Audio - converting analogue to digital sound

Question 1

converting analogue to digital sound

Answer 1

Analogue sound can be converted into digital sound through the use of a analogue digital converter

Question 2

how is sound captured

Answer 2

Sound is captured at regular intervals as samples through an input device, e,g microphone which creates electronic signals based on the sound’s volume and pitch.

o The electronic signals are sent to and ADC, e.g. sound card, and assigned a binary digit which represents the volume and pitch of the sound captured.

o Through the ADC, the sound is converted from analogue sound into digital audio as binary. The quality of the conversion is determined by the sample size and rate.
