This software is a plugin for ALSA sound server that provides a real-time adjustable equalizer feature. It enables users to adjust sound settings according to their preferences.
Alsaequal is powered by the Eq CAPS LADSPA Plugin for audio processing. While it is technically a generic LADSPA plugin interface, it offers the rare feature of real-time access to the LADSPA controls. This sets it apart from the LADSPA plugin included in ALSA, which does not allow for the same level of control. It's worth noting that Alsaequal was specifically designed to work with the Eq CAPS LADSPA plugin, but users are welcome to experiment with other plugins to see if they are compatible.
Installing Alsaequal on your system is a breeze. Simply download the latest version of the plugin and follow these instructions: tar xvjf alsaequal-x.x.tar.bz2, cd alsaequal-x.x, make, then sudo make install.
After installation, you will need to modify your local .asoundrc alsa configuration file by adding the following lines (if you're not using sound card 0, adjust "plughw:0,0" accordingly): ctl.equal { type equal; }, pcm.plugequal { type equal; slave.pcm "plughw:0,0"; }, and pcm.equal{ type plug; slave.pcm plugequal; }.
Playing audio through Alsaequal is easy - simply address the plugin by name: e.g. mpg123 -a equal 06.Back_In_Black.mp3. To adjust the frequency response of the equalizer, use any ALSA mixer, like alsamixer -D equal.
Overall, Alsaequal is an excellent choice for users looking to fine-tune the audio settings on their ALSA sound server. It's user-friendly, highly adjustable, and compatible with a wide range of plugins.
