![]() ![]() You can experiment with the small demo that I’ve created on CodePen, or just have an overview of the possibilities by having a look at the code below. There are another thing I have to tell you is that the volume range of an HTML5 video/audio player has the volume range between 0 and 1. The CSS properties that can be used are: width, box-shadow, border-radius and transform. ![]() Īs of 2019, CSS styling options for the HTML audio tag are quite limited. Basic audio operations are performed with audio nodes, which are linked together to form an audio routing graph. The following example shows how you can build a rudimentary audio player with basic controls (Play, Pause, Volume Up, Volume Down) using HTML and JavaScript. The Web Audio API handles audio operations inside an audio context, and has been designed to allow modular routing. Ĭontroling a HTML audio player with JavaScript is pretty easy. It accept 3 values: none (If you don’t want the file to be buffered), auto (If you want the browser to buffer the file, and metadata (To buffer only metadata when page loads). To do so, you can use the preload attribute. When playing large files, it is a good idea to buffer those files in order to provide visitors a smooth listening experience. If the visitor’s browser doesn’t support HTML audio, a message will be displayed instead of the audio player. It is however possible to notify people who are using outdated browsers that the tag isn’t supported.Īs shown below, you can simply embed any message of your choice within the tag. It can be done easily, using the type attribute on the source element. Any subsequent attempts will throw an error due to the fact that only one source node can correspond to a media element.įeel free to use the code and modify the code as you please.When using different file formats, it is a good practice to specify the MIME type of each file in order to help the browser localize the file it supports. 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.Ī reference to the mediaElem passed into the function.Ī function which accepts one parameter indicating a new multiplier (amplification level).Ī function which returns the multiplier (amplification level). NOTE: Only one source node can be created from an element.Ī media gain created from the AudioContext instance and the mediaElem. 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:Īn instance of AudioContext which was used to change the media’s volume.Ī 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 page’s code using the function:Įither an tag or a tag for which the volume will be amplified or boosted.Ī 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. 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%. 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: To set a particular level of volume at the start, you can simply use JavaScript and set the volume of the audio sound. ![]()
