Optically isolated audio cable

[Adam Sargant]

Does any one know of a manufacturer/supplier of optically isolates
audiocables that I could use to connect a small biofeedback device that
generates a tone to the microphone input of a PC?

Thanks in advance for you help

DO you absolutely need optoisolation ?

Would just an audio frequency isolation transformer be
suitable for your application ?

eep... I don't know, I'm no electronics engineer, though I do know one

I'm working on a piece of software that would interact with the galvanic
skin response expressed as an auditory tone, and the easiest way I could
think of doing this was to plug the (already comercially available) GSR
device into the line in or mic in of a pc... but I am advised that if the
application is ever to be commercially viable (it may not be, that's a long
way down the line) I would be required to isolate the GSR device from the
PC, for the obvious reasons... if there is another way of doing it, I would
be grateful for any references.

Way out of my cost league, but thanks for the response

What's the output of the GSR device?

Analog? Perhaps you could digitise it using a battery powered PIC (or
similar and have the PIC output TOSLINK.
