Calculating the size of digital audio The formula is as follows: rate × duration × resolution × number of channels 8 The answer will be in bytes Where: sampling rate is in Hz Duration/time is in seconds resolution is in bits (1 for 8 bits, 2 for 16 bits) number of channels = 1 for mono, 2 for stereo, etc. 19. 20.

The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.

Nyquist Rate. The Nyquist rate is a concept derived from digital sampling theory which states that to accurately represent a particular frequency, the signal must be sampled at twice the rate of that frequency. For example, to create an accurate digital representation of 10 kHz, you would need to use a minimum 20 kHz sampling rate.

For audio, typical sampling rates are from 8 kHz (8,000 samples per second) to 48 kHz. This range is determined by Nyquist theorem discussed later.
