Cedar is a computer-based audio restoration process that is a software 
on a PC platform but requires some very expensive purpose-built 
hardware.  The concept was originally conceived by Lloyd Stickles when 
he was chief engineer of what was then known as the British Institute of 
Recorded Sound (I was just looking at some videotape of Lloyd's first 
presentations about it at ARSC and IASA back in the 80s.)  Creating the 
process was entrusted to a team at Cambridge Univ, and during the early 
years of what we now consider low-capacity computers it took several 
minutes to process a second of sound.  You let the computer do a record 
side overnight!!! 

There was a similar system introduced a couple of years after the first 
Cedar called No-Noise by Sonic Solutions, and it was too easy to 
over-process recordings using this system.  I'm not sure it is still 
around -- I don't recall seeing credits for it in recent years.
