there are better converters than this

Conversions (WAV to m4a) are coming up with error messages- ‘this file is damaged and can’t be opened’. The damage happens during the conversion, the original remains fine. Also, Yosemite doesn’t allow me to open files from ‘unidentified’ developers, prefering developers that come from the Apple Store. I purchased this app from the Apple Store and STILL receive the ‘unidentified developer’ warning. I wish I did not purchase this app.
