Object for playing audio - MATLAB

https://www.mathworks.com/help/matlab/ref/audioplayer.html

Use an audioplayer object to play audio data. Sampling frequency in hertz (Hz), specified as a numeric scalar. Valid values of the sampling rate depend on both the sample rates permitted by MATLAB ® and the specific audio hardware on your system. MATLAB has a hard restriction of 1000 Hz <= Fs <= 384000 Hz, although further hardware-dependent restrictions apply.

How to use the audioplayer timer function with a GUIDE GUI

How to use the audioplayer timer function with a GUIDE GUI. I designed a GUI with GUIDE that plays an audio file and plots its waveform. I then wanted to go a little bit further and add a line that tracks across the waveform as the file plays. I know in principle that I can use the "currentsample" property of audioplayer and a callback function ...

filename = 'myAudioFile.wav'; [y,Fs] = audioread (filename); Now, you can use the audio player to load (and later play) the audio as. player = audioplayer (y,Fs); We want to play the audio with a fixed delay, so we create a function that our timer will call. function playAudio (hObject, eventdata, audioPlayer)

Note I changed the r.TimerFcn to use samples{k - 1} instead of k because k will increment before the timerfcn gets called. So this might give you issues with your first sample, you'll have to tweak it a little. Also this is an infinite loop, which I'm sure you'll want to address.
