Equalizer with no GUI for external controll
Clash Royale CLAN TAG#URR8PPP
I am programming a raspberry pi zeroW with usb audio card as bluetooth receiver with app controll. The app should controll an equalizer on the raspberry. Bluetooth audio and so is already running but I dont know how to do the equalizing part. I already experiment with pulseaudio-equalizer but I can't figure out how to controll it without gui. My idea was to set the parameters for the equalizer in an preset file which will be changed by the app.
I use raspdian stretch lite as OS und pulseaudio-module-bluetooth
linux debian raspberry-pi pulseaudio pulseaudio-equalizer

Pulseaudio-equalizer has a DBus interface (org.PulseAudio.Ext.Equalizing1.Equalizer), try using that like qpaeq does. If you consider JACK as well, jack-rack provides ALSA sequencer interface for any LADSPA effect plugin.

Pulseaudio-equalizer has a DBus interface (org.PulseAudio.Ext.Equalizing1.Equalizer), try using that like qpaeq does. If you consider JACK as well, jack-rack provides ALSA sequencer interface for any LADSPA effect plugin.
