#1.For the script to work please put your audio files and image files in the same directory#
#2.They should follow the format FileName1.mp3 , FileName1.jpg
#3.mp3 , jpg and whatever formats you include in the filters will be supported
#4.ffmpeg should be present on your machine

#location of audio and image files to be combined
$input_directory = "C:\Users\gaba\MyFiles"
