EdLib a tiny little player for Vibrants' EdLib music (also known as D00 files). This is a format that was used for music created on the PC for AdLib sound cards. If you enjoy SIDs, you'll find many similarities between C64 music and D00 music.
EdLibPlay uses an emulation engine that tries to ensure a high-quality rendition of the original AdLib chip (Yamaha YM3812 chip) sound. The GUI is simple with no frills.
Requires Mac OS X 10.4 or higher, runs on PowerPC and Intel-based Macs.
Oh and by the way, the EdLibPlay package also includes a collection of nearly all available D00 music files for your listening pleasure. With proper filenames and headers.
