NAudio fft result gives intensity at all C # frequencies I have a working implementation of NAudio Wasapi audio recording and FFT data. Most of the data that I get is the same as it should be, but every time in the interval (from 10 seconds to minutes) it shows the amplitude at …

Finally, the FFT results contain a mirrored image. Only the first half is of use, the second contains the same data in reverse. Throwing that away brings a usable spectral diagram of the recorded audio.

I'm using NAudio.DSP library for FFT calculations and using Hamming window with length of FFT. Here is the code: ... I believe the signal should get more detailed but the result is like I'm using full FFT result not the first half (real) part $\endgroup$ – hessamj. Aug 25 '14 at 9:00
Fast Fourier Transformation FFT - Basics - NTi Audio

This is always an integer power to the base 2 in the FFT (e.g., 2^10 = 1024 samples) From the two basic parameters fs and BL, further parameters of the measurement can be determined. Bandwidth fn (= Nyquist frequency). This value indicates the theoretical maximum frequency that can be determined by the FFT. fn = fs / 2

I want to get frequency and amplitude from wave file using c#. I tried naudio and FFT, but result is nothing. can you help me please. NAudio.Wave.WaveChannel32 wave = new NAudio.Wave.WaveChannel32(new NAudio.Wave.WaveFileReader(open.FileName)); byte[] buffer = new byte[16384]; int read = 0; double[] _fft; while (wave.Position < wave.Length) { read = …

Download demo project - 33.3 KB; Introduction. The Fast Fourier Transform (FFT) allows users to view the spectrum content of an audio signal. The FFT code presented here was written by Don Cross, his homepage appears to have subsequently been taken down.Rather than explain the mathematical theory of the FFT, I will attempt to explain its usefulness as it relates …
