High pitch squeal under acceleration

If I step on the gas I get a high pitched whistle, like a TING!........It doesn't always occur under the same RPM, and appears influenced by a rapid increase in acceleration.

I'm mostly certain I've heard the same in drive, and this has been going on a long while, despite lubing the belts and pulleys. It's just more obvious in park. Other than that, the engine sounds good. If necessary, I could create a video.

Thank you.
