static waveform (Read 1458 times)

static waveform
Jul 3rd, 2009, 6:29am  
Hi all,

   i am developing an application where a static waveform of a sound must be visualized. Like the waveforms used on the sound edition tools.
The main issue i have using prototype is that i can visualize the waveform while the audio file is being played, and it cannot be pre-rendered.
I think that i cannot accomplish this task by using Mimic, but i can do it by using ESS.

With the following lines of code i retrieve the samples of a sound file:

AudioChannel ac = new AudioChannel("c:\\r2d201.mp3");
float[] samples = ac.samples;

Now i need to know how can i make the fourier transformation on an entire array of samples, instead of on parts of it using the fft.forward function.

I hope someone can help me because i cannot find a solution right now.

Thanks in advance!

Me too.... see the minim library exemple MouseSaw. it uses a static waveform.... could be a beginning
