Digital vs. Analog Audio Signals Recording Media
|
Objective |
| Audio
signals have been recorded for almost a hundred years. Edison first
recorded audio signals on metal drums. From there we have traveled
through phonograph records pressed out of vinyl, magnetic recording
tape that doesn't have the same mechanical limitations of phonograph
records (namely, they don't wear out as quickly) and finally to digital
audio tape, compact disks (CDs), and MP3
media. The final three media are special not only for their use of
different media, but for their method of storing music. All digital
music is sampled and then stored as data in memory. When played back,
digital music must be read from memory and then reassembled back into
analog audio. Devotees of digital music feel that the re-assembly
of the signal back to the original analog audio insures fidelity,
while many purists find this to be its biggest drawback. The personal
taste of the individual will always be the final judge. |
