Warping audio
Warping is a term used to describe the realtime time stretching of a selected section
of audio. Warping is generally used to correct the tempo or timing of audio.
Adjusting loops to the project tempo using Musical Mode
Audio loops are normally short audio files containing a defined number of bars with
straight beats. These loops can be adjusted to the project tempo by using the Musical
Mode function. Proceed as follows:
1. Import an audio loop into a project and double-click it to open the Sample Editor.
If you open the Definition tab and take a look at the rulers, you will see that the
project tempo grid (upper ruler) and the grid of your audio (lower ruler) do not
match.
2. From the Algorithm pop-up menu on the toolbar, select the algorithm preset to be
applied during realtime playback.
For details about the available options on the submenus, see “About time stretch
and pitch shift algorithms” on page 322.
3. Listen to the loop and, if necessary, correct the Bars and Beats values on the
toolbar.
4. Activate the Musical Mode button.
Your loop is warped and stretched automatically to adapt it to the project tempo.
The rulers reflect the change.
In the Project window, the audio event is now shown with a note symbol and a warp
symbol in the upper right corner to indicate that time stretching has been applied.
