Beat Sample Grid Calculator
Calculate the fractional samples per beat and whole-sample timing error.
Your inputs
Calculation results
Formula & assumptions
Samples per beat = rate × 60/BPM; independently rounded beats may drift.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.

Questions & answers
What does Beat Sample Grid Calculator calculate?
Calculate the fractional samples per beat and whole-sample timing error.
Which units should I enter?
Tempo uses beats per minute. Sample rate uses samples per second. Beats uses beats. Convert values to these units before calculating.
Which formula does it use?
Samples per beat = rate × 60/BPM; independently rounded beats may drift.
What does the included example show?
Tempo: 123 beats per minute; Sample rate: 48000 samples per second; Beats: 16 beats. Result: Samples per beat = 23414.634; Rounded samples per beat = 23415; Rounded whole-span samples = 374634; Repeated rounded-beat error · milliseconds = 0.12195122.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
