how to sample an audio file ?

Answer 1

[Walter Roberson]

[data, fs] = audioread('name_of_file_goes_here.wav');

num_seconds = 1;    %does not need to be integer
sample_length = floor(fs * num_seconds);
sample_start = randi([1, size(data,1)-sample_length+1]);

sample = data(sample_start:sample_start+sample_length-1, :);
