Hi,
computeSpectrum will only do small chunks at a time - it might not
give you the "spectrum" from the whole wave form.
If you are trying to do Voice Recognition, you will need some
serious computing power and ActionScript may, or may not be too slow to
handle this. It certainly won't work in realtime so don't expect
miracles with the AVM.
Speech recognition may use FFT's to help match up parts of the sound
to pre-recorded samples, but that's as far as my knowledge goes.
Your best bet is to look at places like http://www.voxforge.org/ and
google for speech recognition, etc.
Depending on your RIA, you could always find a way of cheating
possibly... ...e.g. find a speech-to-text engine and write a small
application that "pipes" the output into Flash, etc.

Hi Allandt, Thanks for the article link. I read through and pls correct me
if I'm wrong: You can take a snapshot of an audio file with the
computeSpectrum() method and place that data in a ByteArray object, is this
right? So, now my question is, can you take snapshots of two audio files and
compare their ByteArray objects, and then perform an action based on the
comparison? Like, the ByteArray objects match up 90% then trigger this
event.
Muchos gracias, juju

Where are the Actionscript Sages when you need them :(

Thanks Latcho, can you please describe the process a little bit. What
actually is going on? How is the FFT used to compare the wav files? Is it
comparing header data or something? And what about MP3 files, can they be
used instead of wav? Thanks, juju
P.S. Has to be AS3, trying to make a Flash RIA.

I'd suggest you first get down in audio math and algorithms and indeed
FFT.
If you're done with that... choose whatever language you like and
preferably a faster one then AS3.
But it is not impossible to answer your question.

Hi All, how do you compare two audio files with actionscript? I heard
something about Fast Fourier Transform, but don't understand how it
works. What I'm trying to do is a basic voice recognition programme,
similar to the one on symbian mobile phones where you can give word
commands to your phone. Can this be done in actionscript?
Thanks and cheers, juju
