Title: Improved audio analysis?? Please bring back intensity.
Post by: GreggP on February 14, 2014, 01:52:26 pm
I really appreciate all the new improvements with v19's audio analysis feature. However, I seem to have lost some functionality with these changes.

Before v19 forced me to re-analyze all my tracks with the new capabilities, I used the BPM an Intensity tags in smart playlists to generate a list of "mellow" songs. Something like:

BPM <= 75 and Intensity <=2

worked pretty well.

When Intensity disappeared, my smart playlists generated empty lists. So I had to come up with a different way to define "mellow". After a little research, I read a recommendation to use a high dynamic range, because that probably means the track has more quiet passages. However, that doesn't seem to work in this example. I seem to have quite a few loudish tracks with a high dynamic range.

Could you please bring back the Intensity analysis? Pretty please???

Thanks.

I posted this message/request a long time ago. By now, I figured it's been long forgotten... Bump???

I hadn't used this before, but it would certainly be nice to have.

Sorry, but intensity is gone for good.  Looking at the Dynamic Range is a good compromise.

First, welcome back!! It's great to see you posting again.

Can you give me a little more guidance on how to use dynamic range to identify mellow tracks?

I've tried tracks with large dynamic ranges, but they're not necessarily mellow. I wish there was a better way or combination of attributes that could be used that replace intensity. I used it for generating both relaxing playlists and party or workout type playlists. I suppose intensity might not have been really accurate, but if seems to have worked better than dynamic range does now. Just curious, what values were used to calculate the old intensity attribute/tag?

This Smartlist is a start:
[Volume Level (R128)]=<-10 [Dynamic Range (R128)]=>=10

is that volume level (R128) less than our equal to -10 or +10?

Less than or equal to -10.  You want songs without too much volume.

Minor correction:

   =< is less than
   =<= is less than or equal to

One more quick question (sorry): Why does volume level (128) have a negative value? Does a number greater than 0 mean it is pretty loud?

Yes.  The value is the change required to bring the track into the R128 volume level.  It's lower than most tracks, so it's a negative number of decibels.
