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

Hi, a newbie query about a potential bug in VorbisLib (I tried using bugzilla with no success): My problem is that I encountered a divide by zero exception that I tracked down to bark_noise_hybridmp() in PSY.C. I don't pretend to know what bark_noise_hybridmp() does but there are a few instances of the following in that routine: D = tN * tXX - tX * tX; R = (A + x * B) / D; When I

I wrote to the list earlier about optimizations of the tremor. Specially replacing the IMDCT with a N/4 FFT. The report is available here: http://www.sandvall.nu/thesis.pdf Short summary: Optimization of the Tremor code under 50kB for a "split" decoder version. ~44 MIPS. Huffman highly unoptimized. IMDCT ~ 8 MIPS. Quick overview of the

Hi !! <p> I am just now reading Vorbis I specifications . I ahve some quries in that regading overlap add and sqaure polar mapping . I am writting this mail with the hope that ,some one will resolve my quries. <p> 1. After IMDCT , to remove the aliasing , we do overlap and add . For that the window should have following properties -------------> hk =

Hello everyone, the code is slowly getting a little bit messy, but at least I've managed to tweak a lot of performance out of my Vorbis player for Flash. I did several improvements to the Huffman decoder by eliminating function calls and managed after a while to create an AS/haXe hybrid player. The haXe compiler definately produces much more efficient bytecode (at least in some

Hi On http://www.xiph.org/ogg/vorbis/doc/vorbis-spec-intro.html there is a link to a document titled 'The use of multirate filter banks for coding of high quality digital audio' that explains window functions for iMDCT. I would very much like to read that document, but the link is broken. If someone would send me the document or a working link to it, I would be very happy. Thanks in

Hello everyone, I recently stumbled upon an issue in the encoder of the v1.0 SDK. At the end of each encoding session a divide by zero (D=0) happens in bark_noise_hybridmp (psy.c:642). This causes a crash on Win9x systems (WinNT seems to handle this fine by using infinite as the result). My encoding code is almost identical to the encoder_example, so I'm reasonably sure that this is not a

Hi Ralph, Again, thanks so much for doing all this! Plus thanks to all the folks who contributed to the new release! Quick clarifying question -- Isn't CVE-2018-10392 (looks like it’s fixed in https://gitlab.xiph.org/xiph/vorbis/-/issues/2335) also included in new version 1.3.7? If so can you please add it to release notes? (I asked the same question in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I want to encode wav file into fixed window length vorbis file. I don't know if "window" is good name for that, but i mean MDCT buffer size. This buffer is passed to mdct_backward() as "in" and it's size is determined by "init->n" variable which is also passed to this function. So, when I say "window

Lancer 20060302 (based on aoTuV 4.51) http://homepage3.nifty.com/blacksword/ Changes: * update to oggenc v2.81 * optimized SSE2 code implementation * bark_noise_hybridmp and seed_curve are inline assembled * modified mdct_forward's SSE optimization * double step bresebham algorithm for render_line, render_line0 implementation

Hi I've got serious problem with my Vorbis-Decoder. The error seems to happen in the inverse Mdct. Before the imdct the values seems to be correct (compared with those of jOrbis (www.jcraft.com/jorbis/)). But after the transformation the values shows a strange behaviour. In [0, blocksize/2] the values are correct, but in [blocksize/2, blocksize] the values are wrong. The difference in

Hello, I'm not quite sure if this is the right list for my questions, please excuse if it isn't. 1. While using vorbislib (Win2K/Borland C++ Builder 5), I'm getting reproducible floating point exceptions at lots of sample rate/bit rate combinations. For example, the original encoder_example.c, with just the initialization line changed to

Hi everybody, after hearing about the new Sound functionality in Flash 10, Arek's performance gain using the new Vector type instead of Array and not at least actually seeing the performance boost he achieved compared to my old Vorbis decoder, I found a few hours yesterday to migrate my old code. First of all: the new PCM playback API for Flash is rather restricted and only allows 44.1

Ok, I wasn't able to track down the original steps to reproduce this issue,s but we believe CVE-2018-10393 is a dupiicate of CVE-2017-14160, both fixed by commit 018ca26dece6. Because of the confusion, I added additional bounds checks to the bark_noise_hybridmp function, which make it clear to local analysis that no for bugs in this class are possible. This change is in commit a9eb99a5bd6f.

Using Debian 4.0. I want to create one Share (eg. Files) and have subdirectories for each department. This is so that users only have to mount one share. So it looks something like this: Files - Accounting - Human Resources - Enginnering - etc Using Samba how can I give subdirectories different permissions using Active Directory. Would this be done by creating corresponding

Hi all, We are organising another open source search social evening in London on Wednesday the 28 July. As usual the plan is to get together and chat about search technology, from Lucene to Solr, Hadoop, Mahout, Xapian and the like - bringing together people from across the field to discuss ideas and ask questions over a quiet drink. For directions to this meetup and for the Meetup.com group

Hello, Please join us Wednesday May 17th for an informal kickoff to openly discuss and formulate a plan to resurrect the Ottawa Asterisk User Group as well as discuss additional topics of interest that impact the VOIP marketplace and may also be included in our collective strategy. We'll also hear from the folks responsible for the Canadian Association of VOIP Providers (CAVP)

This Wednesday, November 26th, the Toronto Asterisk Users Group invites all in the area to join us for a telephony workshop and talk sponsored by Sangoma Inc.[1] Jose Landivar, co-founder of PaloSanto Solutions[2], creators of Elastix, will be running a "getting started" workshop on Elastix, followed by a talk discussing how it differs from other Asterisk-based distributions, and a
