Ok. So here's the archive from the challenge I posted elsewhere.

http://www.septiknexus.com/challenge.zip

It's in a zip format with no compression used so the files haven't been altered. I set them up as loops so you can seamlessly repeat them. They are loops of 3 sections from "Hotel California" which I figured was a fair track to pick since it hasn't been mastered in the same way dance music is, and there's a full range of frequencies in the song.

When you are listening to the loops, they could be 1 of 3 formats:
1.) Uncompressed WAV (CD)
2.) 320 Kbit Joint Stereo Mid/Side MP3
3.) A mix of both of the above.

I have PM'd the answers to Slav for independent verification. Have fun. :)
