similar to: DVD 5.1 surround -> ogg ?

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!!!

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

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

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.

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

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

>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

Hello everyone! Please bear with me, I am a complete audio-newbie, and I apologise if I am asking a question that I should know. As most of you all know, DVD's have 5.1 audio, and I want to preserve that in my voribs files. So, to ask the question : Does it support Surround sound? Thank you very much!

Hi all, I'm getting mired in conflicting and dated information, so I think I need to ask this of live humans... :-) I'm essentially trying to create an Ogg file that works like DVD video does. In particular, in addition to the Theora video stream, there will be multiple audio "tracks" (By "track", I mean a collection of channels to be played all at once, but only one

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

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? Thanks, --Richard --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project

I apologize for the terribly long message, but here goes. ------------------------------------------------------------------------------------------------- First, regarding existing tools that I now about. libavcodec and users (e.g. HandBrake): - if there are 6 channels or less, the layout is set by the decoder as per the FLAC specification - if there are more than 6 channels, the layout is

The FAQ says (at its very end): > Does Vorbis support mid/side stereo modes? More than stereo? > > Vorbis has hooks for mid/side stereo and continuous balance stereo, > but the channel mappings for both are yet to be formally specified and > implemented. Currently, Vorbis channels are uncoupled. > This should be updated so that people know how good is Vorbis :) > Vorbis does

When you download the full source for FLAC and read the instructions, you'll see that 'make test' will run the test suite. The instructions warn people that this can bring even a good machine to its knees, and it is not recommended for everyone to run it. I have run it because I have submitted an installer package for Mac OS X, and it seemed prudent to take the time to test

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

Hi, are there any plans for FLAC to implement spatial audio? Or maybe Atmos on FLAC? renatas -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xiph.org/pipermail/flac/attachments/20170810/57a79181/attachment.html>

Hello, I, like many before me, am having an issue with SMB multichannel. I am running Samba v4.10.16 (package is provided by Amazon) on an Amazon Linux 2 EC2 instance. I am aware that SMB multichannel is an experimental feature until 4.15, but the documentation states it is supported so I would like to evaluate it. We have had reports of performance degradation when certain workloads (heavy

I vote for documenting the --channel-map option in the --help I don't like the idea of rejecting a multichannel file merely for mapping, so there should be a documented option plus an error message pointing to the option. This should compare to the WAVE and AIFF errors where the utility suggests to the user how to get the file converted safely. Brian Willoughby Sound Consulting On

Hello Tim and others, Thanks for your help explaining this process on IRC. I wrote out a first draft in the RFC xml format. I have attached the xml (labeled as xml.txt so it will appear inline) and the rendered txt files. Please let me know where I can make improvements. I will upload this draft to the IETF datatracker and send it out to codec@ after addressing your comments. -------------- next
