The goal of this API is to include capabilities found in modern game audio engines and some of the mixing, processing, and filtering tasks that are found in modern desktop audio production applications. The Web Audio API is a high-level JavaScript API for processing and synthesizing audio in web applications. While audio on the web no longer requires a plugin, the audio tag brings significant limitations for implementing sophisticated games and interactive applications.
Dealing with time: playing sounds with rhythm.It's opensource too: check it out! audica.surge. you must need user interaction to play audio like click on button to play or : I made a lib that lets you make audio visualizations from your audio tag.
