similar to: improve CELT

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:

Hi, ?I'm trying to improve CELT according to the bit allocation problem and psychoacoustic masking which was mentioned in the paper "A High-Quality Speech and Audio Codec With Less Than 10-ms Delay". What software version do you prefer for me to choose?on my study? Best Regards, Osama Y. Fadhil. -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I want to make a static database containing hundreds of thousands of very short audio files, each having not more than 100 milliseconds. These are made by splitting larger audio files into tiny pieces. I encode all the little files separately, but do not store 3 vorbis header packets, which are the same for all the files. I do not use ogg stream, only store plain vorbis packets.

Hello vorbis developer! I'm not very experienced in informatics, cause i'm only an audio engineer and sorry for my broken english but i have an idea... After the filterbank the maximum aplitude in each band decides about the nessesary bits, then the psychoacoustic model decides how much of the signal can be truncated without hearable noise. What do you think about quantising the

Hi, I'm studying at ETH Zurich and want to use a pyramid vector quantization for my semester thesis. Unfortunately, I have some troubles with generating the codebooks for high dimensions. For vectors with dimension bigger than 12 it takes such a long computation time to generate. I thought maybe you could help me out with a efficient way to do this? Is there some code available? Thanks for

I've made a block diagram of the encoder because I tried to find out, how it works http://stoffke.freeshell.65535.net/ogg/block.html Although there are specifiation docs, that give very detailed information about single aspects of the encoding (or decoding) , I'm missing documenations that give a more general overview, about how the encoder works. (Vorbis Illuminated seems a bit

Hi everyone, I've just made the first public release of some new *experimental* codec work I've been doing (part of the vague Ghost project) with help from Monty and Timothy. This is mainly intended with developers with DSP knowledge, not for doing anything useful with it (but it does encode and decode already). Also, the main idea is *not* to replace either Speex or Vorbis, but to code

Hello everyone, I'm a student at the Universtiy of Delaware, and will be soon starting some research on the effects of lossy audio compression on speech sounds. I will be preforming test with both mp3 and vorbis. First of all, if I use the '--ogg' switch to lame, does lame use GPSYCHO to encode the wave, or some other psychoacoustic model (perhaps one designed for

[ I'm not in the list because I didn't find a digested version; please move the lists to sourceforge.net, and we would have the digested version. I read the replies from the archive. ] Hello. Would it be possible to allow Vorbis use the same codebook for multiple files? I could keep a 650 MB codebook on CD-R and use that for all my audiofiles. If that is possible, how much the

Well, this question comes once and again. I have RC3 and Garf's RC2 tuned versions (160 and 350) in a nice graph. Nobody should be surprised that RC3 is better, but in some cases GRC2 shows better EAQUAL/bitrate results. There seems to be room for improvement in RC3 with some tweaking. See it by yourself at http://audio.sinderman.com/ Cheers, AGS.

I sent it first without subscribing, but it seems like it got stuck in the moderation queue, so I subscribed and re-sent it.] I'm doing some work on audio fingerprinting for a school project (more precisely, my master's thesis.

Hi All, It is possible to make Opus/CELT a lossless coder if I allow a sufficiently high bit rate? We considered using FLAC, but FLAC's latency is well beyond the acceptable range.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Celts, I've become intrigued by the problem of spherical quantizers, so I decided to see if I could come up with something better than PVQ. What I wound up writing is something I call an "octagon quantizer. In two dimensions, PVQ uses a "diamond" (square) shape. An octagon code (OVQ) uses an octagon, which is a much better
