Any subsequent attempts will throw an error due to the fact that only one source node can correspond to a media element.Р вЂќР вЂЎeel free to use the code and modify the code as you please. You can only execute this function on any given media element once. This may be useful if you desire to do more with the web audio API regarding this media.Р вЂќР вЂћ reference to the mediaElem passed into the function.Р вЂќР вЂћ function which accepts one parameter indicating a new multiplier (amplification level).Р вЂќР вЂћ function which returns the multiplier (amplification level).

This may be useful if you desire to do more with the web audio API regarding this media. The function will return an object containing all of the following:Р вЂќР вЂћn instance of AudioContext which was used to change the mediaР Р†Р вЂљРІвЂћСћs volume.Р вЂќР вЂћ media source created from the AudioContext instance and the mediaElem. Passing in a number greater than 1 will make the volume be greater than normal and passing in a number less than 1 will make the volume be less than normal. Passing in 1 will simply keep the volume at a normal level. Here is an example pageР Р†Р вЂљРІвЂћСћs code using the function:Р вЂќР’В®ither an tag or a tag for which the volume will be amplified or boosted.Р вЂќР вЂћ number which will basically represent by how much the volume will be multiplied. By simply specifying a reference to the element and a multiplier for the volume we can increase or decrease the maximum volume of audio and video tags.

See the effect on the video and on the underlying events and properties. Play, pause, and seek in the entire video, change the volume, mute, change the playback rate (including going into negative values). The above JavaScript function gives us the ability to amplify (or boost) the volume of a media element well above the normal maximum of 100%. This page demonstrates the new HTML5 video element, its media API, and the media events. Did you know that thanks to the Web Audio API it is possible to boost the volume up PAST 100% on tags & tags? I wrote the following function to do just that:
