I have been playing around with feeding differently derived audio into the two halves of stereo headphones with some interesting results. I will report in detail when the tests are complete. In short, it is certainly possible to improve headphone reception, both in terms of close-in selectivity and resistance to static.

One question. How do I make an electronic circuit to delay a broadband audio signal by about one-thousandth of a second, without resorting to DSP? Any genius out there with a simple circuit? And yes I do know about the methods (that were originally used for electric guitar echo) such as connecting the diaphragms of a loudspeaker and a microphone by using a spring, and also the tape recorder method.

The method we used at a TV station I once worked for was to use a long
corridor with a mic and a loudspeaker!
