Best way to crop an m4a music file
I am working on a slideshow using Photos for Mac. I am using a song in my iTunes library. Unfortunately, it has 4 seconds of silence at the end of the file that I need to cut out. I want to know the best method to use to shorten the file. Should I use garage band? And if so - How?
iMac, OS X Yosemite (10.10.3)
