I'm using the free version to listen to an Amazon Echo Dot with processing added through a set of speakers.
However when I turn audio off on my Echo Dot, StereoTool starts making a quiet helicopter noise for some reason, sounds like a bassy helicopter. I assume it's one of the features in StereoTool playing nasty with my cheap USB sound card. It's weird because depending on what preset I choose, the speed of the helicopter noise changes. I think some presets make it go away altogether.
Does anyone know what could be causing this helicopter sound, and how to get rid of it?
