Sample rate: 44100 samples per second Duration: 2.5 seconds Samples per channel: 110250 Actual duration · seconds: 2.5 One sample · microseconds: 22.675737
Questions & answers
What does Audio Sample Count Calculator calculate?
Translate a duration to sample count and sample-period precision.
Which units should I enter?
Sample rate uses samples per second. Duration uses seconds. Convert values to these units before calculating.
Which formula does it use?
Sample count = round(rate × seconds).
What does the included example show?
Sample rate: 44100 samples per second; Duration: 2.5 seconds. Result: Samples per channel = 110250; Actual duration · seconds = 2.5; One sample · microseconds = 22.675737.
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.
