The adoption of HTML audio, as with HTML video, has become polarized between proponents of free and patent-encumbered formats. In 2007, the recommendation to use Vorbis was retracted from the HTML5 specification by the W3C together with that to use Ogg Theora, citing the lack of a format accepted by all the major browser vendors.
GLICOL, a graph-oriented live coding language written in Rust Hierarchical Music Specification Language (HMSL), optimized more for music than synthesis, developed in the 1980s in Forth Impromptu , a Scheme language environment for Mac OS X capable of sound and video synthesis, algorithmic composition, and 2D and 3D graphics programming

The HTML5 draft specification adds video and audio elements for embedding video and audio in HTML documents.The specification had formerly recommended support for playback of Theora video and Vorbis audio encapsulated in Ogg containers to provide for easier distribution of audio and video over the internet by using open standards, but the recommendation was soon after dropped.
Unified Speech and Audio Coding (USAC) is an audio compression format and codec for both music and speech or any mix of speech and audio using very low bit rates between 12 and 64 kbit/s. [1] It was developed by Moving Picture Experts Group (MPEG) and was published as an international standard ISO / IEC 23003-3 (a.k.a. MPEG-D Part 3) [ 2 ] and ...
The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997. [3] A form of HTML, known as HTML5, is used to display video and audio, primarily using the < canvas > element, together with JavaScript.
Notation represents the number of channels, not the number of speakers. The first digit in "5.1" is the number of full-range channels. The ".1" reflects the limited frequency range of the LFE channel. For example, two stereo speakers with no LFE channel = 2.0 5 full-range channels + 1 LFE channel = 5.1
The clock rate of the PC's programmable interval timer which drives the speaker is fixed at 1,193,180 Hz, [3] and the product of the audio sample rate times the maximum DAC value must equal this. Typically, a 6-bit DAC [ 8 ] with a maximum value of 63 is used at a sample rate of 18,939.4 Hz, producing poor but recognizable audio.
