👉 A waveform is a mathematical representation of an audio signal or any other type of signal that contains time and frequency information. It can be defined as any function that maps from time to amplitude values, typically in the form of sine waves, square waves, exponential functions, etc. In more technical terms, a waveform can be thought of as representing the time-varying properties of an audio or other signal, such as its spectral content, frequency components, and phase. It is used in various
