Sound Sampling: Sample Rate and Bit Depth

Analogue wave (continuous) Quantised digital sample

Y-axis shows the bit depth codes for the current bit depth (e.g. 4 bits shows 0000 to 1111).

Student name

Sample rate (samples per second)

6 Hz

Bit depth (bits per sample)

4 bits

Duration (seconds)

3 s

Sound file size = (samples per second) × (bits per sample) × (length in seconds)

Term	Your value
Sample rate (samples per second)
