In Reply to: RE: But wouldn't the true dynamic range be the difference. . . posted by Chris from Lafayette on April 25, 2021 at 12:17:47
This site is a weapon in the Loudness Wars and they were/are all about increasing the average level so it is closer to the technical maximum of 0dBfs.
The minimum level remains -96dBfs as prescribed by the compact disc medium.
It is of no interest in the Loudness Wars, only the difference between average and maximum is.
Dynamic range, as it refers to an actual recording, should refer to the difference between the softest level and loudest level on that recording. Apart from this, the medium itself can have a maximum dynamic range - this is separate from the dynamic ranges of particular recordings played on that medium. I understand what the Loudness Wars were all about - although, as a classical listener, I've never had to worry about it. To say that DR is the difference between average level and maximum level is just a misuse of the term IMHO.
The EBU R128 definition of dynamic range is 95th percentile loudness minus 5th percentile loudness. It's trying to measure the difference between loudest and quietest passages by ignoring instantaneous peaks and moments of silence.
I think the R128 measure makes more sense for classical music. And the DR rating makes more sense for rock.
If you don't measure it from average to peak the dynamic range will always be around 96dB because the quietest passage is always silence and the loudest 0dBfs rendering the entire effort meaningless.
what the dynamic range of the music is on the recording. How could measuring the "average" tell you anything about the quietest sections of the music? Without measuring the quietest sections how could you get the real DR of the music on whatever medium you're listening to?
Nobody adjusts their volume so they can hear silence. You adjust volume so you can hear the quietest sections and the loudest sections aren't so loud that they blast you outta your listening room.
