Set (normalise) them to exactly the same level, ensure both are set exactly at the same time, invert one of them then play the song.


If you ever attempt to use this method you indeed need to make sure the two are exactly in time.
By 'invert' I think Teunis means to reverse the polarity of both tracks.

This also means both would need to be at the same volume (Normalizing would get them close but other ways exist).

The theory is that what is in one track sending a negative value would cancel out another track sending a positive value.
This has been a proven technique, but understanding the mechanics can be important.
Get them out of time a little and the results are wrong (usually results in a noticeable phasing).
Having one a little off on volume can also skew the results .. but the science is pretty cool to know. smile

Interesting application of the theory Teunis! I wouldn't have thought of this.

I do not work here, but the benefits are still awesome
