Audacity Forum

thank you. The internal mic was selected and not inline. When I switched it there was no high pitched sound. In the morning I will try to record again. Thank you very much for your help.

My mac is a power PC G4 and runs on operating system 10.4.11. I have been using audacity 1.2. The high pitched sound is there without any input device plugged in. I have downloaded 1.3 but when try open it I get message that 1.3 will not work with my operating system.

I have used audacity for quit awhile and it has worked fine till the other day. When I press the record button a very high pitched sound starts and the recording level bars go to max. Does anyone have any ideas why?
