similar to: what is max and min bitrate supported in OggVorbis?

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

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

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.

Hi, I think that the introduction of the lsp_look lookup array isn't ideal and found a better change that can be applied. in floor0_map_lazy_init() you can replace look->linearmap[W][j]=val; by look->linearmap[W][j]=vorbis_coslook(M_PI*val/look->ln); and in vorbis_lsp_to_curve you then replace float w=vorbis_coslook(wdel*k); ... }while(map[i]==k); by float w=map[i]; ...

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 All, I downloaded vorbis-tools-1.0.1 from http://www.vorbis.com/download.psp for windows platform. It contains workspace for Ogg encoder. It seems Ogg decoder is not there. In Oggdec folder oggdec.c file is there. If I include this file in the workspace it gives some linking errors. Please tell me, how to download the current version of Ogg Vorbis decoder on Windows platform? Best

Is there a archive with a collection of different .ogg files encoded with different settings that can be used to verify compatibility? * Different window size (e.g. != 256,2048) * Much larger codebooks and other extreme cases that are not generated using a standard encoder. * floor0 Regards -- / Johannes Sandvall --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project

Hi, Am trying to run beta4 encoder on a Sun machine. Want to compare floor0 and floor1. Do not have autoconf and automake. Got the encoder to compile with a simple makefile. The only define i am using is NO_FLOAT_MATH_LIB. The encoded file when played(winamp) gives out plain noise. Am i missing any other flags/defs? -Cathy <p>--------------------------------- Do you Yahoo!? Yahoo!

Hi, I have included the oggvorbis encoding and playback stuff in the Linux-Mandrake distro back in August 2000. At that time I put the "nightly CVS" version, which worked just fine. Then on Mon Nov 27 I noticed some RPM's labelled "1.0beta3" on the website so I upgraded with these ones. Since then we have had some serious problems in encoding: approx 20% of the WAV

Hi All, I need some clarifications regarding the mismatch I found in the code and the specification. (a) In the specification, the bark(x) equation is given as: bark(x) = 13.1 atan(.00074x) + 2.24 atan(.0000000158(x^2)) + .0001x whereas in the code it is given as: #define toBARK(n) (13.1f*atan(.00074f*(n))+2.24f*atan((n)*(n)*1.85e-8f)+1e-4f*(n)) Which one of these is the proper one ? (b)

Hi all, I'm busy doing optimizations for vorbis. Don't have time for it, but still doing it :-) Some suggestions: there are some double function names: forward/inverse pack/unpack look/free_look/free_info and maybe more. If they were renamed to time0_forward etc. profiling would be a lot easier. Oh, and add -fno-inline to $PROFILE in the Makefiles (or configure). Most expensive

Hi, I need another clarification regarding the standard. In floor0 header decode (setup), the point no.7 says that if any of [floor0_order], [floor0_rate], [floor0_bark_map_size], floor0_amplitude_bits], [floor0_amplitude_offset] or [floor0_number_of_books] are less than zero, the stream is not decodable But as we see, all those values are read as unsigned integers. Now I'm not able to

Hi, I am not sure to report this as a bug. so mailing to the list. I have sshd(openssh3.5p1) server running on my router and when i run tcpjunk to that port, sshd gets killed after some time 192.168.71.1 is my sshd server and 192.168.71.4 is my client from where i send my dos attack This is the tcpjunk command i gave to the ssh server #tcpjunk -s 192.168.71.1 -p 22 -c req -i 100 req session

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

Hi, Please redirect me to the right mailing list if this is not the correct one. I would like to know what stable version of OpenSSH added support for IPv6 for the first time ? Thanks in advance, Ravindra

Hi, We are working on Oggvorbis encoder porting on embedded platform. Where can we find good test vectors (wav files) for testing OggVorbis encoder? Does anybody have any idea. Parul Embedded Engineer Einfochips Ltd

Dear Sir, I am a DSP Engineer working in the field of Audio Standards and general Signal Processing Algorithms. I am very much interested in knowing the algorithms which make OggVorbis a reality. Kindly send me the link which will lead me to the algorithm description or pseudo-code. Thanking You, Sincerely, Tom Xavier. <p>--- >8 ---- List archives:

Hi, Have anybody worked on converting OggVorbis encoder floating point code to fixed point (32 bit or 24 bit). How do you handle _vp_noisemask in that case where precision goes upto 40 bits. Any help available? Parul Embedded Engineer Einfochips Ltd

We are working on OggVorbis encoder. In the porting effort we are trying to convert it to fixed point code (both 32 and 24 bit fixed point). Now the issue is how we do the testing. What should be the criteria for our testing. Does anybody has any idea how compliance testing (i.e. some objective tests) is done at encoder side? What is the criteria of testing at the encoder side? If anybody
