You can also use the Web Audio API to directly generate and manipulate audio streams from JavaScript code rather than streaming pre-existing audio files.

This also provides a way to monitor the audio's fetching process so you can watch for errors or detect when enough is available to begin to play or manipulate it.

To allow precise control over your audio content, HTMLMediaElements fire many different events.You can, however, create your own custom controls using JavaScript and the HTMLMediaElement API. If you don't specify the controls attribute, the audio player won't include the browser's default controls.Also available is a guide to the codecs supported for video. We offer a substantive and thorough guide to media file types and the audio codecs that can be used within them. Playback has stopped because of a temporary lack of data The time indicated by the currentTime attribute has been The user agent is trying to fetch media data, but data is unexpectedly Playback is ready to start after having been paused or delayed due to The first frame of the media has finished loading.

See CORS settings attributes for additional information. If invalid, it is handled as if the enumerated keyword anonymous was used. without sending the Origin: HTTP header), preventing its non-tainted use in elements. When not present, the resource is fetched without a CORS request (i.e. If the server does not give credentials to the origin site (through Access-Control-Allow-Credentials: HTTP header), the resource will be tainted and its usage restricted. In other words, it sends the Origin: HTTP header with a cookie, a certificate, or performing HTTP Basic authentication. Sends a cross-origin request with a credential. If the server does not give credentials to the origin site (by not setting the Access-Control-Allow-Origin: HTTP header), the resource will be tainted, and its usage restricted. In other words, it sends the Origin: HTTP header without a cookie, X.509 certificate, or performing HTTP Basic authentication. Sends a cross-origin request without a credential. CORS-enabled resources can be reused in the element without being tainted. This enumerated attribute indicates whether to use CORS to fetch the related audio file. The allowed values are nodownload, nofullscreen and noremoteplayback. The controlslist attribute, when specified, helps the browser select what controls to show for the audio element whenever the browser shows its own set of controls (that is, when the controls attribute is specified). If this attribute is present, the browser will offer controls to allow the user to control audio playback, including volume, seeking, and pause/resume playback.

See our autoplay guide for additional information about how to properly use autoplay. However, this can be useful when creating media elements whose source will be set at a later time, under user control. If you must offer autoplay functionality, you should make it opt-in (requiring a user to specifically enable it). Note: Sites that automatically play audio (or videos with an audio track) can be an unpleasant experience for users, so should be avoided when possible.
