Thanks again, I don't know anything about Python programming but where would I label the inputs for the frequency and the volume at? I can easily make the changes to the frequency, a dog whistle is anywhere from 16000 to 22000 Hz and for the volume anything over 0.1 is to loud the speakers on the FreeRunner struggle with it, what I mean by that is 22000 Hz sounds lower than 17000 Hz.
