I've cracked Flash open again for some simulations and I am looking for
some code that will allow me to provide a visualizer per audio file as it
plays. computeSpectrum is out obviously.
Anyone have any code that can provide super-simple (say scaling a clip)
based on extracted values while the aud
Hi Ben,
There is a nice example of what you touched on with your question
that helps a bit explaining how with sound time & frequency "domains"
are related.

FFT's and DFT's are fairly nasty beasts t
Ben,
Your going to want to perform an FFT (Fast Fourier Transform) and move from
the time domain to the frequency domain.
And to be more specific I believe you are gonna want to perform a Discrete
Fourier Transform.
I know a lot of work has been done on this in C and perhaps you could find
somet
Hi
1) From the docs:
http://help.adobe.com/en_US/AS3LCR/Flash_10.0/flash/media/Sound.html#extract()
The audio data is always exposed as 44100 Hz Stereo. The sample type is a
32-bit floating-point value, which can be converted to a Number using
ByteArray.readFloat().
So, each sample is 32 bits, t
Hey guys,
I'm just digging into the Sound.extract feature in FP10. I've been
using code found at http://www.bytearray.org/?p=329 to learn from, but
have a few questions. I'm able to create a waveform and draw to the
stage, but want to take it beyond that.
Basically the code I have is this:
