A very common operation is to convert a sound from one format to another one, for example to encode a song from a CD to either Mp3 or M4a or to create FLAC files for archiving. Just open the sound into Amadeus Pro by using the Open command from the File menu or by dragging the icon of the sound you wish to convert from the Finder onto the Amadeus Pro icon in the dock.
Then select Save As from the File menu and select the desired destination format in the pop-up menu located at the bottom of that dialog. You may optionally wish to tweak the settings associated to that particular format by clicking on the Settings button. See Section 3 for a description of the various formats and the settings that go with them.
