Disclaimer: I'm speculating on much of this, and would love it if somebody with more knowledge of the various specs could show me I was wrong.

I think that sending to the receiver will be the hard part. I wonder if it's possible to send a 6-channel WAV directly to a receiver... if not, the problem is (as you say) that the MP3 will have to be decoded and then re-encoded to some format the receiver understands (AC3 or DTS? Possibly not practical; I don't know what the licensing or processor power issues are). Decoding: according to Fraunhofer, "decoding the six channels needs around three times the processing power of decoding stereo MP3". I have no idea if the SB2/3 could support that. Fraunhofer also claim that an MP3 Surround stream can be sent over S/PDIF just like MP3. I presume that implies the receiver will be decoding it, and that a compliant receiver would be required for the surround effect (but I'm just guessing). ... Just checked the specs for my receiver, which can handle AC3 and DTS -- there's no mention of multichannel PCM support (and indeed it seems to be that PCM data is forced to be stereo). That's just one receiver out of many, so maybe 6-channel PCM is still viable. I suspect that the best way to get this to work would be if a receiver supported MP3 Surround files natively, and could be passed the data over S/PDIF. -- smst ------------------------------------------------------------------------ smst's Profile: http://forums.slimdevices.com/member.php?userid=752 View this thread: http://forums.slimdevices.com/showthread.php?t=28112 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
