Sound editing software that we like includes Adobe Audition (for Audtion, there is a fee). Another option we use at KGNU is, for Macs, Garage Band, which comes for free. There is also free editing software from the web for PC’s, called Audacity. Check around and see what works the best for you. Sound editing takes some practice. If you’re in a partnership with KGNU, we can teach your students and your adults how to use sound editing software, or we can do that part for you. Or you can contact other trainers or read the manuals, and work on gaining this special skill.
