HOW THE DM-80 WORKS
The DM-80 is possible because of a series of technological
advancements. The most important of these are Digital Recording and
Disk Recording.
DIGITAL RECORDING
Digital recording, popularized by the advent of the Compact Disc,
records sound by storing a series of numbers — a series of digital
snapshots. These snapshots are then played back in series, much a like
a motion picture. The number of snapshots per second is called the
sampling rate. In a CD the sampling rate is 44.1 kHz, which means
there are 44100 sonic snapshots every second. A DAT recorder has
rates of 48 kHz, 44.1 kHz and 32 kHz. The DM-80 can record and
playback at these same rates. The higher the rate, the higher the
frequency response.
