I used Foobar2000 for long time as best replaygain scanning solution. Still have it installed, more as audio toolkit than player now. There is command-line mp3gain package, but I believe this has been dropped from Debian and Ubuntu repositories. I was able to compile older version of mp3gain from Ubuntu 14.04 for Ubuntu Studio 16.04 no problem. Not necessary now as Martin Wimpress created an Ubuntu repository for mp3gain and aacgain <https://launchpad.net/~flexiondotorg/+archive/ubuntu/audio> I use QtGain <https://sourceforge.net/projects/qtgain/> as GUI front-end, easy to drag a folder or file in to scan. I also added a custom right click option in Thunar file manager. With or without GUI, the scan is slightly faster than Foobar (on my pc) and I can't hear any difference in sound levels in final playback -- View this message in context: http://linux-audio.4202.n7.nabble.com/Playing-mp3-from-playlist-with-equal-volume-tp102265p102500.html Sent from the linux-audio-user mailing list archive at Nabble.com. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
