Breakthroughs In HTML Audio Via Manipulation With JavaScript

jamienk writes "Imagine if you could grab and manipulate audio with JavaScript just like you can images with Canvas. Firefox experimental builds let you do just that: crazy audio visualizations, a graphic equalizer, even text-to-speech, all in JavaScript! Work in progress; you need a special build of Firefox (videos available), being worked on via W3C."

    You mean that you expect this to actually be used?

    IE doesn't even have support for canvas, Firefox has had it from 3.0 at least, and I think even 2.0 had some support.

    If IE still has more than 30% worldwide marketshare, and doesn't have basic requirements for this, its not going to be used. Period.

    Canvas has been around for ages and is there even a single practical example on a site people use daily? Yeah, there are about a million tech demos but very little actual use because IE doesn't support it.

    Third, unlike Theora and H.264, Vorbis is actually much better than MP3.

    Vorbis has smaller file sizes for the same quality or better quality for the same file size (q1 (~80kbps) is easily comparable to 128kbps MP3).
    Vorbis also supports up to 255 channels with official channel ordering specs up to 8 channels (7.1), while MP3 only supports mono and stereo.
