Post subject:  Creating a Minus Track on Mac

Having discovered a lovely air on a CD with a wonderful backing, I would like to learn to play the piece and then be able to play it against a version of the track without the original whistle. I've tried using Audacity and the technique for removing a vocal to create a "karaoke" track but it doesn't seem to work and remove the whistle. Anyone gone down this road and successfully created their own backing track from an original tune?

If the backing track is mainly lower pitch stuff you could make a shelf filter in Audacity and cut off everything above the fundamental of the lowest note the whistle plays.

Thanks. Sounds good. Can you give me more information on how to do that? I'm not that familiar with Audacity.

on the "effects" menu. equilization.

You just draw a curve by clicking and dragging.

You could experiment, or maybe someone knows the answer, but I'm guessing a d whistle is playing mainly above 550 hz (i.e., the d above middle C). Or is it an octave above that -- 1100?

1100

Thanks for the tips. I'll give it a try but am realising the problem with this. The particular track I like has a Low F whistle in it so removing it would mean substantially cutting across the backing instruments. But I should find another track that uses a high D whistle and try it with that.

If it's a stereo recording, you can also try phase-inverting one of the channels then mixing both channels down to mono. Works best if the lead is centered and there's good L/R separation of the rest, otherwise much of the rest may also disappear. But yes, I've had good (or at least usable) results with some recordings.

Thanks MTGuru. That's the initial route I tried and described as "karaoke" when I started the thread. It wasn't particularly successful!!

For the record, a concert-pitch, high D whistle starts at 587 Hz.
