Ok, ready to try and save these to WAV with MPT. I asked around and WAV can support what we're doing here, but the real mystery is whether quadraphonic FLACs will work out. Supposedly, FLAC has multichannel support, so this'll be interesting. Once I make FLAC rips of the multichannel stuff (in addition to keeping the stereo mixes for compatibility reasons?) the new Unreal music collection is done.
Edit: Wow, playing around with MPT, this is amazing...I could potentially make my own little mix of Phanton with this! I knew these songs could be edited, but I didn't think it would be this hands-on.
Edit 2: Ok, multichannel FLACs are no problem. Foobar converts it fine, and even converts back to multichannel WAV by default.
Edit 3: Ok, success. Now begins the process of finding out which Unreal/UT songs have multichannel audio and making rips.
QUESTIONS:
1. Is there any easy way of looking at the song opened in MPT to see if it's just stereo or quadraphonic?
2. The original rips in the collection were ripped with XMPlay, 2 channels...but not downmixed, so the extra channels were just lost. Is there any value to keeping these? I can make XMPlay downmix the 2 extra channels into stereo, so I wonder which version (downmixed, or just completely lost) is best for the archive, and if there will be any difference.
