** Please note, this software is new, and still in beta. If you encounter issues, please let me know. **

Drag the BWAV files you would like converted on to the App. MP3 files will be created in the same folder as the original files. Alternatively you can open the app and select files from the browser window that opens.

If you encounter issues using this software, please contact me and let me know. I do not actively maintain this software, and I make no guarantees, but I will do my best to help if I’m able. Contact me at:

Thanks to the FFmpeg, BWFMetaEdit, and XMLStarlet teams for developing such great utilities.
