I don't want to replace the existing file instead create a new audio file with the trimmed data, how do I achieve that?

1. I dont want to replace the exisiting file instead create a new file with the trimmed data, how do i achieve that?
2. If I want to read the value from the text field instead of command line, what do i need to change or add ?

Questions 1 and 4 are the same. As I stated previously, you need to use a different filename in your audiowrite code to avoid overwriting the original file.

audiowrite(app.IMPORTEditField_2.Value,y((num_samp*(a-1))+1:num_samp*b,:),fs);
%          ^^^^^^^^^^^^^^^^^^^^^^^^^^^   <- define a new/different name here 

Question 2: Also answered previously. Get rid of the calls to input in your TRIM callback functions. Have it query the values of your START and END edit fields

a = app.STARTEditField.Value;
b = app.ENDEditField.Value;

Question 3: How do you mix two audio files in MATLAB?

well, i followed that bit however, when i press th button i get this. I downloaded a fresh wave file (don't leave me/road)

is it because of the audio that i chose? or a coding bug?

Also, if i try to import any other songs, i am getting the below error( which i didnt experience previously)

Also, I am finding this.

The "TRIM" button was working fine for the forst time it even showed the msgbox which i added and the audio was trimmed.

But after that I am keep getting this:

It looks like the issue is you used text Edit Fields for your Start and End inputs. Replace these with numeric Edit Fields. Name them the exact same thing so you don't have to change any other code.

A = 1:5;
% works
A(2)

ans = 2

% Doesn't work
A('2')

Index exceeds the number of array elements. Index must not exceed 5.

With them being numeric, you can now set the Limits property so that the user cannot specify a value greater than the length of your audio signal.
