Recently, I saw an oscilloscope screen capture of digital and vinyl signal =
in a forum. The vinyl signal as expected was wobbling and jittery. It was c=
oncluded for that reason that digital playback is more accurate representat=
ion of real sound as it preserves and plays back the original signal almost=
unaltered.


However, in real life, how much of vinyl signal is distorted compared to th=
e actual sound waves arriving at the ear's canal? We are talking about the =
most fluid medium (air) that stands in between our ears and the source. Unl=
ike a wire, the air that transmit the waves to our ears relies on the vibra=
ting particles of air. The air's density varies every inch. It is the most=
unstable medium to transfer any audio signal accurately. Signal reaching o=
ur ears may very well be wobbling and jittery like seen in the oscilloscope=
..

A simple speaker's measurement of loudness itself reveals at any other dist=
ance of 1 meter it varies so much that the measurement becomes so much mean=
ingless for a proper evaluation of speakers. That's exactly the reason why =
some manufacturers are not publishing the technical specs other than what's=
can be measured by point to point wired measurements. That medium (wires) =
is stable and repeatable but not the measurements involving signals traveli=
ng through the air which varies with temperature, pressure, wind and many o=
thers factors.

We are actually listening to wavy, wobbly and jittery signal all the time. =
That's natural. Vinyl signal maybe be distorted but it may be the correct r=
epresentation of the way real signal reaching our ears or at least make it =
as close as what actually reaches our ears in live sound.
