Hora Signature & Tempo

BPM ↔ ms-per-beat, plus bar / phrase length in seconds for any time signature, and a table of common note durations (whole, half, …, triplets, dotted) for delay / echo / reverb pre-delay calculations.

Reverse mode

Enter song length and bar count to get the required BPM (BPM = beats / seconds × 60).

Examples

• 120 BPM → quarter = 500 ms, dotted ⅛ = 375 ms (classic dub-delay feel)
• 3 m 30 s, 64 bars, 4/4 → 73.1 BPM
