The term "audio controls" refers to a set of buttons or switches on an electronic device that allow users to control and adjust various aspects of the audio output. These controls typically include options for volume, balance (left/right), tone (treble/bass), and sometimes even specific presets for different listening modes such as music, speech, or surround sound. The purpose of these controls is to provide users with flexibility in customizing their listening experience according to their preferences and the type of content they are consuming.
