Analog and digital sounds or recordings
Compare and contrast the analog and digital sounds or recordings.
Expert
The analog recording is one where the original sound signal is modulated to other physical signal carried on some media or the groove of the gramophone disc or the magnetic field of a magnetic tape. The physical quantity in the medium is directly associated to the physical properties of sound.
The digital recording on other hand is generated by first encoding the physical properties of the original sound as digital information which can then be decoded for the reproduction. While this is subject to noise and imperfections in capturing original sound, as long as the individual bits can be recovered, the nature of physical medium is of minimum effect in the recovery of encoded information.
