DelayCalc BPM: Delay & Reverb
KENTA OSAWA
Getting the latest details from the App Store…
Type one tempo and every time-based value for that song comes out at once. Delay times, LFO rates, reverb tails, loop lengths in odd meters, the key after a tempo change, and sample counts. No reopening a second calculator. Dark enough to read in a studio, and every value copies with a tap. ■ Delay & LFO Enter a BPM and every note value lines up with its delay time in ms and its LFO rate in Hz.

Version 2.0.0 · 4 Aug 2026 · 2 months ago
Version 2.0.0 — a lot more of the song's timing, from the same one tempo ■ Reverb (new) Pre-Delay and Total Reverb Time from the tempo, plus Tail Clearance: whether the tail ends before the next hit, as a number. A starting point for keeping the next hit clean. ■ Tempo & Key (new) Playback speed, semitones and cents when a sample changes tempo — and the key it lands on, in Camelot Key with its Harmonic Matches. New duration, sample count and bar fit as well. ■ Loop Length (extended) Bar and loop lengths in odd meters, and now the tempo derived from a known length. ■ Library (extended) Name what you keep, up to 50 setups. Restoring brings back the page and the time signature too. ■ Japanese localisation Units, note values and industry terms stay as the studio writes them; the prose is translated. ■ iPhone, iPad and Mac One purchase covers all three. ■ Also Four areas instead of one long screen, resume on the tempo and page you left, haptics on each Tap Tempo strike, and a lot of smaller display and interaction fixes. Offline, no account, no ads and one purchase — unchanged.
