BPM Calculator

Tap Tempo

Tap along to the beat of a song or a metronome. The calculator measures the time intervals between your taps and averages them to determine the BPM (beats per minute). More taps yield a more accurate result.

BPM to Delay Time

The fundamental formula for converting BPM to delay time in milliseconds:

Delay (ms) = 60,000 / BPM

This gives you the duration of one quarter note. Other note values are derived as multiples or divisions:

• Whole note: 4 x quarter note
• Half note: 2 x quarter note
• Eighth note: quarter note / 2
• Sixteenth note: quarter note / 4
• Dotted: note duration x 1.5
• Triplet: note duration x 2/3

Delay Time to Frequency

To sync LFOs and modulation effects:

Frequency (Hz) = 1000 / Delay (ms)

Delay Time to Samples

For working with sample-accurate timing in a DAW:

Samples = Delay (ms) x Sample Rate / 1000

Common Tempo Markings

• Largo: 40-60 BPM (very slow)
• Adagio: 66-76 BPM (slow)
• Andante: 76-108 BPM (walking pace)
• Moderato: 108-120 BPM (moderate)
• Allegro: 120-156 BPM (fast)
• Vivace: 156-176 BPM (lively)
• Presto: 168-200 BPM (very fast)
