Call extract to extract the audio features from the audio signal. features = extract (aFE,audioIn); Use info to determine which column of the feature extraction matrix corresponds to the requested pitch extraction. idx = info (aFE)
Feature Extraction - MATLAB & Simulink
https://www.mathworks.com/help/audio/feature-extraction.html
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 calculations.
Streamline audio feature extraction in the Live Editor ...
https://www.mathworks.com/help/audio/ref/extractaudiofeatures.html
The Extract Audio Features task enables you to configure an optimized feature extraction pipeline by selecting features and parameters graphically. You can reuse the output from Extract Audio Features to apply feature extraction to entire data sets. The task automatically generates MATLAB ® code for your live script. Using this task, you can:
Streamline audio feature extraction - MATLAB - …
https://la.mathworks.com/help/audio/ref/audiofeatureextractor.html
MATLAB® automatically optimizes the queued calculations by minimizing the number of passes through the data. If you have Parallel Computing Toolbox™, you can spread the calculations across multiple machines. The audio data is represented as an M-by-1 tall cell array, where M is the number of files in the audio datastore.
Extract cepstral features from audio segment - MATLAB
https://www.mathworks.com/help/audio/ref/cepstralfeatureextractor-system-object.html
Frequency-Domain Voice Activity Detection and Cepstral Feature Extraction Many feature extraction techniques operate on the frequency domain. Converting an audio signal to the frequency domain only once is efficient. In this example, you convert a streaming audio signal to the frequency domain and feed that signal into a voice activity detector.
A Matlab Toolbox for Musical Feature Extraction from Audio
https://dafx.labri.fr/main/papers/p237.pdf
MOTIVATION AND APPROACH 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.
