After having read the interesting thread about binaural CW and pseudo-stereo
I found these two descriptions of analog circuits that are fairly simple to
build. The most advanced one is by VE3VXO:

Hello Sverre,
It would be nice though to find a TDA3810 pseudo-stereo IC and build a
circuit around it as Benny, OH9NB, suggested a couple of days ago.
A (not the) source for the TDA3810 is Segor Electronics (www.segor.de) in
Berlin/Germany. Type in TDA3810 in the upper left corner and mark
The AOR TDF-370 is now out of production but had a binaural filter. The review
in the September 2001 QST said that the CW Stereo function made a huge
difference.
Take a look at

Lastly, I do know that there are at least one current amateur radio
transceiver with binaural CW reception built in perhaps more than
one.
Orion I, Orion II and the SDR-1000 all have
binaural audio. I operate a lot of CW contests and have not
found binaural to be very
I have done a couple of Binaural CW reception projects and found the
results very appealing. Let me begin by sharing a few thoughts:
1. With binaural reception you normally would NOT use tight CW
bandwidths as the object is to allow more audible information to
be processed by our brain. I think

My second project began with the following in mind:
1. Using band-pass filters rather than low-pass and high-pass.
2. Include the ability to move the combined filter cross-over for
different CW offsets.
3. Get
