Another suggestion might be to reproduce, with a single audio tone for *visual* detection, the same effect that the sweep tone gives the ear - that of a very definitive pattern that changes like no other random pattern would. Perhaps the pattern of the tones could start fast (5 dashes/sec) then gradually lengthening until they were one dash lasting 5 seconds, with the whole string lasting for a minute. On a spectrum display, at some point in that minute you should be able to tell you got the pattern. Also, that pattern should be audible to the ear, giving it the added benefit for those without spectrum analysis capabilities, Brett Saylor _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
