To implement random playback of .wav files, start by adding a private property like audioPlayer to store the audio object and currentFileName to track the currently playing file. In your "Mulai Tes" button callback, call playNext(app) to begin the playback logic.
function playNext(app)
wavFiles = dir(fullfile(pwd, 'your_folder', '*.wav'));
chosenIdx = randi(numel(wavFiles)); % Random selection
app.currentFileName = wavFiles(chosenIdx).name;
[y, Fs] = audioread(fullfile(wavFiles(chosenIdx).folder, app.currentFileName));
app.audioPlayer = audioplayer(y, Fs);
app.audioPlayer.TimerFcn = @(~,~) playNext(app); % Chain next play
play(app.audioPlayer);
end
For the water button, check if app.currentFileName contains an identifier like 'water' using "contains". If it matches, stop the audioPlayer and call playNext to force the next sound:
function WaterButtonPushed(app, ~)
if contains(app.currentFileName, 'water') % Basic filename check
stop(app.audioPlayer);
playNext(app);
end
end
To enforce 3 plays per sound, consider tracking play counts using a variable. For more details on "audioplayer", refer to the documentation: https://www.mathworks.com/help/matlab/ref/audioplayer.html.
