Hello, I've made some changes in the libvorbis-1.2.3 source code to introduce some functionality I need for a project I'm working on. For compilation, besides including some macro definitions I need to pass to the C preprocessor, and linking with the math library somewhere (and including the source files I've implemented, of course) I've made no big changes in the Makefile or

Hi, Please brace yourselves for some possibly stupid questions. Why are there only 2 codebooks for floors and many more for residue values? What makes the encoding of floor values fundamentally different from encoding residue values? I have a basic understanding of VQ, and looking at the floor decode function, it all makes sense 1) Read the codebook index from the stream 2) Do a

Hi I am trying to build a new decoder in Java, I know there are a couple of java decoders already but they don't implement the bit of the spec I am having questions on Question 1) In section 8.6.2 it mentions "However, it is also possible to set [residue_begin] and [residue_end] to specify a range partially or wholly beyond the maximum vector size. Before beginning residue decode,

I found this sentence in the Ogg format specs: http://www.xiph.org/ogg/vorbis/doc/vorbis-spec-res.html "A residue vector may represent spectral lines, spectral magnitude, spectral phase or hybrids as mixed by channel coupling." But where does the spectral phase information come from ? AFAIK MDCT doesn't provide any phase information. And in OGG-encoding, MDCT is taking place a few

Hi Jean-Marc, For the residue in the echo_cancel function I pass in a pointer to an array of floats. First I used an array the size of the framesize, but I discovered this causes crashes because the echo_cancel funtion writes framesize+1 floats to the pointer. I find this plus one strange, since almost all things are exactly the framesize. Is this an error in the echo_cancel function or simply

Dear list, I wonder if the flac encoded file has a great amount of bits due to the residue. I mean, what percentage of the flac file has information of the residue? Is this sequence represented by more than 80% of the flac file? On the other hand, which is the value typically adopted for the parameter "n" in the Rice coder? I know these results depend on the input wav file, but I

I've been using the rc2 releases of Vorbis for a while now. I've been in the process of making digital copies of a bunch of my music, and I keep getting this "residue bit usage" message when oggenc finishes. I'm trying to encode data from an audio CD at 160bps, and it always seems to get booted back down to ~128 bps with this residue bit ussage message. Again, I'm using

Hi, What is the required size of the echo residue buffer in speex_echo_cancel function? The mdf.c source would suggest that it's frame_size + 1, while preprocessor.c source claims it's frame_size. Bug? Or am I missing something? I am using 1.2beta1. Thanks, Gregg

Hi All, I have a doubt in Vorbis coding. It is said, the encoder subtracts the floor from the MDCT of the data to get the residue. But in the decoder, the 'dot product' of of the floor and residue is done to get back the data. If subtraction is done at one end, addition should be done at the other end. What exactly is 'dot product'? Can you name the function in the decoder

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, it seems to me as if all vorbis-files only contain floors of type 1 and residues of type 2. Is it possible to "force" the encoder to somehow create a vorbis-file with the other floor and residue types?

Yes, I followed The World Institute for Mental Health recommendation. :) But I think the problem might still present

Of interest to some on the list. Anyone familiar enough with Java to know how we go about detecting/using/incorporating an external Jorbis build into the Cortado jar ? Or are we supposed to download sources into our tree and build the whole ? ---------- Forwarded message ---------- From: Hans de Goede <hdegoede at redhat.com> Date: Thu, 04 Nov 2010 15:31:31 +0100 Subject: Merging jorbis

Dear all, I am trying to make a series of waffle plot-like figures for my data to visualize the ratios of amino acid residues at each position. For each one of 37 positions, there may be one to four different amino acid residues. So the data consist of the positions, what residues are there, and the ratios of residues. The ratios of residues at a position add up to 100, or close to 100 (more on

Hello again, I am trying to create a color scale plotting the hydroathy index (y-axis) versus residue (x-axis) - each residue (1-100) has a value between 0-1. I've been trying to create a scale where: 0-0.499: increasing intensity of red 0.5- yellow 0.51 - 1 increasing intensity of green. THis is in lieu of a line graph. I'm not sure which type of plot to begin with - I attempted to

Dear All, As i have understood it , the Huffman codebook uses a huffman code present in the bitstream ( lets us say it is decoding a floor 1 Y value using the specifed codebook number ) to walk through the huffman code book tree till it hits a leaf node which is nothing but the entry number. If we consider our floor 1 Y value example , this entry number is directly being used as the Y value.
