The supported formats are AAC, AC3, AIFF, APE, AU, FLAC, M4B, MKA, MP3, OGG, RAM, SPX, WAV, and WMA, among others. To convert them, all you have to do is drag and drop them into the program window, and click the convert button.
The program options, unlike the supported formats, are very limited, as they won't allow you to set any measure of quality. The only thing you can change is the program appearance--and, of course, you will have plenty to choose from.
Free Audio to Flash Converter is an exciting app due to the peculiar formats it converts. If you ever need a song in flash, this is the program.
