Acoustic Tracker (Updated) This demo uses sound to identify the location of an object. The listening array is two microphones, which will allow us to estimate the position along the straight line between the microphones. Location estimation is based solely on the rms value of the noise measured at the two microphones. Note...

DFT on a specified frequency Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set...

HOSA - Higher Order Spectral Analysis Toolbox There is much more information in a stochastic non-Gaussian or deterministic signal than is conveyed by its autocorrelation and powerspectrum. Higher-order spectra which are defined in terms of the higher-order moments or cumulants of a signal, contain this additional information. The...
