Audio Sample Count Calculator
Enter a duration, sample rate, and channel count to calculate the total number of samples.
Samples per channel
7,938,000
Total data points
15,876,000
Samples per channel = duration × sample rate; total data points multiplies that by the channel count — useful for estimating buffer sizes or array lengths when writing audio-processing code.
How to use this tool
- 1Enter the duration in seconds.
- 2Enter the sample rate in Hz.
- 3Enter the number of channels.
- 4See the samples per channel and total data points.
Frequently asked questions
Why does channel count matter for the total?+
Each channel stores its own independent set of samples, so a stereo file has twice as many total data points as a mono file of the same duration and sample rate.
