Are there any programs that are able to seperate the channels? -Sound Forge - PC

Subject:Are there any programs that are able to seperate the channels? Posted by: clone Date:4/29/2000 3:09:00 PM I know this doesnt have anything to do with sound forge really, but I was wondering if anyone knows of a program that where you would load in a .wav and it would seperate the channels so you can just edit the vocals or just edit the guitar or something along those lines.

Reply by: Sonic Date:5/8/2000 1:43:00 PM Unfortunately, this type of functionality still falls into the 'holy- grail' category in DSP circles. A good deal of research has gone on over the last few years for decent source separation algorithms (try 'audio source separation' in your favorite search engine), but current technology has produced mediocre results under strictly controlled environments. Older methods use simple mixing algorithms and EQ but rely on assumptions about the mix and usually apply only to sources mixed to dead-center in a stereo mix. Newer methods use things like time- frequency representations and neural nets. Quality-wise, most of this work is still in its infancy. Typical artifacts like reverb tails, smearing from chorus, etc. abound. Some products claim to give 'ideal' results, but such claims are generally attributable to marketing smoke-and-mirrors. I have yet to hear a demonstration of pro-quality source separation that is applicable in a general sense. Of course, I could have missed some miracle breakthrough...If you find anything particularly impressive, I'd love to hear about it.
