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
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 to
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
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,
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:
