There are editing features like cut, copy, paste with undo and redo support for them. There are also filters to process the audio data and analyzers to analyze the data.
You can start the audio editor by typing AudioEditor at the command prompt.

Hi. When I try to run AudioEditor.m I get the following error:

AudioEditor:File Reader
"Expected input number 2, range, to be an array with number of columns equal to 2."

The edit will still come up but I get the same error when I try to read a .wav file.

Ideas? Thanks.

hi navan, is it possible to compare two signals and to estimate their similarity using your program?

Selection code is in axesButtonDownCallback method. You can instantiate AudioEditor in a function and simply return the value.

tan, Are you building your own ui with copy paste functionality? Look for cutCallback, copyCallback and pasteCallback in AudioEditor.m to see how they are implemented. You can create a function which creates and returns AudioEditor.

Currently command line inputs are not supported by AudioEditor. The class is there only to create the GUI and everything else is done through the UI. You can add a filename input as an argument to the constructor by modifying the AudioEditor class. You need to assign

this.Filename = varargin{1};

as the first line in the constructor.

Hello again. I'm new to user defined classes and I've been having difficulty understanding how to start AudioEditor with a file already in a function as opposed to loading it from the 'Data' tab in the GUI.

Is there a way that I can just assign 'Filename' in 'varargin' in the constructor function? From what I've read that function creates an object, 'this,' of the class but I don't understand what it's doing with 'varargin'.

I've been playing around with the 'Filename' property using uigetfile and it works when calling AudioEditor from the Command Window but not from within a function. I always get the answer, "AudioEditor with no properties."

Lastly I tried setting the 'Filename' with "AudioEditor.Filename = 'test.wav'" before calling 'AudioEditor' but that just resulted in an output of "Filename: 'test.wav'.

Should I be looking to modify 'getFromMATLABVarNameandFs.m' to accomplish this?

Also, could you explain the difference between Filename, AudioData, and filename?

Thanks for your help,

Thanks! That did the trick.

In the file AudioEditor.m change the line "load audiotoolbaricons;" to "load uiscope_icons;". That should fix it.

Hello Navan, thanks for the program.

I'm receiving the error: "Unable to read file 'audiotoolbaricons': no such file or directory."

Do you have any suggestions on what I need to do to point to this?

Thank you.
