I've found that device in "DSP-Speakers" on http://www.wimo.com (you must
navigate to the "Radio accessories" page). They have demo sound files (20m
and 40m CW).

Here is a link to one I tried (sounds promising):

I've made some tests tonight with EZKIT-LITE (Analog Devices ADSP2181
evaluation board) and DSP-10 (2-meter transceiver,
http://www.proaxis.com/~boblark/dsp10.htm) software. The software can be
used with the bare EZKIT (no RF hardware needed) and is quite capable. It
has various band-pass filters, de-noiser and, what was the most interesting
for me, binaural mode. In binaural mode one channel is delayed by 20ms (user
settable). The result is that the noise appears all around you (not in your
head) and the signal is in front of you (not in your head), halfway between
the center and the right side (or left side, depends on how your earphones
are connected). It's quite an experience, but one must get used to it (which
I did tonight during the RU DX contest).

De-noiser is useful, but I guess that it's much more useful on VHF and UHF
where the noise is more uniform.
