[Elecraft] NR settings at AD4C K3 now available at my website

[Matt Zilmer]

I'm still evaluating the NR settings here.  On strong SSB signals, it
sounds OK to me, but seems to limit or compress weaker voice signals.
I've been pleased with the improvement to CW signals, though the
settings available don't seem to change output characteristics much on
a strong CW signal.  Probably no surprise.  Intelligibility is much
better on F1-1 with weaker CW signals.

MP3 files aren't necessarily the best way to hear voice.  The masking
(or compression) is pretty good for rock music, but tends to cut out a
lone voice.  Or "classical" music, which gets cut down a lot in terms
of the dynamics.  MP3 probably works well for CW though.

For voice comparisons I've done / seen in the past, WAV files work ok.
Does anyone have more input on MP3 vs WAV?
