read multiple audio files as an index, and get length of each file in matlab

main.m
% specify path to the directory containing audio files
path = './audio_files/';

% get list of audio files in the directory
dir_info = dir([path '*.wav']);
% alternatively, you can use different extension such as .mp3, .flac, etc.

% loop through each file and read it
for i = 1:numel(dir_info)
    % read audio file
    [audio_data, sample_rate] = audioread([path dir_info(i).name]);
    
    % get length of audio file in seconds
    audio_length_seconds = length(audio_data) / sample_rate;
    
    disp(sprintf('%s length: %.2f seconds', dir_info(i).name, audio_length_seconds));
