Hi, we have a speech recognizer here that gets some of its input from a microphone array. To the point we used shorten for the archiving of the material, but since we want to change the license of the speech recognizer to gpl we are searching for an gpl alternative (like FLAC). It seems to be pretty good for our needs (24bit rather than 16bit in shorten and so forth). The only problem is that our microphone array has 64 channels and FLAC apparently supports just up to 8 channels. So my question is if it would be possible to change that to support at least 64 channels maximum. I am willing to assist in the programming part, but since it seems that this would also lead to a format change the whole thing also depends on what you say about this. If it is not possible to change the number of channels supported, do you know an alternative?

I don't know of any lossless codec that supports that many channels per frame. Josh __________________________________ Do you Yahoo!? Yahoo!
