What I do in those two apps is that when I turn "off" recording, I change the wavfile filename to /dev/null, which causes a formal cleanup-and-close of the previous file.

Use a conditional _expression_ in the "filename" field of the wavefile sink, and then have a "checkbox" control to control recording.  Make the _expression_ conditional on the state of the checkbox, and if "recording" isn't checked, make the file /dev/null, otherwise make it the file you want.
