New feature request: Average Volume Level Detection

[trooperboy]

Hi,

I would like to put forward an idea for a new detection method.

In the UK allot of our TV channels have elevated volume levels during commercials breaks (it gets louder). On examining a .CSV file it is noticeable louder for the entire duration of the commercial break. During the breaks the average volume level is more than 100% louder than of programme.

Would this be possible to include such a detection method in a future release?

I REALLY should update the manual as its already available.
Please use the "punish" parameters
If you want to use only to punish on volume you may use these settings

punish=4 ; Compare to average for sum of 1=brightness, 2=uniform 4=volume, 8=silence, 16=schange, set to 0 to disable
punish_threshold=1.3 ; Multiply when amount is above average * punish_threshold
punish_modifier=2 ; When above average * threshold multiply score by this value

You can check with the debugwindow. The punished audio parts should have a red line, where the rest of the audio should have a white line
Make sure the segmentation (separation in blocks) is done correctly as punish only works on entire blocks.

Hi erik,

Thank you very much for this info, I had a feeling it might already exist.
An update to your manual would be nice, you have an entry for your comskip.ini that reads detect_method and volume is not one of those options. So as I saw it the feature did not exist.

Anyway thanks again for the info, I'll have a go at tuning the settings and see how I get on.
If I get this working with good results I may be tempted to make a donatation
