Schaack Audio Technologies has updated Quad to v2.20 for both Mac OS X and Windows. Version 2.20 introduces a completely rewritten iTunes-like search function driven by a new Database system that allows you to edit metadata (tags) for any audio file format. It also includes a new EQ-type called Isolator and some small bug fixes and other new features.

New in Quad v2.20:

• Database-driven Browser with fast iTunes-like search feature.
• AudioUnit & VST hosting for Mac OS X.
• New Isolator EQ type (analogue modelled).
• Drag'n'drop from iTunes/Finder/Windows Explorer.
• Minor bug fixes.
• No license file needed anymore.
