Pitch Shifting
Elastic Audio allows you to change the pitch of audio material without altering its tempo. This is ideal for correcting vocal intonation, transposing melodies, or creating creative pitch effects. To use pitch shifting:
- Select the audio region you want to pitch shift.
- From the “Clip menu,” choose the “Elastic Audio” option.
- Click on the “Pitch” tab in the Elastic Audio window.
- Adjust the “Pitch Shift” slider to raise or lower the pitch of the audio.
Time Stretching
Time stretching allows you to change the tempo of audio material without affecting its pitch. This is useful for syncing audio to video, creating slow-motion or fast-motion effects, or stretching vocal performances to fit a particular rhythm. To use time stretching:
- Select the audio region you want to time stretch.
- From the “Clip menu,” choose “Elastic Audio” option.
- Click on the “Time” tab in the Elastic Audio window.
- Adjust the “Stretch” slider to increase or decrease the duration of the audio.
Time stretching can be applied in two modes: “Beats Mode” and “Samples Mode.”
| Mode | Description |
|---|---|
| Beats Mode | Preserves the rhythmic subdivisions of the audio, allowing for natural-sounding time stretching. |
| Samples Mode | Stretches the audio material by a specific number of samples, resulting in a more mechanical sound. |
Using the Scrub Tool for Precise Editing
The Scrub Tool is an invaluable tool for making precise edits to audio. It allows you to quickly and easily navigate through audio, audition different sections, and make precise adjustments to your edits.
1. Enable the Scrub Tool

Tips for Optimizing Elastic Audio Performance
Elastic Audio is a powerful tool in Pro Tools, but it can also be taxing on your system. Here are a few tips to help you get the most out of Elastic Audio without overloading your computer:
1. Use the Preview Mode
The Preview Mode allows you to audition your Elastic Audio edits in real-time before committing them. This is a great way to experiment with different settings and find the best balance between audio quality and performance.
2. Freeze Tracks
Freezing tracks that you’re not currently editing can free up CPU resources. To freeze a track, right-click on it and select “Freeze.” You can then unfreeze the track when you’re ready to edit it again.
3. Use Offline Processing
Offline Processing allows you to perform Elastic Audio edits without using real-time processing. This is a good option for complex edits that would otherwise overload your system.
4. Increase the Buffer Size
Increasing the Buffer Size can help to reduce audio dropouts and other performance issues. To increase the Buffer Size, go to the Setup menu and select “Preferences.” Then, click on the “Audio” tab and increase the value in the “Buffer Size” field.
5. Reduce the Number of Elastic Audio Clips
The more Elastic Audio clips you have in a session, the more taxing it will be on your system. Try to limit the number of clips you use to only those that are absolutely necessary.
6. Use a Fast Hard Drive
Elastic Audio uses a lot of disk space, so it’s important to use a fast hard drive for your audio files. A solid-state drive (SSD) is the best option, but a fast mechanical hard drive can also work well.
7. Other Tips
Here are a few additional tips that can help you optimize Elastic Audio performance:
| Tip | Description |
|---|---|
| Disable unused plugins | Plugins can consume CPU resources, even if they’re not being used. Disable any plugins that you’re not using to free up CPU power for Elastic Audio. |
| Use a clean session template | A clean session template can help to reduce the number of unnecessary plugins and other resources that can slow down Elastic Audio performance. |
| Restart Pro Tools regularly | Restarting Pro Tools can help to clear out any memory leaks that may be causing performance issues. |
