encoder block diagram
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.

Speex for sampling freq >48KHz
Hi, I have one doubt again, that is Vorbis use DCT/MDCT based algorithm and also use psychoacoustic model so this is lossy codec. And I dont think it ca regenerate a better matching waveform than speex. Then there comes FLAC which is the perfect answer to my question, I suppose. But my concern is this that FLAC use simple prediction algorithm and doesnt use any CELP based algo which could have

Plot data in sequence
Hi r-users, I would like to draw line plots. However, the plot starts from 11121 data and plot data ENTRY last in the plot. Here is the code and data. datn <- read.table(header=TRUE, text=' LEVEL STATUS CGPA DIPLOMA ENTRY 3.32 DIPLOMA 11121 2.91 DIPLOMA 11122 2.90 DIPLOMA 12131 2.89 DIPLOMA 12132 2.89 DIPLOMA 13141 2.93 DIPLOMA 13142 2.96 DIPLOMA 14151 2.76 DIPLOMA 14152 2.73 STPM

Plot data in sequence
Hi, Thanks for the reproducible example. Looking at str(datn) would give you a clue. STATUS is a factor because it contains character values. Factor levels by default are alphabetical with numbers first, but you can change those. > str(datn) 'data.frame': 36 obs. of 3 variables: $ LEVEL : Factor w/ 4 levels "DIPLOMA","MATRIC",..: 1 1 1 1 1 1 1 1 1 4 ... $

Ogg Vorbis questions
Hi, I'm currently working on a paper describing Ogg Vorbis. It is not finished yet. Mostly the decoder is being described. If you have any comments, please send them to me. See: http://www.turbocat.net/~hselasky/math/vorbis/files/ Then I have a question about the function "bark_noise_hybridmp()" which is used in the encoder. Can someone describe what the function does in

Speex for sampling freq >48KHz
Hi, I chose speex initially because i had some work in VQ on speex i.e. modifying split VQ to GMM based parametric VQ and I thought If I train the GMM based VQ codebooks with audio signal and then do audio coding with speex, I probably get a better(smaller) residual signal even with speex. But I couldnt get that. I was trying to get a lossless bitstream by MUXing the speex-bitstream and the

Vorbis Block Diagram
Hi, I have looked through the documentation available from the downloads and the web and haven't yet come across a block diagram which shows exactly how the process of going from a .wav file to a .ogg file works. I suspect it is the same as the mp3 process (with a different psychoacoustic model). I found this document:

[LLVMdev] glibc to LLVM port
Hi guys, on the webpages of your project i have found, that you are trying to port glibc to LLVM (sounds interesting). I am student of Faculty of Informatics in Brno, and currently i am trying to search a theme for my diploma thesis. Do you think that this one could have the scope to cover (serve) as the diploma work. Thanks Regards iankko --- reklama

Understanding of Vorbis coder
Hi I have gone through the document available in the net regarding the Vorbis encoder /Decoder. Based on that i have prepared a understanding document on the encoder/decoder block. I would like to know whether my understanding of the coder is OK. If there are any other additional block /information pl. provide me with the same. Thanks and regards S.Padmashri <HR NOSHADE> <UL>

Possibility of Incorporating a psychoacoustic model in 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.

Impulses
After playing with the vorbis code for a while and doing tons of hacks and analysis on it, I've found it to perform very poorly with impulse signals. The MDCT seems to cause lots of spreading, and it seems to result in much worse impulse performance then mp3. What is the current plan on handling this? Will a smart quantizer be able to avoid it? I've been looking at various ways of

[LLVMdev] some questions and llvm on mac-intel
hi all, my name is Jakob. I am studying computer science in Austria. Currently I am working on an aspect oriented dynamic monitoring framework based on LLVM as a diploma thesis. It is a very fascinating framework. Is there some research funding for LLVM development somewhere? Sadly there is not much for me todo with LLVM in my University here in Austria after my diploma thesis. Are there

Lossy Audio Compression Research
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

Vorbis transform description
OK, into the nitty-gritty, albeit a high-level version. If it sounds like I'm glossing important details, you're right. This discusses only the basic DSP; precise coding, framing, sync, etc, will be in another mail. Vorbis is a hybrid transform domain general purpose audio encoder, like MPEG in some respects (it is rooted in much of the same basic theory). For the most part, the
