How this service works
Tap tempo from tap timestamps in ms: mean and median BPM, interval spread and jitter percent.
Output
Returns mean BPM, median BPM, BPM from first-to-last tap, a rounded BPM, all inter-tap intervals in ms, mean/median/min/max/stdev interval values, jitter percent, and tap count — giving a complete statistical picture of the tapped tempo.
Example use cases
Tap tempo for a sampled loop
“I tapped along to a drum loop and got these timestamps in ms: 0, 512, 1024, 1536, 2048, 2560 — what's the BPM and how stable was my tapping?”
Measure live performance timing accuracy
“A drummer's hit timestamps were 0, 600, 1195, 1802, 2400, 2998 ms — give me the mean and median BPM plus the jitter percentage to see how tight their timing was.”
Estimate tempo before syncing gear
“I need to sync my delay pedal to a track — I tapped the beat and got timestamps 0, 480, 962, 1443, 1924 ms. What's the BPM I should dial in, and what's the interval spread?”
Technical details
Endpoint
GEThttps://music-production-calc.x402tookit.com/tap-timestamps?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a sequence of raw tap timestamps in milliseconds and need statistically robust BPM estimates (both mean and median) along with timing jitter analysis — ideal for detecting tempo drift, validating rhythmic consistency, or syncing hardware to a live performance. Prefer this over simple two-point BPM calculators when you need spread and jitter metrics.
Side effects
- Fewer than 3 taps provided — endpoint requires at least 3 timestamps
- More than 200 taps provided — exceeds maximum input size
- Timestamps are not strictly increasing — returns error or degraded result
- Non-numeric or malformed comma-separated values — parse error
- Single-tap or two-tap input cannot compute meaningful intervals
