I have noted an asymmetry between canvas and audio:
canvas supports loading of ready-made images _and_ pixel manipulation
(get/putImageData).
audio supports loading of ready-made audio but _not_ sample manipulation.
With browser JavaScript getting faster all the time (Squirrelfish...),
My understanding of HTMLMediaElement is that the currentTime, volume
and playbackRate properties can be modified live.
So in a way Audio is already like Canvas : the developer modify things
on the go. There is no automated animations/transitions like in SVG
for instance.
Doing a cross
Thanks for all the feedback sofar!

As others have pointed out, I think you're asking for a new element,
where you can 'draw' audio as well as pre-load it, just like canvas
where you can load pictures and also draw them. This is not the audio
element, any more than canvas
canvas?

For the sketched use case - in-browser audio editor -, functions on
sample regions from {cut/add silence/amplify/fade} would be nice and

I think an interesting approach for an audio canvas would be to allow
you to both manipulate audio data directly (through a
getSampleData/putSampleData type interface), but also build up an audio
filter graph, both with some predefined filters/generators and with the
ability to do filters in

I believe your use case of creating an adio editor through using the

that kind of functionality.
Your belief is fine with me - you haven't seen the prototype running on
Safari ;-)

Having removed everything else in these sections, I figured there wasn't
that much value in requiring PCM-in-Wave support.

It would work fine for sound effects...

Hi,
please note that with cue ranges removed, the last HTML 5 method to
perform audio subinterval selection is gone.
AFAIK, when dropping support for 'start' and 'end' attributes it was
noted on this list that cue ranges would provide a replacement to
dynamically select, say, a 3-second range
Hi,
The .start/.end properties were dropped in favor of media fragments,
which the Media Fragments Working Group is producing a spec for.
Who decided this? Has this decision been made public on this list?

Not quite. You can always use the video.currentTime property in a
javascript to directly jump to a time offset in a video
