Within the DSP setup in the O2 (and probably the other TT DSP radios) we can
select the number of "taps," which I think sets the number if samples or the
sample interval.
I played with that some time ago and, while it was a bit buggy for certain
selections, it changed the timbre of the recover audio. My personal impression
was that it tended to sound "more analog."
This isn't completely OT, because the discussion centers around how pleasant
the Corsair II audio sounds. Has anyone else played with the number of taps
within the DSP set up and come away with similar impressions?
