A sound signal is a representation of sound waves that can be analyzed or transmitted. It can be in the form of an electrical signal, which is generated by converting sound waves into an electrical format. This conversion allows sound to be processed, recorded, or transmitted over distances, such as in telecommunications or audio recording. Sound signals can be categorized into analog and digital types. Analog signals are continuous and represent sound in a wave-like form, while digital signals are discrete and represent sound as binary data. Both types are essential in various applications, including music production, broadcasting, and communication systems.
