sinus wave of fft

Jun 18, 2011 at 11:26 PM

does anyone know how to create a sinus wave out of the fft data?

I cant find anything >.<

I'm not sure what you mean. Do you want to do an inverse FFT?

something like that

How to calculate that what name does it has? Do you now any websites or something else that describs how to calc something like that.

And how to draw that very efficient

that's not drawn from the FFT, it's just the waveform. NAudio does have some waveform drawing code, but it is not super efficient.

oh really wheres the difference?

And another question what would be an efficient code. It should not look like it is lagging. So i may would have to return an image like bass.dll does?
