Matlab 7.1 Official

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

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

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: matlab 7.1

% Note frequencies (Hz) - C major scale notes = [261.63, 293.66, 329.63, 349.23, 392.00, 440.00, 493.88, 523.25]; note_names = {'C4', 'D4', 'E4', 'F4', 'G4', 'A4', 'B4', 'C5'};

% Musical Piece Generator for MATLAB 7.1 % Creates a simple melodic phrase and plays it clear all; close all; clc; % Time vector for one note t =

% Normalize to prevent clipping audio_signal = audio_signal / max(abs(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]; round(0.02 * fs))

% Initialize empty audio signal audio_signal = [];

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

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

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