Matlab 7.1 💫

% Add short silence between notes (optional) silence = zeros(1, round(0.02 * fs));

% Time vector for one note t = 0:1/fs:duration-1/fs;

% Initialize empty audio signal audio_signal = [];

% Melody: sequence of note indices (1-8) % Simple melody pattern: C - D - E - C - E - D - C melody = [1, 2, 3, 1, 3, 2, 1, 5, 5, 6, 6, 5, 4, 3, 2, 1]; matlab 7.1

% Parameters fs = 8192; % Sampling frequency (Hz) duration = 0.5; % Duration of each note (seconds) tempo = 120; % Beats per minute

% Play the sound (MATLAB 7.1 compatible) sound(audio_signal, fs);

% Generate the piece fprintf('Generating musical piece...\n'); % Add short silence between notes (optional) silence

% Musical Piece Generator for MATLAB 7.1 % Creates a simple melodic phrase and plays it clear all; close all; clc;

Since MATLAB 7.1 (R14SP3, from 2005) has limited audio and synthesis capabilities compared to modern versions, here's a piece of code that generates a simple and plays it:

fprintf('Note %d: %s (%.2f Hz)\n', i, note_names{note_idx}, freq); end round(0.02 * fs))

for i = 1:length(melody) note_idx = melody(i); freq = notes(note_idx);

% Optional: save to WAV file (if needed) % wavwrite(audio_signal, fs, 16, 'my_musical_piece.wav'); % fprintf('Saved to my_musical_piece.wav\n');

% Append note to audio signal audio_signal = [audio_signal, note_signal, silence];

% Create sine wave with envelope (attack + decay) envelope = exp(-3 * t / duration); % Simple decay envelope note_signal = sin(2 * pi * freq * t) .* envelope;
