 Good evening

 '''Thank you very much for sharing your great work!,''' I use ffmpeg to
 optimize free lectures and it's great.

 Question:
 '''Could you please think about enabling ffmpeg to calculate a more
 detailed DB histogram?
 '''
 As an example, ''volumedetect'' automatically selects the histogram ranges
 and generates this result:

 {{{
 [Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_4db: 8
 [Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_7db: 3369
 [Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_9db: 49398
 }}}

 I often would like to examine a dB range more closely, so it would be
 brilliant if ''volumedetect'' could calculate more values.

 These solutions come to my mind:

 1. One can explicitly specify which dB ranges should be analyzed, e.g.
 ''"volumedetect:7;7.5;8dB"''

 2. One can specify which dB range should be analyzed, e.g.
 ''"volumedetect:7-8dB"''

 3. One can specify the number of calculated DB values, ''volumedetect''
 then selects the ranges itself. e.g. ''"volumedetect:12"'' will calculate
 12 histogram ranges.


 I would prefer No. 1. because this is most flexible.

 Thanks a lot for your review,
 kind regards,
 Thomas
