Technology Background
Edison's Phonograph
Thomas Edison’s brilliant phonograph invention captures the physical oscillations of analog sound, representing them via a corresponding continuous signal path carved in a wax cylinder.
For playback, a stylus rides a groove and follows its continuous path regenerating the original oscillations that carved the groove.
Vinyl Groove
There is a direct relationship between the oscillations of the sound wave and the movement of the stylus following the groove.
Physical movement of the stylus assures a signal of a continuous nature as there is no quantization in the path between adjacent signal points.

Filling the Gap
Filling the Gap
In digital music, no matter how high the sampling frequency, there must be a mechanism to connect adjacent samples for a smooth continuous signal.
