Audio Latency Calculator

How it Works

Latency (ms) = (Buffer Size / Sample Rate) * 1000.

What is Audio Latency Calculator?

Determines the time delay introduced by digital audio buffering.

Step-by-Step Guide

  1. Buffer: Samples (e.g. 256).
  2. Rate: Sample Rate (e.g. 44.1kHz).
  3. Result: Delay in ms.

Example

Input: 256 samples, 44.1kHz

Result: 5.8 ms

FAQ

What is acceptable?

<10ms for vocals/guitar; <20ms for keys.

Round trip?

Multiply result by 2 (roughly).

Buffer size?

Lower = less lag, higher CPU usage.

Sample rate effect?

Higher rate = lower latency.

Hardware?

Interface drivers add extra hidden latency.

Conclusion

Low latency (<10ms) is crucial for real-time monitoring. Increasing sample rate lowers latency but increases CPU load. Round-trip latency includes input + output + converter delay.
