1

Sound file size formula

File size = sample rate × duration (s) × bit depth

2

Sample rate

The number of samples taken per second, measured in Hz (e.g., 44,100 Hz).

3

Duration (s)

The length of the audio recording in seconds.

4

Bit depth

The number of bits used to store each sample, affecting sound quality and file size.

5

Analogue to digital conversion

The process of converting continuous analogue signals into discrete digital data.

6

Sampling

Measuring the amplitude of an analogue signal at regular intervals.

7

Sample rate

The frequency at which samples are taken, measured in Hz.

8

Bit depth in ADC

The number of bits used to represent each sample, determining the precision of the digital representation.
