Delay & Reverb Pro

Set delay and reverb timing from the BPM you already know. Delay & Reverb Pro keeps calculations, songs, and a stage workflow together in one focused utility for musicians, producers, and audio engineers.

Delay timing
- Enter 20–300 BPM manually or use Tap BPM.
- Tap BPM averages the latest four accepted taps and ignores intervals under 100 ms.
- View half-note, quarter-note, eighth-note, and sixteenth-note values in normal, dotted, and triplet feels.
- Switch the timing table between milliseconds and hertz.

Reverb starting points
- Compare musical timing suggestions for Room, Plate, Hall, and Cathedral.
- See total time, pre-delay, and decay separately.
- Build reusable custom reverb timing presets.

Reverb values are musical starting points based on BPM. They are not acoustic measurements and do not measure RT60, SPL, or a room.

Organize one setlist
Save songs with BPM, notes, and linked reverb presets. Reorder the setlist, duplicate songs or presets when you need a variation, and move through the show with large Previous and Next controls. Stage Mode keeps the screen awake only while it is active.

Keep a local backup
Export your songs and presets as one backup file, then restore that file when needed. There is no proprietary cloud sync.

Focused and ad-free
Core calculations, taps, songs, settings, and presets work locally. Tap BPM is manual: the app does not listen to your microphone, play music, process audio, or control external equipment. Purchase, restore, review, legal links, and user-initiated sharing may require the store, system, browser, or a network connection.

The app has no ads for anyone. The core calculator remains available without a subscription. Pro Lifetime is an optional one-time purchase that unlocks saved songs, custom presets, the single setlist, Stage Mode, and backup tools. A three-day local trial starts when you first use a Pro feature.
