Hi, I believe that line 22 in window.h (vorbis\lib current CVS) that currently reads: extern void _vorbis_apply_window(float *d,float *window[2],long *blocksizes, should read: extern void _vorbis_apply_window(float *d,int *window[2],long *blocksizes, ie., 'window' should be int * and not float *. <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Hello, I have a few questions about the block size in ogg vorbis 1. The allowed blocksizes are powers of two between 64 and 8192 Samples. As I understood , there are fixed sizes for long and short blocks . The encoder can pick any allowed value for long blocks and onother value, that must be smaller or equal to the first one, for short blocks. On which base does the encoder choose the size for

Hi. I've some question about audio-stream of OGM. I know some encoding tools, such as headac3he or BeSweet, can encode 5.1ch AC3 files into 5.1ch vorbis files, but I couldn't find any decoding tools which can decode 5.1ch vorbis files properly. Current Tobias's Ogg Direct Show filter 0.9.9.1 (and its libraries) doesn't support decoding 5.1ch vorbis, right? And if so, how can I

Hello, In one of my recent assignments, I was asked to develop a ogg player. I am not able to find the right repository of the source code. There are few repositories on vorbis but I am not clear which one is the right one for Windows environment. If somebody has successfully compiled any ogg player ever, his ideas will be helpful to me. In one of the code set, I was able to compile the

To those who have reported having a problem selecting real number quality settings, could you kindly test the new compile you can d/l from: http://homepage.ntlworld.com/jfe1205/testXPd.ZIP and report whether this resolves the problem. No major changes, but I regularised a number of type casting discrepancies that could have been causing a problem. I'm sorry to have to ask for help on this

Are the ogg/vorbis programs updated to v1.0.1 ? OggDrop for example ?

Hello Martin, > how a number of samples with no defined size is translated into 8, 16, or 32 bit values in my buffer Although I do not know in detail about the actual implementation of libvorbis, most of the decoders should internally produce single-precision (32bit) floating point values, or 32bit integers as the result of PCM decoding. They are downcast to PCM samples with 8bit, 16bit, or

I'm starting in on documenting bits of vorbis (I'ld like to work on low bit rates someday). 1. Can others doing documentation tell me what they're working on? Please e-mail me directly. I'ld rather my efforts were coordinated with yours! 2. In lib/block.c, I do not understand the rationale for the choice of largebound in the case of vd.W being a short window (vd.W==0). The

I am deeply sorry about the corrupt message just being sent; there seems to have been a compatibility issue with my mailer and my browser. This is an identical copy of the previous message: Hello Martin, Vorbis encoders are lossy, which is in a sense equivalent to converting the sample size of the raw PCM stream into something that would result in the desired bitrate. The "sample size"

Hi, Just to confirm: for blockSizes of 256 and 2048 (0 and 1 respectively) the number of sample inside this audio packet will be acording to table below: LastWind ThisWin Samples 0 0 128 0 1 576 1 0 576 1 1 1024 Correct?? thanks a lot. --- >8 ---- List archives:

Hi, I am using libvorbis-1.0.1 and I am trying to debug the example decoder (examples/decoder_example.c) using gdb. I have compiled the source tree for debug and can single step through the program. However i am facing the following problem (which I think is more of C than vorbis) 1. after single steppig I finally arrive at the function shown below (in file lib/info.c) static int

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.

Tonight's commit is a round of psychoacoustic improvements and bugfixes. (Basically, a week spent with plotting tools making sure each and every element of the process was functioning as expected. Found some nasty little tuning mistakes in there). Things are currently tuned to approximate 128kbps. If you find any samples that don't sound good at this point, let me know. What's

Hi, Can someone tell me how to compile the vorbis dlls under Windows? I've already got to the part, where I downloaded the sources from CVS.

If you are after a 1.0.1 SDK built in the same format as 1.0, and if the current CVS is firm for the release, then you can download the SDK from: http://homepage.ntlworld.com/jfe1205/OggVorbis-win32sdk-1.0.1.zip This is built from the current CVS using MSVC++6 SP5. If this helps speed up the release, great, otherwise, no problem, it kept me amused for a few minutes!! John <p>--- >8

Hi all, Q1: The source defined this structure in the psy.h file: typedef struct{ int eighth_octave_lines; float preecho_thresh[4]; float postecho_thresh[4]; float preecho_minenergy; float ampmax_att_per_sec; int delaycache; } vorbis_info_psy_global; However, the file psytune.c makes this declaration: tatic vorbis_info_psy_global _psy_set0G={ 0, /*

Hi, I am attempting to port ogg-vorbis to the iPaq H36xx (see http://handhelds.org). Since this device uses an ARM chip, no floating point. Now the port was easy and worked fine, except that all the fp ops were emulated, making it very very slow. So I thought I would try with -msoft-float so an exception doesn't occur on every fp operation. libm had no soft-float library available,

Hi, can someone explain whats the meaning of the two blocksizes in the first header of Vorbis, please? So far I assumed that they meant that 2^b0 and 2^b1 were the only two blocksizes used during the whole encode, but something makes me believe they are not: if b0 and b1 are 0xb8 respectively (that I interpeted as 2^11 = 2048 and 2^8 = 256) I observe 3 different deltas between each couple of
