Works really well for playing DVDs, which have the volume turned way down for some reason. The `2' method is better IMHO because it will adjust to changing loud/soft parts. If you want to add it to your ~/.mplayer/config: # format: volnorm[=method:target] # method: # 1: use single sample (default) # 2: multiple samples # target: # default is 0.25 af-add=volnorm=2:0.75

This normalizes volume in your mp3 library, but uses mp3gain's "album" mode. This applies a gain change to all files from each directory (which are presumed to be from the same album) - so their volume relative to one another is changed, while the average album volume is normalized. This is done because if one track from an album is quieter or louder than the others, it was probably meant to be that way.

You need to be root to do this. So check the command before running it. You enter the same password for Enter LUKS passphrase: Verify passphrase: Enter passphrase for /dev/loopn: ___ You can then copy the .img file to somewhere else. Loop it it with losetup -f IMAGENAME.img and then mount it with a file manager (eg nemo) or run mount /dev/loopn /media/mountfolder Acts similar to a mounted flash drive Show Sample Output

If you have more than one SINK

This command sets the volume for the main PulseAudio "sink" (usually the ALSA output interface) to the maximum, 100% (the 0x10000 in the command). To set it to an arbitrary volume, replace 10000 with the volume you want times 100 (so 75% becomes 7500).

adjusts the 'Master' channel's volume up by 1dB. Can use command 'amixer' to see other channels : Simple mixer control 'Master',0 or Simple mixer control 'Capture',0 Show Sample Output

to run write: Sound-volume 30% or Sound-volume 1% Sound-volume 100% Show Sample Output

Command to raise the volume. From https://wiki.archlinux.org/index.php/PulseAudio#Keyboard_volume_control

This is an easy way to quickly get a status for a device in multipath on SLES systems, as long as the server is configured based on Novell's standards, where multipathed disks are referred to by /dev/disk/by-... tree. Make sure to replace name_of_vg with your Volume Group name.

Execute this in the root of your music library and this recurses through the directories and normalizes each folder containing mp3s as a batch. This assumes those folders hold an album each. The command "normalize-audio" may go by "normalize" on some systems.
