The Audio Files Conform to Session Tempo button mirrors the corresponding Browser menu command. When enabled, all tick-based audio files with Elastic Audio analysis, as well as REX and ACID files, conform to the project tempo. This lets you play back the project, and then simultaneously preview the selected files in time with the project. The Audio Files Conform to Session Tempo button is only available when a project is open, otherwise it is disabled and grayed out.

When the Audio Files Conform to Session Tempo button is enabled, Pro Tools analyzes any un-analyzed files on preview or import. Tick-based audio files conform to the project tempo during preview and on import. Sample-based files, those where no tempo has been detected, always preview and import at their original speed and duration.

When the Audio Files Conform to Session Tempo button is disabled, any tick-based audio files with Elastic Audio analysis, and REX and ACID files preview at their native tempo.
