What triggers brake/flange squeal on my TMCC E-33 or railsounds Berk Jr tender?
Could a sound frequency be a trigger with the aid of filtering so every sound doesn't trigger it. (I know it could, I'm curious if a Chinese board might exist already. Like the old music detection "dancing" mood lights, with colored lights triggered by various frequencies and volume level changes varying color& intensity.)
