The demonstration of the Copy Code you refer to was made by the
Home Recording Rights Coalition (HRCC). They have a tape (cassette)
with the demo on it. The demo also includes a swept tone passed through
the filter. A comparison of the sound with and without the filter is given.
The effect of the filter is extremely noticeable, however CBS contends that
the filter used did not comply to their specifications (a likely story).
The HRCC's address if you don't already have it is:

		Home Recording Rights Coaltion
		P.O. Box 33576
		1145 19th Street N.W.
		Washington, D.C. 20033

Has anyone thought that there might be an alternative motive behind CBS copy
code? I doubt that the record companies are losing as much as they say they
are. I think their additional motives may be is to kill DAT for two possible
reasons:
(1) They have invested alot of money in CD pressing plants and don't want
    competition from DAT's
(2) A DAT machine allows a musician to make high quality tapes without the
    need for CBS to produce him/her.
