Enter the sample rate and buffer size into the calculator to determine the audio latency in milliseconds. This calculator helps in understanding the delay introduced during digital audio processing.

Audio Latency Formula

The following formula is used to calculate the audio latency.

L = (B / S) * 1000


  • L is the audio latency (milliseconds)
  • B is the buffer size (samples)
  • S is the sample rate (Hz)

To calculate the audio latency, divide the buffer size by the sample rate and then multiply the result by 1000 to convert it to milliseconds.

What is Audio Latency?

Audio latency is the delay between when an audio signal is created and when it is heard. It is a critical aspect in digital audio processing, affecting the performance of audio recording and playback systems. High latency can cause noticeable delays that can disrupt the timing of audio events, especially in live performance settings. Understanding and minimizing latency is important for audio engineers and musicians.

How to Calculate Audio Latency?

The following steps outline how to calculate the Audio Latency.

  1. First, determine the sample rate (S) in Hertz (Hz).
  2. Next, determine the buffer size (B) in samples.
  3. Use the formula from above = L = (B / S) * 1000.
  4. Finally, calculate the Audio Latency (L) in milliseconds.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

sample rate (S) = 44100 Hz

buffer size (B) = 512 samples
