similar to: Does Ogg Vorbis support 5.1 surround?

Hello all Could you please tell me if and how Vorbis is used for the audio in DivX? Is it still encapsulated within ogg container format in DivX or does DivX contain raw Vorbis encoded packets? Any clues or pointers would be helpful. Thanks & regards ~previr

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have an AVI file (~900MB) that I want to convert to OGM format, with a ~ DivX 5 video and uncompressed AC3 (5.1ch) audio stream. Nandub doesn't want to compress the audio, so I was wondering if anyone could recommend a (Windows) tool to help. Thanks for your time! -Chris - -- "Everyone has to find their own reason." ~ -Cloud,

Hi, We would like to announce the first release of the Speex project. Speex (http://speex.sourceforge.net) is an open-source (LGPL), patent-free compression format allowing an alternative to expensive proprietary codecs. Unlike Ogg Vorbis which compresses general audio, Speex is designed especially for speech. For that reason, Speex is meant to be a complement to Vorbis. Since it is specialized

An issue was raised at <http://forum.doom9.org/showthread.php?p=1728923#post1728923> - FLAC uses WAVEFORMATEXTENSIBLE_CHANNEL_MASK tag to describe non-standard layout, but it isn't mentioned anywhere in FLAC format. Channel assignment is described at <https://xiph.org/flac/format.html#frame_header>: "Where defined, the channel order follows SMPTE/ITU-R recommendations."

Hi all, Yes, it's true. A new version of rehuff, the tool that losslessly compresses Vorbis files: one that is easy to compile, and that works with newer-than-two-years-ago streams, too! On 1.0 streams, you get about 3% size reduction, and the headers get _much_ smaller (which helps for fast-start network streams). Building it should be easy (you might have to add some -I and -L for

It obviously would be nice to have such a mode available, for e.g. DVD audio compression. Apparently, the list doesn''t tell me too much about it. My questions are: 1. What is the current status of the 5.1 channel coupling in Vorbis? 2. If I''ll be interested in participation in its development, what is the recommended reading? -------------- next part -------------- An HTML

Hey folks, As I understand it, the vorbis codec had support for a channel count > 2, but that it didn't explicitly state the channel binding for channels 3, 4, ... . I'm assuming that with enough fiddling, it would theoretically be possible to use a 5.1 stream encoded into vorbis. From what I know of the CELT codec, it handles either only mono or stereo. Is that correct? -- Kip

>Yesterday I have finished writing the ambisonic pan filter for oggenc. May I ask what this "pan filter" is? I made some tentative suggestions for coupling Ambisonic B-format in a post "Vorbis Ambisonic coupling" on 4feb07 I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format. Would anyone like a

Hi I recorded many hundred of CDs in Ogg Vorbis with exactly the same parameters. I can see very big difference of volume level from one CD to another when I play it onto my computer or my portable device (iRiver HP120). So, I have two questions : * Is the reason of this fact is that it's depends on the volume level at burning time of the original CD ? If not, what is the reason ? * Is

This may not directly be a vorbis topic, but it could have some VERY serious implications for open source development. I read this morning on the doom9 site about the "Security Systems Standard and Certification Act." I not a lawyer so I'm just going by doom9's interpretation. Here's an excerpt from doom9: "Should it pass kiss your rights as a consumer by bye. As a side

Hi, I've been running some simulations for a while and the performance of R has been great. However, I've recently changed the code to perform a sort of chi-square goodness-of-fit test. To get the observed values for each cell I've been using table() - specifically I've been using cut2 from Hmisc to divide up the range into a specified number of cells and then using

Hi there, I've been searching for a while now, for an answer, whether or not EAX and surround sound is supported in wine. And all I've found are contradictory opinions. So, still I can't get neither to work, and I hope, this is the right place to ask for help. [Wink] As I understood it, wine should be able to play surround sound, when alsa is able to do it.

Hi, I bought an iRiver HP-120 which can read ogg files (via a hard drive). Many people experiment that reading ogg file decrease the baterry charge more quickly than with mp3 at the same bitrate. The only raisonnable reason of that mysterious thing is that reading ogg file is not sequential onto hard drive, and the hard drive head must move more than for reading an mp3 at the same quality, and

Hello, I'm new to this list, and I would like to know about the current status of FLAC and surround formats (5.1, 7.1). I know it is possible to compress interleaved multichannel files with FLAC, but does it in any way have any multichannel matrix, that collects common information from all channels and use this when compressing? If not, wouldn't it be a great idea to have this feature!!!

Hi everyone, Over the last two weeks or so, I've been thinking about how to add surround sound to Ogg -- and more than that, to do it in the best way possible. With this in mind, I started considering using Ambisonic surround sound. The advantages of this format are considerable: a) It was developed in the early to mid '70s, so the patents should be expired by now.
