Detailed explanation-1: -Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44, 100 times per second, each with 16-bit sample depth.

Detailed explanation-2: -In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.

Detailed explanation-3: -To do this, sound is captured-usually by a microphone-and then converted into a digital signal. An analogue-to-digital converter will capture a sound wave at regular time intervals. This recording is known as a sample . This data is then stored in a file for later use.

Detailed explanation-4: -Sampling is a method of converting an analogue audio signal into a digital signal. While sampling a sound wave, the computer takes measurements of this sound wave at a regular interval called sampling interval. Each measurement is then saved as a number in binary format.
