For consistent tones interfering with your files, i cant stress enough the magic of editing the frequency spectrum of an audio file. IT IS A FEATURE MANY STP USERS ARE NOT AWARE OF. It is easy to do:
... in the audio file editor window, select the upper right tool in the window to show the frequency spectrum display instead of the wave form.
Right click the left grey area of the window outside the audio file (where the frequency graph is) and select"logarithmic" view - then right click on the file itself and select "show spectrum controls" - use the minimum and maximum frequency controls to highlight your buzz - which will be visibly obvious.
then select the frequency select tool - right next to the arrow in the upper left window of the file editor (
NOT at the top of the session, which contains a different set of similar tools) - once you click on the frequency select tool, you will get a cross hair tool in the audio window. If you use that to narrow in on the visual line of the buzz, highlight it, and then delete those frequencies - you will be amazed at how clean it will sound. Its magic!
