Help with compression and dynamic range


I'm 51. After a 15 year period of dealing with mortgage payments and childcare needs, I'm trying to get back into higher-end audio quality - especially when it comes to dynamic range in concert DVDs. I've recently spent countless hours trying to research CDs, MP3s and compression issues - with no resolve.

How can I tell which concert DVDs offer wider dynamic ranges? Or, for that matter,CDs? Is there a rating on the covers? I'm willing to do my homework if anyone can give me a reference. I've just read "Get Better Sound" by Jim Smith with no resolve.

Also, I'm looking to purchase a DVD player which will maximize sound quality when I can determine which DVDs and CDs are recorded with minimum compression and wider dynamic range. Can anyone explain what to look for when purchasing a higher-end DVD player. I've seen ratings for DACs, but am unsure what they mean.

ANY help is appreciated.

Different strokes for different folks .
What I am referring , to by whatever term , is indeed very real .

" With anything approaching a full range musical passage that level of bandwidth limiting would sound unnatural. "

And that sir is exactly what I have been describing !

But compressing is not limiting the high frequencies or the low frequencies. It is raising the volume of all frequencies of the soft passages of a song so the volume equals that of the loud passages of the song.
Ok , I'll bite . Just to get this thread back on course to help the original poster .

What do you call the act of limiting the high and low frequencies ?
"What do you call the act of limiting the high and low frequencies ? "

I'd call it "filtering".

The term compression relates to dynamic range. It should be easy to verify this with a good Google search. I'd start with Wikipedia.
But you are the one who took the thread off course Saki by creating your own definitions to common audio terms. You're making it sound like you're being the moderator and getting things back on track when it was you who caused the derailment to begin with.
