Dynamic

Dynamic represents the ability to reproduce a wide range of sounds from the softest to the loudest.

More the dynamic is high, more the natural side of the recording is respected. For psycho-acoustic reasons, record companies tend to compress the sound, i.e. to reduce the gap between the weakest and the strongest sound to give an impression of power to listening. 

Measuring the dynamics of a measurement, is a complex process, which can be done in different ways but generally on a logarithmic scale. The ITU has standardized the way to measure the dynamic of a recording but here we will use another technique based on the TT Meter software from the Algorithmix company which is widely used by the community to create comparative databases of different albums.

For our 2 editions we have obtained the following Dynamic Range (DR):

	Ed1 (Vinyl)	Ed2 (CD)	Ed2 (Streaming)
Global	DR12	DR10	DR12
Min	DR10	DR8	DR11
Max	DR14	DR12	DR14
The A Team	DR12	DR11	DR11
Drunk	DR11	DR9	DR11
U. N. I.	DR12	DR10	DR12
Grade 8	DR13	DR10	DR12
Wake Me Up	DR14	DR13	DR14
Small Bump	DR10	DR8	DR11
This	DR11	DR10	DR11
The City	DR12	DR9	DR11
Lego House	DR12	DR8	DR11
You Need Me, I Don’t Need You	DR12	DR9	DR11
Kiss Me	DR13	DR10	DR12
Give Me Love	DR11	DR8	DR13
Autumn Leaves*		DR10
Little Bird*		DR9
Gold Rush*		DR12
Sunburn*		DR11

The DR vary globally from 10 to 12, which is a good dynamic for the vinyl release and Streaming release. There are even tracks above DR14.

As a reminder, the scale goes from 0 to just over 20, but the dynamics are considered good from 12, quite good between 10 and 11, and deteriorate below 10.
A low DR deviation (1 or 2) may be due to compression or a different treble level. Indeed, an increase in trebles has the effect of accentuating the perception of dynamics during listening but also during measuring.
The CD release have a lower DR10 which will be seen on the signal representation of both editions.
