Motivation for this change

Project description
Alsaequal is a real-time adjustable equalizer plugin for ALSA. It can be adjusted using an ALSA compatible mixer, like alsamixergui or alsamixer.

Alsaequal uses the Eq CAPS LADSPA Plugin as it's default equalizer but you can change it to use almost any LADSPA plugin, like mbeq from the swh-plugin package. Though alsaequal is primarily intended to be used as an equalizer you should be able to use it to control any LADSPA plugin. It's similar in functionality to the LADSPA plugin provided with ALSA but allows for real-time controls as opposed to static controls defined in the asoundrc file.
