Hi, In the course of some work which I describe below, I have found a very significant difference between the BARK function described in the Vorbis specification and its implementation in libvorbis. In the specificationhttp://xiph.org/vorbis/doc/Vorbis_I_spec.pdf bark(x) = 13.1arctan(.00074x) + 2.24arctan(.0000000185x**2 + .0001x) In the libvorbis code

Hi Guys, I want to compile libvorbis, but I get this error message if I made a make.

Hi All, I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. I have following doubts: 1) What is min and max bitrate? 2)What is max Audio Packet size ? 3)What is the max size of setup header? 4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 5) What window sizes in Ogg Vorbis are normally

Is there any difference between a ogg file containing chained logical bitstreams and two ogg files with different serial numbers concatenated (for eg: cat on unix)? -cathy <p><p>--------------------------------- Do you Yahoo!?

Hi According to vorbis I spec, there are several configurations. There are 2 formats of floor, 3 formats of residue and 3 look up types of VQ codebook, etc. I think to get all kinds of vorbis file with these configurations but what I have got from network only support some of the formats (Ex. floor1, residue 1 & 2, VQ lookup type0 & 1). I downloaded several freeware vorbis encoder

This is in response to NO_FLOAT_MATH_LIB not getting set on Solaris. The patchlet below - makes configure check for sqrtf(), - defines HAVE_SQRTF if sqrtf() has been found, - uses HAVE_SQRTF in lib/os.h. NO_FLOAT_MATH_LIB isn't used any longer. --- configure.in.orig Fri Mar 30 02:02:35 2001 +++ configure.in Fri Mar 30 02:10:16 2001 @@ -162,6 +162,7 @@ dnl

Do anybody know, from where I can get an Ogg Vorbis File, which uses floor0 coding. I know that the current encoder doesn't use floor0. Anyway, to be fully compliant with the Vorbis Specification the decoder still must be able to decode floor0. I am working on a Vorbis port to a DSP. I want to go sure, that if the need of floor0 decoding will again occur, this also will work properly.

Hello, everybody. I am looking for same Ogg Vorbis file which have 8192 size frame or using floor0. According to the Ogg Vorbis spec, the maximum frame size is 8192. But I cannot find that size of frame in the Ogg Vorbis file. Also I cannot find Ogg Vorbis file using floor0. If you have, pleas open them. Or can you tell me where I can find them? Sincerely.

Hi` I just subscribed to the list and already have a couple of questions ;) I read the FAQ and skimmed through the archives but I'd rather get up- to date information and not rely on what I read in old posts. Are there any games/ mods using Ogg Vorbis? Are there any other tools despite standalone music players using Ogg Vorbis? How fast is decompression? How big is the memory overhead for

Hello I'm working on a fix-point decoder for AOS/Bluebottle - the proprietary OS of ETH Zurich. I've some problems with Floor0-curve-computation: I don't know what the little omega [cos(w)] stands for, line 3 of the official Vorbis documentation. Does anybody knows what this value means? I've tried to get the answer from the jOrbis and Tremor, but both seem to do - among

Hello, I have two questions concerning floor1 encoding/decoding. First I'll ask about the FLOOR1_fromdB_LOOKUP table: what is it's purpose? Is it to convert the amplitude differences between [floor1_Y] values to a dB scale? And, if I'm right with that, here comes the 2nd question: when render_line0 is used to encode floor1, then floor1_inverse2 must be used in decode (in order to

Hello, I was printing some Floor1 X values from a test audio file, and the values that I've obtained look mostly like the following: [23,33,46,65,79,93,111,130,158,186,220,260,312,372,464,556,750,1024] => For long blocks [8,16,33,70,128] => For short blocks Obviously they are not in Hz, so, could someone please tell me what is the unit used? In the specs it's said that the Floor1

Hello, You know, I always worry about the precision and the float constants... and there is a large lookup table in the floor1.c ... and I figure out a way to keep the code size and speed, but to improve the precision at this lookup table. (the difference is small, but audible) Here is the modifications in the floor1.c: tatic unsigned long FLOOR_fromdB_LOOKUP[256]={

Hi guys, I'm trying to compile vorbis-tools with libvorbis-aotuvb5.

Hi, I've just tried Ogg/Vorbis for the first time, and I'm quite impressed with the results. I haven't heard any artifacts in my tests so far, even at -b 112 (but I'm not a trained listener). Thanks for the great work! Now, some (mostly minor) points: When building libvorbis on either a Linux/libc5 or a Solaris system, both with gcc, it failed with undefined references to logf()

Hi, I'm looking for more documentation on the Vorbis bitstream format. The goal for me is to write an optimized decoder using only integer or fixed point math for use on the Phatnoise Car Audio System (see http://www.phatnoise.com). I've already found the info on the Ogg framing system and I've already written my own thing for parsing through Ogg frames (easy). Also, is RTP

Hi everyone, after having an extensive look at the reference decoder as well as the specification documents, I'd like to point out what I think to be some minor omissions/flaws in the latter, and suggestions for correcting them. --- #1: in vorbis-spec-floor1.html, packet decode: Between 14) and 15) a crucial step is missing.

Here is a test case: extern double floor(double); extern double floor_(double); double x = 1.5; double y, y_; void foo() { double y = floor(x); double y_ = floor_(x); } If I compile this for Mips16, it calls the proper helper function for floor_ but not for floor, because the signature for floor in callee info is wrong.
