difference between analog and digital music?

Question

difference between digital and analog music procesess?

Answer 1

Vinyl records and magnetic audio tapes use analog processes, which work by having physical variations in the recording media transmit the information from the audio wave. While these formats often have greater range with no cut-off in the low and high registers, they tend to wear out over time and with regular use. They also will result in a loss of signal when re-recording, such that there will be a noticable difference in quality between a 1st generation copy and a 7th generation copy that originated from the same source material. CDs and portable music players use digital formats, which are basically just stored the same way as a computer file, as a series of 1's and 0's. Copies upon copies upon copies will not change the quality of the data unless the recording process fails or is interrupted, resulting in either a corrupted or incomplete file.

It's kind of like copying text from a source. Photocopying it is like the analog process, where a photocopy is never quite as good as the source that it came from, losing clarity because of incorrect light/dark settings, because dust was present in front of the copy, or because imperfections in the original paper or the photocopier result in visible artifacts being transferred that weren't noticable on the original. The digital process is more like just rewriting the text. It doesn't matter what it looks like, the information contained is still (theoretically) the same no matter how many times it has been recopied or how bad it looks, and you can always make a clean copy from a sloppy one.

Answer 2

The key difference between analog and digital technologies is that analog technologies record waveforms as they are, while digital technologies convert analog waveforms into sets of numbers, recording the numbers instead. When played back, the numbers are converted into a voltage stream that approximates the original analog wave.
best thing about digital music is that it doesnt matter how many times you copy it, it is always the same.
when copying analogue music the quality deminishes every time you copy it as it pics up more static or noise.
