Envelope question

I am a new user to Audacity, using it to convert vinyl records and cassettes to digital.

I have somehow turned on an “envelope” feature, which puts a white bar through my screen and takes away the vertical line I use to tell where I am in the recording. How did I turn this thing on and, more to the point, how do I get it to go away? It is of no use to me at all.

Thank you for any assistance.

The envelope tool is one of the tools in the Tools Toolbar.
