@Dhilung@moyix Ironically, most of us would use a computer to check if this other computer was correct. And interestingly we trust the simple one over the complex one.
@keunwoochoi Cool, glad to help! Another issue is that all the stems together still has some artifacts, which seems suboptimal for e.g. remixing applications. Is there some advantage that the masks don't sum to unity? Is it naive to think that "other" can just be the residue?
@Strategictaper @BossaTova It would be cute if the filtered parts of the signal actually got stuck and not just dissipated as heat. It could have a led for "full" and then you had to flip a switch to empty that bin thru your speakers.
