Digital Audio

How is sound digitally recorded? And how important are sample rates and resolutions to the process? Ian Waugh looks at the crystal-clear world of digital audio.

Digitising audio is the process of converting sound into a series of numbers. The hardware that does the job is known, naturally enough, as an audio-to-digital converter, usually abbreviated to ADC. A digital-to-audio converter (DAC) reverses the process, converting digital audio in a sampler or on a hard drive, for example, to sound that we can hear.
