Why sound signals need to be converted before they can be processed by a computer.?

Sound signals are analog in nature, consisting of continuous waveforms that represent variations in air pressure. Computers, however, operate using digital data, which is represented in discrete binary values (0s and 1s). To process sound signals, they must be converted from their analog form into a digital format through a process called analog-to-digital conversion (ADC), allowing computers to analyze, store, and manipulate the audio data effectively.
