hi i'm looking for information about the multichannel spec. of vorbis. 1/ the documentation specifies that 256 channels are available ( -c 256) ... it sounds very well but how may i specify the original files ??? (i haven't 256 physical entries on my soundcard ... arffff) so is there a way to declare something like oggenc file1.wav file2.wav file3.wav -c3 final.ogg ??? 2/ panoramics are predefined (L, center, R, ...). is there someone who works on a possible way to define % values in the command line (something like oggenc file1.wav file2.wav file3.wav -% 30 50 70 -c3 final.ogg where -% 30 50 70 could be values for the R channel .... or any other better idea) 3/ Documentation about ogg is really well made ... thanx a lot !!! is there anyone who made one on a same way about vorbis (function definitions, ...) because i must admit i'm a little bit lost with the existing one (maybe because i'm french .... arffffff) Note that percent values could be set to indicate the L (or R) value of your pan (balance ) for the specified file i urgently need information. we are trying to adapt ogg vorbis onto a DSP to realize a physical encoder / decoder using multi channels thanx yvan

Of course, you could adapt oggenc to allow the syntax you've described there (or perhaps just adapt the example encoder, that might be simpler).> > 3/ Documentation about ogg is really well made ... thanx a lot !!! > is there anyone who made one on a same way about vorbis (function > definitions, ...) because i must admit i'm a little bit lost with the > existing one (maybe because i'm french .... arffffff)Sorry, we know the vorbis documentation is somewhat lacking. Please feel free to ask questions about any parts of the API, we'll answer as completely as we can (but this would be considered more on-topic on the vorbis-dev list, rather than here). Mike
I take it you want to create a multichannel ogg vorbis file from separate waves? hmm... Does BeSweet work? I remember BeSweet can convert AC3 to multichannel Vorbis or even separate wave files for each channel, but not sure whether you can input multiple waves to make a multichannel vorbis file.

You can > write such a tool in few minutes...Hi thanx you all for answering What i expect to do is not multiplexing then encoding/compression but encode each file and then multiplexe them This is very important for the project we are trying to realize So if nothing is already developped i ll have to do so on my own but for that i need more informations about the existing process yvan -------------- next part -------------- An HTML attachment was scrubbed...
