Study Notes

Analogue to Digital Conversion (A2D)

Computers represent all data, including sound, in binary.
Analogue sound waves must be sampled and stored as binary for computers to understand and process them.
The process of converting analogue sound waves to digital is called Analogue to Digital Conversion (A2D).
A2D involves measuring the amplitude of the sound wave at specific points in time, called samples.
The higher the amplitude of the sound wave, the louder the sound.
Each sample generates a value that is represented in binary and stored.
These samples are used to create a digital representation of the original analogue wave.
The digital wave is stored on secondary storage and can be played back by reversing the A2D process.
The sample rate, bit depth and sample interval can be adjusted to create a digital wave that more closely resembles the original analogue wave.
