I have an SACD disk with DTS audio and I'd like to convert the audio to a multi channel MP3 file. I've read that multi channel MP3 exists but I've never seen it. First, does it really exist? I've demuxed the SACD to get a DTS audio file and I've tried many audio and video converters in an attempt to get multi channel MP3 files but all I can get is 2 channel MP3s. Is there any way to do this? I'm not married to the MP3 format. I just want a format that will play on media players (iPod and WDTV). Is this possible?
