I'm trying to extract information from a sound file in order to use it in a video classification algorithm I'm working on.
My problem is that I don't know how to work exactly with audio files in matlab.
Below is what I need to accomplish:
-open the audio file and get the sampling rate/frequency.
- I need to work on a window of 2 seconds so I have to loop over the file and get each 2 sec as a window and then do the ftt on each window.
After that it is my turn to use these values to do what I want
any help would be appreciated
