p5.js | setVolume() Function

The setVolume() function is an inbuilt function in p5.js library. This function is used to control the volume of the played audio on the web. This function has a range of between (0.0) which means total silence to (1.0) which means full volume. This volume also can be controllable by a slider var by dividing that in different ranges.

Syntax:
