i didn't find anything about tagging flac files as surround files. i think there should some possibility to tell the player how to play a multi-channel file (how to map the different channels to the speakers or if there some decode is needed, like for ambisonic files). any idea how to implement it?

>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

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

Where can I find the Header file or whatever which specifies the "Mapping" flag. In feb - apr 2007, there was a lot of discussion about Ambisonics and Monty kindly stated that Mapping = 1 ; Denotes and Ambisonic file as opposed to = 0 which is 1 speaker/ 1 channel Has this been written explicitly into the standard? Which standard should I be looking at?

WAV puts the rear centre before everything but 'Front left of center' and 'Front right of center'. Are you saying you prefer the extra front channels to to side/rear surround, or that you prefer the MPEG order to the WAVE order? -r

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

Hey everyone, I've added Ogg Opus support to my Adobe Premiere plug-in here: http://github.com/fnordware/AdobeOgg Now I'll add Opus support to me WebM plug-in too. I've got this Opus stuff mostly figured out, but I have a few questions. Here's one: What do the numbers in mapping mean? I see that opus.h refers to the Vorbis channel mapping order, so does mapping in Opus take

It's not like you can't decide to put the LFE channel into "input 3" or "input 5" or whatever set of inputs your sending it to, depending on

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.

Hi Opus list. I subscribed because your discussion on the IETF draft ("Ambisonics in an Ogg Opus Container") was mentioned on the sursound list. I tried Opus for ambisonics more than a year ago. It does works with uncoupled channels (I had to patch the encoder). I don't know what else could be done to optimize support for ambisonics, as I'm not a codec expert. So I think that

when i encode i multi channel file, does flac encode every channel seperatly or does is look for similarities between channels? the documentation says: INTER-CHANNEL DECORRELATION In the case of stereo input, once the data is blocked it is optionally passed through an inter-channel decorrelation stage. The left and right channels are converted to center and side channels through the following

Hi all, My apologies for the confusion ... but I am re-naming this thread again because the proposal doesn't come from Ambisonia. As the founder of Ambisonia I have only been 'mediating' between some members of the ambisonic community ... so it would be wrong to associate the spec with Ambisonia. To clarify. This is what the spec proposes: - that Mapping = 1 means the contents are
