how do i use mirfeatures in matlab

MIRToolbox is a collection of functions that allow users to extract features from audio signals in Matlab. Mirfeatures function is one of the functions in the toolbox, which is used for feature extraction.

First, you need to download and install the MIRToolbox by following the instructions in the installation guide. After that, make sure you have added the toolbox folder to your Matlab path using addpath() command.

To use the mirfeatures function in Matlab, you need to specify the audio file that you want to extract features from. Here is an example code snippet:

main.m
% Load an audio file
[x,fs] = audioread('audio_file.wav');

% Extract features using mirfeatures function
features = mirfeatures(x,fs);

The output of mirfeatures function is a struct array containing various features extracted from the audio signal. You can access the features using dot notation, for example:

main.m
% Access spectral flux feature
spectral_flux = get(features,'Spectral Flux');
