph.org either. So

I would like to see the following information added to the FAQ at vorbis.com, appended to the "Audio Quality" section. "Uiver," "boa," and "jonI" from OPN's #Vorbis channel contributed and reviewed it. "What does the 'quality' setting mean?" Beginning with vorbislib 1.0-rc3, audio quality is no longer measured in kilobits per
