While you do have a point, MP3 does meet the digital definition of
compression.
That IS the speech defect I am talking about!
If that IS the new definition that definition is plain wrong and
misleading. Never before in no other branch compression ever meant
throwing away data or material.
Um... it's not exactly "new". The term "compression" for what is
essentially data reduction has been in use since at least the 80s,
perhaps earlier.
So while you have a valid point, it's about three decades too late to
fight this linguistic battle.
Try a lot later than that.
Data reduction techniques have been used in audio for a
long time. And they have been used in music, even "high-
quality" music, for some time as well.
Strictly speaking, techniques such as dBx and Dolby A, Dolby
B and such, are all data-reduction compression techniques.
Their purpose is to attempt to fit as much of the "important"
data into a naroowed-bandwidth channel, be it a transmission
channel or a cassette tape. They all work on the smae principle:
they (physically) discard information which, in the eyes of the
designer, are deemed "insignificant."
And, if you want to play the linguistics game, while still being
technically accurate, the human peripheral auditory system
imposes HUGE amounts of lossy data compression. While it is
possible for the human ear to discern sounds ranging over
a power range in excess of 12 orders of magnitude, it CANNOT
hear, at the same time, two sounds whose level differs by that:
in fact, the instantaneous dynamic range of the peripheral
auditory system is FAR less than that, by many orders of
magnitude. And it does it, through among other things, masking.
