Revert to history states and snapshots

While the Undo and Redo commands restrict you to an incremental sequence of changes, the History panel lets you instantly revert back to any previous change. Use the panel to quickly compare processed and original audio or discard a series of changes that produced undesired results.

History states disappear when you reopen a file, but if you save to Adobe Sound (ASND) format, you can always revert to history snapshots.

Note: When you work with very large audio files, delete unnecessary history states and snapshots to clear disk space and improve performance.
