similar to: Multichannel vorbis.

Hi, As I´ve understood things, the Ogg Vorbis format supports more that two channels (stereo). Is there any tools to encode x sourcefiles into one .ogg file? I am a musican and am thrilled with the ide of makeing music in surround (or in more than stereo). This leads to my next question: is there (developing) any decoders for multichannel oggs to, let us say, 4.1 or 5.1 surround? Wouldn´t it

Hi, Has anyone thought about using the multichannel format as a way of distributing "musician minus one" files? Eh? I hear you ask. Ok. Basically these are multitrack files but you can mute the solo track so you, the musician, can practice against the other "players". You can buy CD's of this nature, but of course, the solo instrument is on one channel and the others on

Hello to the list, and please forgive me if this has already been asked before. (I am new here, you see) The question is really simple: Can I use FLAC to create multichannel files, ranging from 3-channel LCR, through Quad, 4.1 to 5.1 and possibly (later) above? The projects details are essentially this: DVD-Audio, containing MLP Lossless in stereo & surround/multichannel. Video_TS folder

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

I made a few updates to OggPCM2 http://wiki.xiph.org/index.php/OggPCM2 reflecting the latest discussions. Could everyone have a look at it and see if they agree. Otherwise, what do you feel should be changed? Anyone wants to speak in support of chunked PCM? For all those that are just tired of this mess like me, please express yourself in the new spec I created: OggPCM3

>Yesterday I have finished writing the ambisonic pan filter for oggenc. May I ask what this "pan filter" is?

The prospect of people actually putting B-format audio (via the panner or directly input) into Ogg/Vorbis brings an interesting challenge: What do we do with the audio after decoding it? The following sane options exist: A) Simply output the B-format audio B) Produce a downmix 1) Mono. 2) Stereo blumlein crossed pairs 3) Stereo UHJ 4) binaural C) Produce speaker feeds 1) Fully

There is some time now that I reported this issue on the bugtracker: https://roundup.ffmpeg.org/roundup/ffmpeg/issue1325 And this guy, jbr, kindly created a patch that solved the problem. What is needed now for the patch to be included in the SVN? About his patch, there is a remap table that maps the channel order from SMPTE order to Vorbis order. What is this SMPTE order?

All, Progress has been made on the proposed draft spec for integrating ambisonics into vorbis. We are not yet finished (should be soon), but you can see the progress here: http://docs.google.com/Doc?id=df4dtw69_3626qqq6st The issue we have hit now concerns how/who would implement the encoding and decoding in Vorbis Tools. Because ambisonics uses spherical harmonic components, an ambisonic file

I know some floating point DSP chips use a 48 bit float internally, but if there is more than one they are unlikely to be compatible and they certainly cannot be read by standard CPUs without having pull each value apart into

I'm a mathematician and programmer working on experimental surround sound techniques. Some of the ideas I'm working on require dozens of channels. These channels are often highly correlated and are very well suited to compression. I'm new to Vorbis. Does it attempt to address such issues?

Hello, I'd like to understand the use-cases to use SMB multichannel. Especially, if the SMB client and Samba server are talking over the WAN. When does one see an improvement in throughput with multichannel? For instance, does copying multiple files result in parallel copying over multiple connections over the same session? Your inputs are appreciated. Thanks, Madhu

Dear all, I have just implemented a gstreamer plugin for the Speex AEC, but now I would like to extend it to a multichannel echo cancellation I have been searching documentation about that but I could not find it Where it is? If it doesn't exist? Could you add a short example showing how do you think it should work? or It's "just" necessary to: init the multichannel echo

Hi, I was wondering if it would be possible to do multichannel encoding with CELT. From the documentation & the code I understand that CELT currently encodes mono (1 channel) or stereo (2 channels). I would like to use CELT in a multichannel setup, to encode (and stream) n mono channels. Just n mono channels, not a layout like 5.1 With vorbis I can do this, but vorbis adds a lot of
