You can get the new version here.
Changes from 0.01
-Changed name to “RJDMC”
-Any .wav input rate is supported and properly conveted to 33144hz
-Drag ‘n’ Drop is supported
-Added an Edit->Preferences menu for batch processing
-Allowed opening multiple files for batch processing
-Multiple .wav output rates
Batch Processing: If you want to process more than one file at once, first go to edit-> preferences and choose your output method (this will not work in “manual” mode as that expects one at a time). After selecting an option (and a .wav output rate for .WAV output if you want), either drag/drop multiple files onto the application or use the File->Open dialog and select multiple .wav files. They will automatically be created in the same folder as the input files with either “<inputname>.dmc” for DMC output or “<inputname>D.wav” for .WAV output.
