VU meter for stereo data with L/R peaks

Hi. Firstly, this is a handy tool you have built here. If I am using stereo data I2S_CHANNEL_FMT_RIGHT_LEFT' and use your code to split into bands for a VU meter like your FastLED.ino example, then do you see any issues?

In addition to this, I would also like to get peaks for left and right channels. Is there a way to do this?

Thanks!
