Me too.

I have 2 computers - 1 desktop and 1 laptop - with the same symptoms.

I sent the help folks a test file from which I created 2 audio files. 1 audio file was rendered from the test file and it sounds fine. Then I recorded the test file again with a Zoom Recorder set up within my room. The zoom file has the distortion.

BTW, my 32 bit version works fine. My 64 bit version is where the problem is.
