Dynamic music, okay, I think I know but not sure if my dynamic is the same as your dynamic.

The difference between quietest and loudest passages in music typically 6 to 10 dB. But maybe it could be a contrast between bass & highs.

What does dynamics in music mean to you? Give song example, please.

You are correct dynamic range:

6 to 10 db? What kinda of db? Answer that and that's my dynamics.

I recall using Pink Floyd-DSOTM. Sacd has a dynamic range from 70 dB to like 110 dB. Cd was something like 80 to 98 dB. DTS was somewhere in between, vinyl of course which I don't have would be less than cd.

But there is very few albums where the dynamic range will jump more than a 6 dB spike. An exception I can think of is a cd I have by Koto. You play it, but you can barely hear it, so you turn up the volume then all of a sudden the dynamic range jumps and nearly blows the speakers scaring the hell out of you. That's why I don't play that cd.

And you know in a car you can't hear the quiet passages of a cd with dynamic range because of road noise. Which is why compression works for the car but not home audio.

Typically 'dynamics' would be crescendos and contrasts between bass, mid-range and treble within the 6 dB range, IMO.

Maybe you have a more definitive explanation?

I think this is complete misinformation. In my experience, vinyl is usually significantly more dynamic in application than CD or SACD.

So, I went onto the dr. loudness-wars website to see what the actual numbers are for that album. If you look at the database, the CD can be as bad as you say, but the SACD is no where near 40DB dynamic range, more like a quarter of that.

It actually has worse measured dynamic range than the myriad of vinyl rips on the database.

People assume that because digital has a THEORETICAL higher dynamic range than vinyl, that it actually matters in real world application. The truth of the matter is, that often times, especially with albums recorded in the days of vinyl prevalence, vinyl has the upper hand in dynamic presentation because of the mastering.

That's what I'm getting at, we're talking about different aspects of dynamics. In regards to DSOTM on sacd, it starts out at something like 70 DB and I could crank the volume to 110 dB before hearing distortion, in fact I never reached the distortion point. With cd the recording distorts at 98 dB.

So with the medium I am talking about how loud it can play before distortion. So vinyl's loudness limit would be under 98 dB.

Doesn't mean that vinyl won't exhibit better dynamics/contrast, within its dynamic range.

I am completely lost.

I didn't think that dynamic range had anything to do with distortion, nor did I think that distortion could be accurately measured by cranking up one's system.

I would assume, at 110DBs, that one's speakers and electronics would have more influence over distortion than the source medium.

I was thinking dBv off line-level and your using DB sound levels at 1m.  They are both good. Dynamic range is important at getting the natural instrument excitement that lies within an acoustic instrument recorded. Like the crash of a cymbal and natural decays. You referred to recording techniques that require dynamic range to develop the song like on DSOTM.  Both can be measured at the out-put of an amp and expressed in dbw (watts)
