On a clean vinyl disc or a tape played with dolby or some kind of compression/limiting...?

There are several points in that question.

"Live" means As-it-happens-in-real-time, as in watching a sporting event live.

Or, with music, a "Live Album" is a recording of a Live performance (as opposed to an album made up from edited sections recorded in a studio).

Live albums and Studio recorded albums are totally different things; I don't know if that is where some of the disagreements originate.

Re. recording & playback: Technically - and obviously to most people - there are always differences between the original and any reproduction of a live show.

The first and most obvious is the acoustic environment. At a live performance you can turn your head and hear the differences with the sounds echoing and different ambience from different areas. A good surround system can emulate some of that effect, but with a limited number of speakers in a few fixed locations, it's never the same as a true theatre- or stadium-size live performance.

Also, there is always some degradation in a recording and playback process using analog elements. It may be very close but it is not _exactly_ the same.

(Actually, virtually any commercial "stereo" recording played back through a normal stereo system has serious quality degradation, as they are almost always surround encoded and without being fed through the correct surround decoder and speaker system, sounds from different directions are mixed, reducing the clarity and separation of the "stereo" output.)

I'm not sure whether you are just expressing yourself badly but you seem to be very badly informed and confused.

In the case of most recordings meant for entertainment, there is NO attempt made to make the final tecording sound like the actual performance. If that was the intention then the main limiting factor would be how the tecording was reproduced. Considerably more than a pair of stereo speakers would be required.

The asker is poorly informed,

has poor communication skills,

and is belligerent.

That's a recipe for not having any further questions answered.

This question makes no sense.
