Just for reference, this is not Audactity but what I did to get rid of the HISS or "White Noise" from CUBASE:
To all others, I got rid of the HISS (Crackling) by adjusting the buffer size and then doing the opposite of what the manual said and increased the CPU (the manuall said to decrease).
In CUBASE, DEVICES> DEVICE Setup > VST Mutitrack > Control Panel
Bit Depth to 24 and slid CPU UP until the HISS went away.
Tested and it works for both the MIC and the guitar.
Recording engineering discussions and questions. Also a great place to discuss software, plugins, and computer based recording/arranging.
