Adjusting the timing of a multi-track performance while
maintaining phase relationships
Editing a multi-track instrument, such as a multi-microphone drum kit or a full band, requires a little
more care than editing a solo performance.
When stretching or quantizing multi-track audio, it is critical to maintain the phase relationships of
the original recording. This can only be achieved if the tracks are stretched at the same exact points
in time across all tracks.
AudioSnap provides tools that make it easy to preserve the phase relationship across tracks when
editing beats on individual tracks.
In the following example, you will learn how to use AudioSnap to edit a multi-track drum kit alongside
a piano track. The drum kit was recorded with three microphones (kick, snare, and overhead), each
routed to its own track.
To adjust the timing of a multi-track performance while maintaining
phase relationships
The following figure shows the last three hits of a song. The top track is piano and the rest are
drums: kick, snare and overhead.

As you can see, the drummer has rushed and is not in time with the piano. At the beginning of the
measure, the drummer is in time with the piano. Over the course of the measure, the drummer is
performing a fill and on the next three beats is way ahead of the piano player. You can see how the
