Setting waveViewer1 to a array of float values

Nov 16, 2013 at 9:55 PM
I do a FFT to my input signal
but now I am to display it with waveViewer1

but I think I have to make a WaveFormat out of the array 1st?
is this so?
how would I do this?

Dear Sir,

I need to get FFT of my mp3 file. I need to get the amplitude at a ceratain frequency. Can you please supply me with your code about how to implement FFT.
Thanks for support.

do you know display raw float data in to a waveViewer1?

waveViewer displays waveforms, not FFTs. It's a very simple control, and will probably be removed from NAudio. For visualizations of FFTs, have a look at the demo in the WPF Demo source code. Also, if you are a Pluralsight subscriber I explain in detail how audio can be visualised in Module 7 of this course:

Dear btb4198 ,

I need to make FFT for my mp3 file. Can you please write down the code you made for FFT . FFT is a very complex issue for me.
Thanks for support.

I am still working on my DSP class...
during testing it work some times but not all the time

Dear btb4198

I am now trying to detect dtmf tone from wav file. I need to get the frequency. of a small wave file. just to get the 2 main peaks frequencies.
does your dsp class convert wav file, or mp3 file to frequancy array through fft.

Sorry , but i am really lost into FFT :(

Thanks for support

does you still need an FFT?
I got minez to work a while ago..

let me know if you need one
