Understanding Sound Types
Analogue Sound Explained
Analogue sound imitates the vibrations of real sound. Its electrical signal has an analogue curve similar to a real sound wave.
Digital Sound Explained
Digital sound recording does not imitate vibrations but converts them into a binary code, the language computers use.
Digital sound is obtained through a converter. It transforms real sound (analogue) into a computer-readable format.
The Digitization Process
Role of the Converter
A converter is a device that transforms real sound into digital sound. The process is called sampling.
Sound Reproduction
To reproduce sound, the converter follows the inverse process, transforming the digital information back into real sound.
