[Elecraft] Is DVR audio really getting equalized and compressed?

[Guy Olinger K2AV]

I think a part of the problem is the use of a very indistinct term,
 "lackluster", which could refer to low volume, frequency response, desired
artifacts of compression, etc.  Can you be terribly specific and technical
about what you mean by lackluster?

It has been a measured fact since the middle 20th century, that people do
not hear either highs or lows as well as midrange when the volume is low.
 This lead to the addition of a "loudness" setting in stereo amplifiers
which artificially raised the level of lows and highs to have the same
PERCEPTION of full frequency range at quieter listening levels.  Not
surprisingly some found the sound harsh at higher volumes when the
"loudness" was engaged.

If you have your monitor level set low for DVR playback, and you have normal
human hearing, you WILL hear LESS highs and lows.  Comparison of two results
for sound "spread" and "brightness" must be done at equal volume levels, or
your ears will deceive you.

73, Guy.
