This program is a handy little tool for converting WAV files to the AIFF format, as well as back from AIFF to WAV.
What sets it apart is that it not only converts the raw audio data, but also parameters such as root key, pitch, and key/velocity/loop ranges. It supports 8-, 16-, 20-, and 24-bit files in both mono and stereo.
The application was developed in Swift 5.5.2 and built with Xcode 13. It should therefore run without any issues on macOS 10.10 and later. It also natively supports Apple Silicon and runs on all current versions of macOS.

Here’s how the app works:
Simply drag one or more WAV files into the program window. Without prompting, the program will begin converting them to AIFF format. The converted files are saved directly in the source folder of the original files.
Normally, the program does not overwrite existing files but instead appends a number to the new filenames. However, there is also an option on the interface that allows you to force overwriting if you intentionally want to overwrite the destination files.
There is also an option to always save the destination files in a corresponding AIFF or WAV subfolder.
Please note that this software is specifically designed to convert files for hardware or software samplers. Therefore, some additional information (ID3 , bext, etc.) is intentionally excluded from the conversion.
