THE NUMBERS, EXPLAINED

How to use this calculator.

Sample count is per channel; adding channels does not increase duration.

Start with your inputs

Enter samples per channel, sample rate (hz). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.

InputExample value
Samples per channel48000
Sample rate (Hz)48000

A worked example

With the example inputs above, duration (seconds) is 1. Change the inputs to explore your own scenario.

Putting the example numbers into the formula

Duration (seconds)
(48000) ÷ (48000) = 1

All results for the example inputs above
ResultExample answer
Duration (seconds)1

Assumptions and limits

Sample count is per channel; adding channels does not increase duration.

Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.

Questions about this tool

What does the result tell me?

Duration (seconds). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.

Why might another calculator differ?
