Bass Track Isolation?

[Mad Russian]

Is there software available that can isolate bass tracks off of recorded tunes? Prefer something that can take an MP3 and extract the bass track?

Maybe you should have a loot at Transcribe:

But what you are asking for is at the limit of technology today, we cannot really "extract" the bass line, we can just filter some frequencies...
