For source-separation algorithms, most researchers have started with mixtures where the separate tracks are completely known -- i.e., the "ground truth". Then it's just a matter of comparing the separated signal to original signal. The rms difference between the two can be computed, for example. Judging the quality without knowing the original tracks would perhaps be best done by human juries, although I know there are programs such as PSNR, PAQM and PEAQ available. I think human perceived quality would be the best in the long run, although if a program could match this perception, it would certaily be a lot more efficient.
