Decades before I had the equipment, need, and desire to edit video, I was editing music and audio using programs that were freely available online. Over the years, I’ve been able to create audio for fun as well as fix audio so they can be reused as needed. One client needed an old recording of a family member restored so it could be heard more clearly. Another client had an audio file that they simply couldn’t figure out how to open, so I was able to find the program they needed and send them a file in a useable format. And another client had a bad audio recording of someone threatening them, and I was able to isolate and enhance (like they pretend to do in movies) the audio so it could be clearly understood and used in court to protect the victim.
