Feature Extraction. Mel spectrogram, MFCC, pitch, spectral descriptors. Extract features from audio signals for use as input to machine learning or deep learning systems. Use individual functions, such as melSpectrogram, mfcc, pitch, and spectralCentroid, or use the audioFeatureExtractor object to create a feature extraction pipeline that minimizes redundant …
matlab - Audio Feature Extraction using FFT, PSD and …
https://stackoverflow.com/questions/14429885/audio-feature-extraction-using-fft-psd-and-stft-and-finding-the-most-powerful-f
For exmaple, [B,IX] = sort (p.data) and freq_maxn = p.Frequencies (IX (1:n)) 4) PSD = |FFT|^2/N. In other words, PSD is simply a scaled version of the squared magnitude of the FFT. However, for real valued signals only half the FFT is used since the other half is …

I go through this code MFCC feature extraction for MFCC feature extraction for speech signal. How we can implement it for multiple audio signals and get the feature vectors and for implementing LPCC to get its features vectors.*
A Matlab Toolbox for Musical Feature Extraction from Audio
https://dafx.labri.fr/main/papers/p237.pdf
MIRToolbox is a Matlab toolbox dedicated to the extraction of musically-related features from audio recordings. It has been de-signed in particular with the objective of enabling the computation of a large range of features from databases of audio files, that can be applied to statistical analyses. Few softwares have been proposed in this area.
