The best converter of several I have tried
I have used AVC pro for a couple of years. I have found it extremely useful for converting .wav sound files created with "Audacity" to .mp3 files which reduces the file size. I have also found it extremely useful for converting video to MP4 format which i use in PowerPoint presentations for talks and lectures I give. It took a little while to learn how to use it and select the correct conversion options as for me the display was not immediately clear on what to do. I create sound effects for our village Pantomime and AVC is really invaluable in enabling me to convert various formats to mp3 to run in the specific sound effects programme we use for the Show. I highly recommend AVC software.
