Article: Dynamic Range: No Quiet = No Loud

[freddie40]

After reading your article on DR analysis I wanted to see what my collection looked like.  I set up a field in JRiver to show DR results and went about testing about 4200 CDs.  What I did different was to break down the difference between Redbook, Hi-Res PCM and Hi-Res DSD.  I have also analyzed just the releases I have from Blue Coast Records.  Here are my results:

 

RedBook  1982 CDs

 

1-7  227   (11.45%)

8-10  780   (39.35%)

 

Thus 0-10 (BAD)  1007  (50.76%)

 

11-13   782   (39.46%)

14-18   194   (9.79%)

 

Thus 11-18 (Good)  976  (49.24%)

 

 

 

 

Hi-Res  2200 CDs

 

1-7  86   (3.91%)

8-10  592  (26.91%)

 

Thus 0-10 (BAD)  678  (30.82%)

 

11-13   1142   (51.915%)

14-18   382   (17.36%)

 

Thus 11-18 (Good)  1524  (69.27%)

Hi-Res  PCM  1313 CDs

 

1-7  79   (6.02%)

8-10  407  (31%)

 

Thus 0-10 (BAD)  486 (37.01%)

 

11-13   668   (50.88%)

14-18   160   (12.19%)

 

Thus 11-18 (Good)  828  (63.06%)

 

 

 

Hi-Res  DSD  887 CDs

 

1-7  7   (0.79%)

8-10  185  (20.86%)

 

Thus 0-10 (BAD)  192  (21.65%)

 

11-13  474   (53.44%)

14-18   222   (25.03%)

 

Thus 11-18 (Good)  696  (78.47%)

Looking at Just DSD releases from Blue Coast Records:

 

Hi-Res  Blue Coast DSD  68 CDs

 

1-7  0   (0%)

8-10  0  (0%)

 

Thus 0-10 (BAD)  0  (0%)

 

11-13  26   (38.24%)

14-18   42   (61.76%)

 

Thus 11-18 (Good)  68  (100%)

Your effort is admirable.

What is a "hi-res CD"?

Redbook is 16/44.  Hi-Res is anything that is 24 Bit, i.e. 24/96 or 24/192.

@freddie40 Very interesting. How many of those are non-classical? I did something similar in JRiver. Made a playlist with everything I have that is classified as rock, blues, alt, etc., but contains no classical or jazz type recordings. Sorted by DR with a total of 16,564 titles. DR11 or less = 13,106. About 20% of my collection is DR12 or greater.

 

I have no classical or Country.  They are all Rock, Jazz or Blues.

 

BTW:  The DR values of the Albums in my collection are an average of the DR of the songs of each album.  Not necessarily easy to do in JRiver.

If you looked at 1-10 and 11-20 I bet you results would be much closer to mine.

Hi Dave, I sorted on DR10 or less = 11,390 titles, which is a about 70% of my collection. Cheers, Mitch

 

Part of the difference is the type of music that we own.  Some music is recorded much better than others.  It just depends.

I've been on a re-buying tear this past year replacing my bad/poor DR music with good DR. I check out what I own w/the DR meter and if its bad go to the DR site and find a good issue, comb Discogs, eBay, SH forum and buy it. I think I've bought about 100 CD's this year not to mention SACD's. The difference in sound is significant and I'm quite happy I've reviewed my older music. All the new stuff I immediately check DR.
