Audio delay calculator

Give the tempo and the time signature

Express the length of the delay as fractions of the beat

Beats/minute → msecs/beat

• Beats-per-minute: `60` BPM
• Beats-per-second: `1` Hz
• Length of 1 beat: `1` second = 1000 msec
• Length of 1 bar (4 beats): `4` second
• Fraction → msecs

• Delay = 6 / 8 of a beat
• = `750` msecs
• Repeated delays

• delay syncs with the beat after 4 repetitions = 3 beats
• x 2 = 1500 msecs
• x 3 = 2250 msecs
• x 4 = 3000 msecs
• Delay vs beat
