visualize music in matlab

To visualize music in Matlab, we can use the signal processing toolbox to create a spectrogram, which is a 2D representation of the time-varying frequency content of a signal. Here is an example code snippet to get started:

main.m
% Load music file
[y, Fs] = audioread('music.wav');

% Create spectrogram
win = 512; % window size
noverlap = round(win/2); % overlap between windows
nfft = win; % FFT size
spectrogram(y, win, noverlap, nfft, Fs, 'yaxis');
223 chars
9 lines

This code loads an audio file called music.wav, creates a window of size win=512 samples, with noverlap=256 overlapping samples between windows, and performs a nfft=512 point FFT on each window. The resulting spectrogram is displayed with frequency axis labeled on the y-axis, and time on the x-axis.

You can try experimenting with different window sizes, overlaps, and FFT sizes to achieve different levels of time and frequency resolution.
