The new remasters often sound more detailed. It's not dynamic range compression, although there is often plenty of that too. I used to be ambivalent about original CDs or remastered CDs, but have confirmed digital remastering sounds better sometimes.
There's too much dynamic range compression when the volume can't be turned up to decent levels, because continuous power is overloading the ears (on decent hi-fi equipment, not mastered to compensate for loud background noise).
Makes sense if there is a lack of such tests. It is the same principles as other digitized line level signals. ADCs with minuscule distortion in specifications and linear frequency response cover such tests you are asking about...
The fallacy of composition is an informal fallacy that arises when one infers that something is true of the whole from the fact that it is true of some part of the whole.
There is a certain volume of air in the room that needs to be filled with acoustic sound. Dynamic range compression is a way to do that and can make details of music easier to hear. This will usually involve speaker interaction with room acoustics, on the other hand the compression can...
