I'm having a terrible problem with Camtasia. I'm using a Presonus FireStudio Tube, FireWire connection on a Mac with Mojave. My microphone is AKG C3000B. When I record a screen capture with audio I'm getting TOO MUCH noise. I'm recording some tutorials, so its important to record both voice and system audio, but its impossible to use the voice I record on Camtasia during the screen capture, and I had to do the voices again at Reaper or other DAW. Theres no problems while recording at Reaper or Logic, only in Camtasia. Can anyone help me?
