Does anyone know how to plot actual time interval in Spectrogram using STFT? I want to analyze an event in a signal in a certain time span, but using the spectrogram built in function plots in Spectrogram from 0, while I want it to be plotted from for exp. 5083s time span as seen ...
here data are supposed to come from a wav file but you can easily adapt the code to your own needs
In MATLAB Online öffnen If you output the vector of frequencies from spectrogram(), you will have the frequency information. ThemeCopy t=0:0.001:2; x=chirp(t,0,1,150); [y,f,t,p] = spectrogram(x,256,250,256,1000); Each row of p corresponds to the frequency at the correspon...
Can somebody help me to clarify my doubt ? can Mel-spectrogram be used for feature extraction. If Yes the how ? S = melSpectrogram(audioIn,fs) it is the inbuilt function in matlab, in this S represent what? How do i extract feature vector using the above command? Tha...
In previous releases, cumsec function with no output arguments launched the Filter Visualization Tool to plot the magnitude response of the cumulative sections. You do not need to make any changes to your code. However, to plot the magnitude response of the cumulative sections, use the fvtool ...
