Time for some stretching exercises

December 8, 2006


Objective: Stretch audio to fit tempo, and manipulate the timing of individual beats.

Background: Sonar 6’s AudioSnap feature (in both the Producer and Studio editions) includes several tools that can work together or separately to stretch audio in multiple ways; we’ll cover two such ways.


1. To stretch a clip to fit tempo, first select an appropriate Snap value to which you will stretch the clip.

2. While holding down the Ctrl key, slip-edit the end (or beginning) of the clip to the desired measure boundary. A band along the bottom indicates how much the clip was stretched, as a percentage.

3. To alter the position of a note within the stretched clip (or a non-stretched clip), right-click on the clip and select “AudioSnap Enable.”

4. Transient markers appear on the clip, and the AudioSnap palette appears, but no adjustments need to be made to alter individual beat positions.

5. Move the cursor over the transient marker that indicates the start of the note you want to move. The marker becomes thicker and brighter.

6. Click (the transient marker changes colors) and drag to the new position.

7. If there is no transient in front of the note you want to move, click just before the note, then click on the Insert Transient Marker button.



-One really good use of moving individual notes is to lead or lag specific beats to change the “feel” of a loop.

-Sonar 6’s stretch algorithm can often give better audio results than using “acidization” techniques; try both and determine which one sounds better.
