Commands tagged volume (10)

  • 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

    mplayer -af volnorm=2:0.75 dvd://

  • 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.

    find . -type f -name '*.mp3' -execdir mp3gain -a '{}' +

  • 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

    edrv() { N=${1:-edrv}; truncate -s ${2:-256m} $N.img && L=$(losetup -f) && losetup $L $N.img && cryptsetup luksFormat --batch-mode $L && cryptsetup luksOpen $L $N && mkfs.vfat /dev/mapper/$N -n $N; cryptsetup luksClose $N; echo losetup -d $L to unmount; }

  • 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).

    pacmd set-sink-volume 0 0x10000

  • 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.

    pvscan | awk '/name_of_vg/ {print $2}' | sed 's/[-|/|]/ /g' | cut -d " " -f7

  • 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.


    -2
    find . -type d -exec sh -c "normalize-audio -b \"{}\"/*.mp3" \;

(Debian/Ubuntu) Discover what package a file belongs to
'dpkg -S' just matches the string you supply it, so just using 'ls' as an argument matches any file from any package that has 'ls' anywhere in the filename. So usually it's a good idea to use an absolute path. You can see in the second example that 12 thousand files that are known to dpkg match the bare string 'ls'.

A simple command to toggle mute with pulseaudio (any sink)
0 can also be replaced by the source name, e.g. alsa_output.pci-0000_00_1b.0.analog-stereo

Trigger a command each time a file is created in a directory (inotify)
Listens for events in the directory. Each created file is displayed on stdout. Then each fileline is read by the loop and a command is run. This can be used to force permissions in a directory, as an alternative for umask. More details: http://en.positon.org/post/A-solution-to-the-umask-problem%3A-inotify-to-force-permissions

Use md5sum to check your music and movie files. Also use diff.
This is a beginning script. You can create a file with > filename. You can also use diff to compare output run at different times to verify no change in your files. I apologize in advance if this is too simple. For some it should be a start.

Count Files in a Directory with Wildcards.
Remove the '-maxdepth 1' option if you want to count in directories as well

Clean your broken terminal
If something fracks up your terminal, just type in 'reset' and everything should be good again.

Get all IPs via ifconfig
and, a lot uglier, with sed: $ ifconfig | sed -n '/inet addr:/s/[^:]\+:\(\S\+\).*/\1/p' Edit: Wanted to be shorter than the perl version. Still think that the perl version is the best..
