Ed Sheeran – + (Vinyl, CD, Streaming)

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)
GlobalDR12DR10DR12
MinDR10DR8DR11
MaxDR14DR12DR14
The A TeamDR12DR11DR11

You Need Me, I Don’t Need YouDR12DR9DR11
Kiss MeDR13DR10DR12
Give Me LoveDR11DR8DR13
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.
