The neologism "Pleasurize" sounds distinctly not credible to me. Sounds hokey.

Sounds hokey.Just supposition, but perhaps it's a poor translation, given that the group obviously originates in Germany.They seem very organised from looking at the site. I only hope they can make some headway!
Headway for headroom?
20 February 2009: Release version 1.1 of the TT Dynamic Range Meter and the TT DR Offline Meter is ready for release. German manual is already finished. Who can make a professional English translation (3300 words) very quickly? This should be done before making the software available. Please contact us via contact form. German manual will be uploaded now.

Where did you see the info referencing "3 seconds"? I couldn't find that sort of thing on their site.Depending on how they're computing their RMS numbers, and especially depending on equal loudness weighting and/or BS.1770 filtering, a full scale sine could very easily go way above 0db. pfpf does the same thing. It doesn't mean the meter should go negative; that doesn't make any sense.
Zur Ermittlung des offiziellen DR?Wertes wird der Titel bzw. das Image des Tonträgers (Wave, 16bit, 44,1 kHz) gescannt und im Hintergrund ein Histogramm (Lautheitsverteilungs? Diagramm) mit einer Auflösung in 0,01 dB?Schritten erzeugt. Die nach etablierten Standards für die RMS?Berechnung in einem Zeitfenster von 3 Sekunden ermittelten Lautheitswerte (dB/RMS) werden quasi in 10.000 unterschiedliche Schubladen aufgeteilt (der 0,01dB? Auflösung entsprechend). Von dem Ergebnis werden nun die lautesten 20% als Berechnungsgrundlage für die durchschnittliche Lautheit der lauten Passagen errechnet. Gleichzeitig wird der höchste Peakwert ermittelt. Der DR?Wert ist die Differenz zwischen Peak und Top?20 des durchschnittlichen RMS.
It's in the manual of the release version:http://www.dynamicrange.de/sites/default/f...1_1-Deutsch.pdf
So they calculate lots of RMS values over 3s windows, doing a histogram with a resolution of 0.01 dB, and finally they take the loudest 20% of those. However I don't understand what exactly they mean by 20% as I get slightly different values when I program it.
Funny you just write that Axon, that's just what I was doing:The Fall - The Classical [original] -- DR = 8The Fall - The Classical [-9.75 dB from original] -- DR = 9The Fall - The Classical [-30.00 dB from original] -- DR = 8
OK, I think I understood how the algorithm works:For every 3 seconds a RMS value is generated (so a 1h CD would have 1200 RMS values). Then the loudest 20% of those are averaged. The difference between this value and the peak is the DR value.I wonder why in the manual they talk about a histogram... because their algorithm doesn't need one?!
If that is true, then that's a very interesting way of measuring this. I would personally avoid doing it because it would be sensitive to clicks and pops (which would make it incompatible with vinyl), but it's a fairly good way of detecting over-loud CDs. I will read the English manual on Tuesday, when it's supposed to become available, to see whether you're right.
