Samples per Beat

General

• the Duration of 1 Beat is 60/BPM Seconds

• the Number of Samples per Second is Defined by the Sample Rate (SR)

• so the Math to Calculate the Number of Samples per Beat is 60/BPM x SR

Example 1

• Tempo is 120 BPM and SR is 44100

1) Since 1 Beat is 60, we need to Divide 60 / 120 

• 60 / 120 = 0.5

2) Since SR is 44100 we Need to Multiply that 0.5 by 44100

– 44100 x 0.5 = 22050 Samples per Beat

Example 2

• Tempo is 103 BPM and SR is 44100

1) Since 1 Beat is 60, we need to Divide 60 / 103 

• 60 / 103 = 0.5825242718

2) Since SR is 44100 we Need to Multiply that 00.5825242718 by 44100

• 44100 x 0.5825242718 = 25689.3203883495 Samples per Beat
