I also would appreciate this functionality.
Although I do use the "boosts volume" option on one podcast, it "overshoots" the others now by a small (but annoying) margin.
As a proposed code/library you might want to look into FFmpeg's implementation of their solution: https://trac.ffmpeg.org/wiki/AudioVolume and http://ffmpeg.org/ffmpeg-filters.html#loudnorm which is based on the EBU R128 broadcasting recommendation (https://tech.ebu.ch/docs/r/r128.pdf)
As a bonus, ffmpeg can be compiled as LGPL compliant (2.1) (http://ffmpeg.org/legal.html) and if dynamically linked (not embedded) should pose no problem.Dekker supported this idea ·
