Is there a way to open music and play it?

Is there a way for MATLAB to read all music files and work like a music player

[Rahul Gulia]

How can we play Youtube songs links like this? I tried using the webread() function, but it gives me an error "Too many output arguments".

Answer 1

[Anton Semechko]

Yeah, there is a way. Here is an example:

% Get sample audio file from the web
[y,Fs]=webread('http://www.worldnationalanthem.com/wp-content/uploads/2015/05/canada-national-anthem-mp3-free-download.mp3');

% Create a 'player' object
PO=audioplayer(y,Fs);

% Play audio
play(PO)

% Stop audio
%stop(PO)

You can find more info about 'audioplayer' here

[Rainaire Hansford]

what if I wanted to play a song from my computer? Is there a way to play like multiple songs one at a time and control the pause, play, stop, rewind, skip etc.

Thank you

[Anton Semechko]

Use 'audioread' function to load music files into Matlab from disk. After creating the 'player' object with the 'audioplayer' function (as shown above), you can play, pause, resume, and stop. Methods like rewind and skip are not supported by this class, so you will have to implement them yourself.

[Walter Roberson]

For flexibility beyond play / pause / resume / stop, you should probably look at the Audio System Toolbox, which permits you to do streaming-style audio operations. Or you could look at Java.

[Rainaire Hansford]

So if I wanted to use audioread how can I write that in code?

Do you have like an example

[Walter Roberson]

[filename, filepath] = uigetfile({'*.wav', '*.mp3', *.*'}, 'Pick an audio file');
if ~ischar(filename); return; end    %user canceled

fullname = fullfile(filepath, filename);
try
   [y, fs] = audioread(fullname);
   PO=audioplayer(y,Fs);
   % Play audio
   playblocking(PO)
catch ME
  uiwait(msgbox('Could not open that file with audioread'));
end

[Rainaire Hansford]

Hi Walter is there a possible way to give me a functional example?

[Walter Roberson]

[filename, filepath] = uigetfile({'*.wav'; '*.mp3'; '*.*'}, 'Pick an audio file');
if ~ischar(filename); return; end    %user canceled

fullname = fullfile(filepath, filename);
try
   [y, Fs] = audioread(fullname);
   PO=audioplayer(y,Fs);
   % Play audio
   playblocking(PO)
catch ME
  uiwait(msgbox('Could not open that file with audioread'));
end

[Rainaire Hansford]

So the "*.*" is where I have to write the file name of the music?

[Stephen23]

"So the "*.*" is where I have to write the file name of the music?"

No. filename is where you write the filename of the music file.

And filepath is where you write the filepath of the music file.

[Walter Roberson]

The uigetfile() code prompts the user to select a file. If you want to skip that, then store the name of the file (preferably complete with directory) in fullname and then carry on from the "try" statement.

[Rainaire Hansford]

Ok I tried running this code and put in the directory but it was keep given me error. Could some share a example code I might be missing something.

Sorry for taking so long.

[Walter Roberson]

fullname = 'C:\Users\rain\Documents\MATLAB\ProjectGreen\abalone_sound7.wav';     %change as required

try
   [y, Fs] = audioread(fullname);
   PO=audioplayer(y,Fs);
   % Play audio
   playblocking(PO)
catch ME
  uiwait(msgbox('Could not open that file with audioread'));
end

Answer 2

[Rainaire Hansford]

Yes I got it thank you. Now next step is to implement pause and stop and play in this code cause I really need it lol But Walter your the best

[Walter Roberson]

Use play() instead of playblocking() . Then put in a button that uses the pause() method on the audioplayer object.
