5. Select a Stretch percentage range from the pop-up below the slider.
This determines the maximum stretch range with the slider. If you for example
select 4.2%, you may visually stretch the waveform ± 4.2%, with zero stretch
in the slider’s middle position.
6. Move the slider and try to find the position where as many as possible of
the vertical lines are fully drawn (matching).
To reset the slider to middle position (zero stretch), hold down [Command]
and click anywhere on the slider.
● As you move the slider, you will note that the waveform image is stretched
(slider above middle position) or contracted (slider below middle position).
This is only a visual help for you, to make it easier to find a match, and does
not affect the actual Audio Event at this stage.
7. When you have found the best possible match, pull down the Audio pop-
up menu and select Slider to Time Stretch.
This instructs the program to process the Audio Event using the Stretch factor
set with the slider.
8. When this is done, your Audio Event will play a new segment, time
stretched to fit the playback tempo.
Quantizing Audio
● This text describes advanced audio quantizing of any type, Groove, Iterative
etc. If all you want is quantizing to a certain note value, see page 259.
For this to work, Match Points should be inserted through the whole Event, and
preferably evenly distributed, for example on every quarter note. It is possible to
create a tempo map for an Audio Event with a lot of “syncopated” Match Points,
but this will require you to insert and move Meter Hitpoints by hand (see step 5 be-
low).
● Do not put Match Points too close! This might give rise to large stretchfactors
when quantizing, which in turn may produce a result that is not musically de-
sirable.
1. Activate Master on the Transport Bar.
2. Set Snap to the note value that separates the Match Points.
In our example, this would be 4 (quarter note).
3. Set the Left and Right Locators so that they encompass the Event.
