	rdfs:comment """balance.lv2 facilitates adjusting stereo-microphone recordings (X-Y, A-B, ORTF). But it also generally useful as 'Input Channel Conditioner'.
	It allows for attenuating the signal on one of the channels as well as delaying the signals (move away from the microphone). To round off the feature-set channels can be swapped or the signal can be downmixed to mono after the delay.
	It features a Phase-Correlation meter as well as peak programme meters according to IEC 60268-18 (5ms integration, 20dB/1.5 sec fall-off) for input and output signals.
	The meters can be configure on the right side of the GUI, tilt it using the 'a' key.""" ;
