Elastic Audio provides real-time and non-real-time (rendered) Time Compression and Expansion (TCE) of audio. Tick-based Elastic Audio tracks actually change the location of samples according to changes in tempo. The audio stretches or compresses to match changes in tempo. Elastic Audio also provides high-quality non-real-time clip-based pitch shifting.

Elastic Audio uses exceptionally high-quality transient detection algorithms, beat and tempo analysis, and real-time or rendered TCE processing algorithms. Elastic Audio lets you quickly and easily tempo conform and beat match audio to the project’s Tempo ruler. It also provides an unprecedented degree of control over transient detection and TCE processing on an event-by-event basis.

With Elastic Audio, Pro Tools | First analyzes entire audio files for transient “events.” For example, an event can be a drum hit, a sung note, or chord played by a guitar. These detected events can then serve as control points for “warping” the audio. Pro Tools can warp (TCE) audio events automatically, such as when automatically conforming audio to the project tempo or quantizing audio events, or you can warp audio manually using the standard editing tools with the audio track set to Warp view.

Elastic Audio is useful in several common workflows: working with loops, correcting performances, remixing, beat and pitch matching, and sound design and special effects.
