The UAD-1 Project PAK from Universal Audio consists of a short form PCI card for use in both Mac and Windows based computer systems, along with five bundled plug-ins that range from dynamic processors through EQs to reverbs. The card also provides dedicated DSP for various other manufacturers' plug-ins, to run under VST, Audio Units or RTAS compatible software.
The UAD-1 Project PAK contains exactly the same UAD-1 card as the other packages based around the UAD-1 and delivers the same performance and quality previously limited to high-priced digital audio workstations. It features a super-DSP chip with a proprietary audio engine and unlike other DSP cards (which juggle DSP tasks between multiple chips,) the card uses a single, non-partitioned processor, allowing for more sophisticated plug-in algorithms. Because the plug-ins run on the card itself, the computer's CPU has more headroom for other functions, including additional tracks, mix automation or more native effects.
