What does 'audio effects' refer to in music processing?

'Audio effects' in music processing refers to modifications applied to sound to change its character. This can include a variety of techniques, such as reverb, delay, distortion, compression, and equalization, each of which alters the audio signal in a specific way to enhance or transform the listening experience. By applying these effects, producers and musicians can create unique soundscapes, add depth to tracks, or emphasize particular aspects of the music, such as vocals or instruments.

In contrast, visual representations of sound waves would not be considered an audio effect; they serve to illustrate the characteristics of sound rather than modify it. The interaction of multiple musicians relates more to performance dynamics rather than to processing audio through effects. Lastly, recordings of live performances are the end product of music creation and do not pertain to the modification of sound itself, which is central to the concept of audio effects.
