sound will not play Mac Matlab 2018b

11 次查看(过去 30 天)
Hi there, I am working through a brilliant Udeny course in Matlab and am currently working on generating a sound but am finding that this session does not work, even though I have written exactly as specified (I think!)
frequencies = 5000; % Hz
duration = 1; % duration of the sound
amplitude = 1; % loudness
fs = 44100; % Sampling rate
T = 1 / fs ; % Time sampling period
t = 0:T:duration; % time vector
signal = amplitude * cos(2 * pi * frequencies * t);
sound(signal, fs)
Can anyone tell me where I'm going wrong please?

MATLAB Online is at
http://matlab.mathworks.com
Not all licenses have access to that, but current student licences do.

Thank you everyone, I trashed my file, and then emptied it, and the sound is now playing.

The issue is most likey due to having multiple user-defined sound.m files.
Replace sound(signal, fs) with the following code
player = audioplayer(signal,fs);
play(player)
If it is playing for the above code, execute the following line
which -all sound
If it returns more than one sound.m location, rename all the sound.m files in location other than MATLAB builtin path which ends with toolbox\matlab\audiovideo\sound.m

By the way, I'm running MATLAB R2018b, on a Mac, OS 10.14.6 Mojave...
