Well, I seem to be having a problem with encoding multichannel wavs in flac, the file that I am trying to encode is a 48khz 16 bit 5.1 wav.  I use this commandline in flac: flac -8 --channels=6 "input.wav" "output.flac" it gives an error and will not open the file to encode, it says, "ERROR: unsupported compression type 65534" I really really don't want to use wma for this so I hope someone will be able to help me.  Basically, the reason why I am doing this is because I am going to create a listening test of about 60 different samples comparing DTS and DD at their respective bitrates for a dvd, 448kbps and 768kbps.  I am going to use surcode and soft encode to make the DTS and DD.  The originals need to be in flac and everything else is going to be in flac once it is encoded to the appropiate format and then decoded back to wav.  Hope someone will help,

I think that your multichannel wavs are wave_format_extensible format which is not supported by FLAC.
If you can play with WindowsMediaPlayer, it is wave_format_extensible format file certainly.

winamp diskwriter can convert your wavs to the format supported by FLAC.

I tried 96k/24bit with FLAC and couldn't get the waves to load. Does FLAC support high resolution 5.1 like that, or is WMA lossless the only one?

Thanks,
Mike
