Audio Buffer Latency Calculator
Estimate ideal buffering delay from buffer size, rate and buffer count.
Your inputs
Calculation results
Formula & assumptions
Latency = frames per buffer × buffer count/sample rate; hardware and processing delay are additional.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Audio Buffer Latency Calculator
Estimate ideal buffering delay from buffer size, rate and buffer count.
- Enter frames per buffer, sample rate, queued buffers using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Frames per buffer: 256 frames Sample rate: 48000 samples per second Queued buffers: 2 buffers One buffer · milliseconds: 5.3333333 Queued buffer delay · milliseconds: 10.666667
Questions & answers
What does Audio Buffer Latency Calculator calculate?
Estimate ideal buffering delay from buffer size, rate and buffer count.
Which units should I enter?
Frames per buffer uses frames. Sample rate uses samples per second. Queued buffers uses buffers. Convert values to these units before calculating.
Which formula does it use?
Latency = frames per buffer × buffer count/sample rate; hardware and processing delay are additional.
What does the included example show?
Frames per buffer: 256 frames; Sample rate: 48000 samples per second; Queued buffers: 2 buffers. Result: One buffer · milliseconds = 5.3333333; Queued buffer delay · milliseconds = 10.666667.
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.
