Audio Delay & Tempo

Audio Delay & Tempo gives sound technicians and musicians fast, deterministic delay values. Calculate stage or speaker delay from distance and air temperature, with meters or feet. Switch to tempo mode for whole, half, quarter, eighth, sixteenth, dotted, and triplet timing. Every result includes milliseconds and sample offsets for 44.1, 48, and 96 kHz. Save frequently used setups and share the result. No account, advertising, analytics, tracking, or server is used. The app interface supports English, French, German, Spanish, Italian, Japanese, and Brazilian Portuguese. Find delay times and Hz for 21 note values, tap to find your tempo, copy exact values, and recall saved setups. A cleaner interface now supports light and dark mode.
