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.
