Hey guys this is my third post on SPECTRUM ANALYZER.

I want to know haw to get amplitude(in numbers) of different frequencies of an audio signal from my sound card so that I can display it graphically. I visited many sites of FFT but di'n get any such tutorial or cade specially for audio spectrum analyzer.

Perhaps no-one knows

Noone's not that good at this kind of stuff.

Hey guys

I got it! Now I know how to make a cool spectrum analyzer like JET AUDIO. It's extremely simple. Just get the soundcard volume and transform it into FOURIER series.

I didn't knew it was that simple that. I was dieing hard since last one month to make it and today when I opened my last semesters book, the FOURIER series formula was right in it. I just entered it in my prog. and
Hurray..............Wheeee......Peeeeeeee

Now just the calibration is remaining.
Does anyone know any program which generates sound of audio range frequencies(20Hz to 20,000Hz). I downloaded one such program five months back but since it was a trialware I deleted it after expiring. I also forgot the URL.

Can anyone help me.


Thanks
