I'm happy to announce balance.lv2. balance.lv2 is a LV2 audio-plugin for stereo balance control with optional per channel delay released in terms of the GPLv2. https://github.com/x42/balance.lv2 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 phase-inverted, swapped and the signal can be downmixed to mono. 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. balance.lv2 is *not* a panner. Even though the controls can be linked, the stereo signal paths are completely independent (except for the down-mix to mono output routing option). Many thanks to Chris 'oofus' Goddard who inspired the current signal flow, beta-tested the plugin and provided very valuable feedback. Greetings to Jörn Nettingsmeier who nagged me about not having a proper balance controller in Ardour and motivated this project in the first place. yours truly, robin
