Delay & Reverb Pro
BPM, Tap Tempo & Setlist
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn BPM into delay timings in ms and Hz, compare musical reverb suggestions, save presets and songs, then move through one setlist in Stage Mode.
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.
