Analogue vs. Optical the difference

In theory sure, you can come close, but in practice, its very hard to do a analog recording that will match the digital. Analog recording often have much thinner bass and slightly lower max volume. If you're using a Sony player/recorder that means your stuff will sound somewhat lame compared to a CD.

Digital give you an exact copy of the original recording - no volume problems, no weirdness. Its much closer to CD quality with nothing to tweak or stress about, except to hit the "record" button. Why mess with analog?

Half of my collection is recorded analogue (I just didn't have the digital option for a while), and they sound fine. After a little practise, you get a feel for the levels, and though the sound is different, it's no better or worse. Some points in analogue's favour: all the levels are the same; I don't have 'quieter' recordings followed by 'louder' recordings on the same mix and I can dub digitally off my analogue MDs.

I know you can adjust the digital record level, too--I'm just lazy these days.

Actually, there is a clear difference between the two. 90% of my collection was recorded in analogue due to my lack of an optical CD player. And altough they sound great, when I purchased my PS2 and utilized it's opitical out, I was astounded and somewhat socked when I made my first digital recording. On a quality stereo, the music sounds noticably "cleaner", "sharper" and more "crisp." What I mean by this is that the treble is noticably more clear and sounds less "muffled." Even with Sony's 24bit D/A converter, (which does a great job in analogue recording) you can clearly hear the limitations of the D/A converter when you skip it altogether in digital recording. Bass is also noticably more crisp as well. A great way to check this for yourself is to record Linkin Park's "Hybrid Theory" in analogue and then in digital. As stated, on a quality stereo, you should very cleary be able to tell the difference.

I've actually gone back and re-recorded (in digital) some of my albums that I still owned the original CD's for. All this was done on my MDS-JB920 (and my MDS-JE510 '97 - '00).

It can depend on what sounds better to you. Analog recordings can sound "warmer" and "airier" than digital recordings, depending on the quality of the D/A converter of your source device. If you have a sound card that can play back 24-bit audio and you use foobar2k to play it back, adding 24-bit ATH-based dither can give you an extremely clear, noise-free recording. By the same token, using a low-quality sound card can give you really thin-sounding analog recordings.

At the risk of sounding like a heretic, given good equipment and recording, a little D/A-> A/D in your signal path isn't a bad thing at all.

Digital is definitely more convenient, though.

I do agree with you that analouge recordings do sound "warmer." That is--if it remains in the analouge world (unless the analouge source is connected to a very high sample rate ditigal recorder..like SACD). If I were to record a symphony with great digital equipment and put it on a MD or CD, it would sound great. However, if I were to do the same recording with very high quality analouge equipment, it would sound more "natural."

Nonetheless, I love recording in both modes, depending on what I'm recording.

:shock:

i think the topic is "analog" &"optical",but we were all discussing the "digital",so we all ignored D/O(digital to optical)&O/D,the siginal would be weakened when this change happened,although it also sounds like the digital recording,but it got worse than the digital.the really digital recoed is just in decks.

its basically the same thing when talking MD recorders. Optical to me is alot better than analog. analog sounds like crap to me. but the only thing ive ever known with my minisdisc is optical

NRen2k5 is right. The point of making a digital recording from a digital source is to maintain signal quality. With digital, you aren't transferring a wave like you would with analog, instead you're transferring 1's and 0's like your computer would if you were downloading a track off the internet or something of the like. Sometimes the 1's and 0's aren't transferred perfectly, but when that happens it very rarely results in any kind of change that we can perceive.

As for "digital to optical" and the reverse, there is no such thing. Optical is digital, it's simply a method of transferring the data. Optical lines carry 1's and 0's from one device to another, nothing more.
