99 BPM in Milliseconds: Delay Times and Note Lengths
At 99 BPM one beat (a quarter note) lasts 606.061 ms and one bar of 4/4 lasts 2.424 seconds. Below are the delay times for every note value, the same notes in Hz, bar and phrase lengths, samples per beat and the genres that typically sit at this tempo.
99 BPM at a glance
- One beat at 99 BPM lasts about 606.06 ms (60,000 divided by 99), an eighth note about 303.03 ms and a dotted eighth about 454.55 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 100 BPM, with 600 ms per beat.
- A beat is 26,727.273 samples at 44.1 kHz and 29,090.909 samples at 48 kHz, neither a whole number, so sample accurate loop points round slightly at both rates.
- A 4 bar phrase in 4/4 takes about 9.697 seconds, and 3 minutes of music at this tempo holds 74.25 bars of 4/4.
- Going from 99 to 100 BPM shortens each beat by 6.061 ms, about 1% of the beat.
- An LFO synced to quarter notes runs at 1.65 Hz; synced to whole bars of 4/4 it runs at 0.4125 Hz.
