Work out audio sample size instantly with clear inputs, formula shown and shareable results.
Uncompressed audio uses sample rate times bit depth over eight times channels bytes per second, and the Nyquist limit puts the highest reproducible frequency at half the sample rate. The Nyquist limit is why 44.1 kHz was chosen for CD: it covers the 20 kHz limit of human hearing with a little margin for filtering.
Data rate
bytes per second = sample rate x bit depth / 8 x channels
Nyquist frequency
highest frequency = sample rate / 2
bytes per second = sample rate x bit depth / 8 x channels. Uncompressed audio uses sample rate times bit depth over eight times channels bytes per second, and the Nyquist limit puts the highest reproducible frequency at half the sample rate.

Enter sample rate, bit depth, channels, duration. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
