My own web-based multichannel peakmeter visualization already support automatic scaling of number of peakmeter bars (based on source audio's number of channels) and so should foo_audio_wizard get its per-channel true peak bars? However, this per-channel basis should also apply to sample peaks and RMS for consistency to allow them to automatically scale as well according to number of channels you have during playback, especially on surround sources
And what about adding a graph over time into the realtime monitoring window? Like this one below:

and Crossover's Loudness Peakmeter (foo_loudness_peakmeter) component and FabFilter Pro-L2 VST plugin
