Useful timing math, without interrupting the music.

BeatTiming is a collection of free, focused tools for musicians, producers, DJs and audio engineers.

Why it exists

Tempo-related calculations are simple but repetitive. BeatTiming keeps the tap counter, note durations, delay times, reverb timing, LFO rates, arrangement duration and sample math in one fast place.

How calculations are handled

The calculators use standard relationships between beats, time, frequency, pitch and digital audio. They run locally in your browser. The site does not need a microphone, file upload or user account.

Calculation method and accuracy

Each calculator uses a deterministic formula with documented assumptions, validation ranges and display rounding. Automated checks cover boundary cases and 50,000 randomized calculations across note duration, frequency, bar length and varispeed relationships. Results are intended to be precise mathematical references; musical choices such as reverb decay still need to be judged in context.

Designed to stay predictable

The core tap surface and calculation formulas are intentionally stable. New utilities may be added, but existing tools are designed to remain familiar to returning users.
