Dynamic Range Meter

A couple of months ago I’ve found a very interesting website which fights against the loudness war; Dynamic Range Database.

dr-meter-windowsThe Dynamic Range Database uses a sliding scale from 1 to 20 (1 being the worst, 20 being the best) to rank the dynamic quality of each of the recordings they list. This number represents the difference between the peak decibel level on a recording and the recording’s average loudness.

Dynamic Range Database applies the following descriptors to these ranges:
1-7=bad; 8-13=transition; and 14-20=good.

Evaluation for each album on the website includes the album’s average dynamic range, the track with the weakest dynamic range, and the track with the greatest. The Dynamic Range Database also provides individual dynamic range measurements for each track on the album. Below on this page you find three free downloads to test your own collection of CDs, DVDs, LPs or your music files. You can also share and add your results to the Dynamic Range Database by simply fill in the form and upload your data.

Below an example taken from an “Eagles – Hotel California” CD.
