The Sample Editor
Flattening realtime processing
Proceed as follows:
1. Select the audio events that you want to process.
2. On the Audio menu, open the Realtime Processing submenu and select the
Flatten command.
Provided that the time stretching factor is not outside the range of 0.5 and 2, a
dialog opens where you can select an algorithm for the processing.
If the audio has been transposed, the dialog also contains the “Formant
Correction” option. You can activate this, for example, if you want to avoid a
“chipmunk voice” effect.
3. Select an algorithm preset and click OK.
After the processing, any loop that was previously stretched in realtime or had
been pitch shifted will play back exactly the same, but Musical Mode will be
deactivated and the realtime pitch shifting will be set to 0.
Ö Instead of the Flatten menu command, you can click the Flatten button on the Process
tab of the Sample Editor.
The audio clip is now like any standard audio clip before applying realtime processing,
i.
e. it does not follow tempo changes. The flattening processing function is best used
when you have determined the tempo or key of a project. If you want to adapt the
audio to a new key or tempo after flattening, it is better to revert to the original audio
clip rather than to process the already processed file again.
Selecting an algorithm for the flattening
When you flatten the realtime processing, you can use the MPEX 4 algorithm or the
Realtime algorithm to process the audio. The MPEX 4 algorithm may produce better
sound quality than the realtime processing. The Realtime algorithm corresponds to
the algorithm preset selected on the Sample Editor toolbar. For a detailed description
of the available presets, see
“About time stretch and pitch shift algorithms” on page
322.
Ö If you introduced VariAudio pitch modifications, the MPEX presets will not be available
and the algorithm preset “Standard – Solo” is used automatically.
The Realtime presets can be selected from the Algorithm pop-up menu on the
Sample Editor toolbar, see
“Selecting an algorithm for realtime playback” on page
340.
In the Pool, you can select an algorithm for several selected clips at a time.
Unstretching audio files
By selecting “Unstretch Audio” from the Realtime Processing submenu of the Audio
menu, all realtime time stretching (by sizing or by warp markers) is removed.
Ö Note that realtime transpose (in the info line) and Musical Mode will not be removed
by this.
