How to use this calculator
- Enter sample rate in Hz.
- Enter duration in s.
- Enter channels in count.
- Enter bits per sample in bits.
- Select Calculate and keep the output unit with the answer.
Before you use the answer
Write down whether a size uses decimal or binary prefixes and whether a rate counts bits or bytes. Compare the same system boundary on both sides of a performance calculation. Measured throughput is usually a more useful planning input than the maximum number on a product label.
Container overhead and compressed formats do not follow this raw-buffer calculation.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
