Thank you gmayor.

I copied and pasted the above code into Microsoft Word's VBA by Alt+ F11. Then I copied the path of the .mp3 placed on the desktop to the code. After I run the code, there is no start time and end time shown in the Word processor.

And I have another question:

Can the macro read and output the .m4a file's start time and end time, if the .m4a file's start and end time is according to the time of recording? (For example, the start time and end time of a .m4a file is 11:00:00 am to 13:00:00 pm, not 00:00:00 - 02:00:00)
