Audio can be of two different types, analogue and digital. When you speak or sing, the sounds you you make, or those that you can hear, are in analogue or wave format. However, computers are digital devices, so we need to convert audio from analogue to digital format before using it on a computer.
Digital audio technology lets you record, edit, and play digital audio files on a computer. It also allows you to communicate with the computer using speech.
