Audio Analyser with VB

[sangoku]

Hi all,
I try to make an audio analyser with VB like winamp's plugins.
Can someone help me.:rolleyes:
I want to syncronized event with audio.
Thanks

As I said to you on Mirc, the only plugins you can make with VB are general plugins coz' it's too slow to make vis...Look for the VB wrappers somewhere on the site

the wrapper: http://www.winamp.com/nsdn/vault/
powerbasic vis plugin code: http://www.fullspectrum.com/deeth/programming/mp3dev.html

dunno if the powerbasic stuff can help you

ok thanks all :)
But all what you say use winamp :weird:
I search a way to make like an spectrum audio analyser without winamp.
A way to analyse the frequence and the beat an audio signal.

Well, you would simply need to take the Fast-Fourier Transform of the audio and plot it (if you want to make a spectrum analyzer). For an oscilliscope, just plot the waveform data. The harder part would be to synchronize the audio with the visualization. For a really good implementation of the FFT that you can use from VB, check out the Intel Signal Processing Library at http://developer.intel.com/software/products/perflib/spl/index.htm . This comes with a C (or maybe C++) spectrum analyzer sample that might help you.
