We start this test by measuring the dynamic. Dynamic represents the ability to reproduce a wide range of sounds from the softest to the loudest.
For our 5 editions we have obtained the following Dynamic Range (DR):
|Ed1 Vinyl||Ed2 CD||Ed3 Digital File Binaural||Ed4 Digital File 5.1||Ed5 Streaming|
The DR vary globally from 9 to 10 for all digital release except for the streaming (DR12) and the vinyl (DR13). The dynamique is globally good for digital( CD and download) and very good for the vinyl and Streaming. The result is special for the Ed4 because it’s the result of the reduction of channels from 5.1 to 2.0. When listening, the result is more dynamic due to the distinction between the 5 channels of music.
As a reminder, the scale goes from 0 to more 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.
