Alsaequal is an equalizer for the ALSA soundsystem that can be used from command line. It gives system-wide equalizer capability to your Debian system.

'''Tested on Debian 7.4 Wheezy 4/4/2014'''

This guide requires you have MPD installed and working with alsa

==Download Alsaequal==
Download File: [http://www.etcwiki.org/dl/alsaequal-0.6.tar.bz2 alsaequal-0.6.tar.bz2]

==Make and Install alsaequal==
*Get Dependencies
aptitude install build-essential caps libasound2-dev libasound2-plugins
*Switch to home directory and download alsaequal
wget http://www.thedigitalmachine.net/tools/alsaequal-0.6.tar.bz2
*Extract alsaequal, enter directory
tar xf alsaequal-0.6.tar.bz2
cd alsaequal
*Make soft link to alsa-lib for alsaequal make process
ln -sf /usr/lib/i386-linux-gnu/alsa-lib /usr/lib/alsa-lib
*Run the make processes
make clean
make
make install
make clean
*alsaequal is now installed if you had no errors

==Apply alsaequal at boot==
*edit your ~/.asoundrc (make it if it doesnt exist)
nano ~/.asoundrc
*Add these lines
ctl.equal {
type equal;
}
pcm.plugequal {
type equal;
# Modify the line below if you don't
# want to use sound card 0.
slave.pcm "plug:dmix";
}
# pcm.equal {
# Or if you want the equalizer to be your
# default soundcard uncomment the following
# line and comment the above line.
pcm.!default {
type plug;
slave.pcm plugequal;
}

==Link MPD with alsaequal==
*for this you just need to modify your primary alsa device in /etc/mpd.conf to be like so:
audio_output {
type "alsa"
name "My ALSA EQ"
device "plug:plugequal"
mixer_type "software" # optional
mixer_device "default" # optional
mixer_control "PCM" # optional
mixer_index "0" # optional
use_mmap "yes"
}

==Restart and check alsaequal==
*Alsaequal should now be installed and working, try running it
alsa force-reload
service mpd restart
alsamixer -D equal
*If you are using root user change user in mpd.conf to root

==Troubleshooting==
#A bad idea so says everyone basically, but in /etc/mpd.conf I had to change user to root for this to work. It is probably because I log in a root more than I should...
