I don't have CS3 yet, but what is that ? :
Sound.computeSpectrum()
This method analyzes all the sound that played and returns a
ByteArray containing 512 normalized values (-1 to 1) that you can use
to visually display the sound waveform (256 values for the left
channel and 256 values for the right channel). You can use these
values to create Audio Equalizers for Media Players as well as visual
experiments that react to the sound that played.

So i got my AS3 books finally. Essential AS3 by Moock, AS3
animation/making things move and AS3 design patterns. Of these 3,
none give particular interest in the sound API. Making things move
takes a fleeting glance at AS3 sound, limited to a = new Sound();
a.play();, and Design Patterns makes an equally simple example.
The AS3 docs (F1 in the IDE) suggests a hack of a class to
encapsulate Sound handling and otherwise assures us that the AS3
api is "powerful".
I still fail to see why.
When Andre Michelle makes an AS3 303 emulator we're all impressed,
but we somehow fail to realize he made it with *hacks*. Advanced
AS3 sound manipulation is effectively barred to those not of his
calibre. For "the rest of us", we're stuck waiting for someone to
build a robust sound control API wrapper for AS3's frankensteinian
mess. In my opinion, AS3 sound is only as strong as you're willing
to take punishment. Things were rough in AS2, but we could work it.
In AS3 it's equally rough, with added edges.
Considering the *vast* improvements AS3 and the new VM gave us, i
find it bewildering how something so core to the multimedia
experience has been either ignored completely or thrown in as an
afterthought. I'm told by peers that "oh you know, Sound is weak in
Flash". Like a dogma. Which makes me think engineers threw a
roundtable to somehow assure that in their shiny new VM, Sound
remained weak.
I have never seen an AS topic so skirted. It's like a dark secret
nobody really wants to discuss. Like pooping.
Either people out there *don't care about sound* which blows my
mind, or Adobe didn't give a shit. I'm trying to port my AS2 3d
sound positioning and effects control library to AS3 and, right
now, it's disillusioning and sometimes infuriating.
Dual stop methods for streaming and preloaded audio, the
contextually "wrong" of which doesn't generate exceptions, but
sound glitches.
Soundchannels allow for quick and easy orphaning of sound. Go orphans!
Soundmixer only really stopping sound and giving an *incomplete*
spectrum, ignoring Microphone.
There's parts of AS3 that force us to get stricter, and this is
fine. The sound library forces us to either wrap or get sloppy.
So am i right about this? Do Flash developers really care this
little about audio?
Positive sides? Loading sound resources externally and
SoundTransform. And still being able to actually play audio.
I don't know of a fix for this beyond doing the sound API over with
a little more consideration. But i'd love to hear some best
practises and experiences from other developers. Anything to learn
more about this POWERFUL NEW API. Yeah.
