About Fan & AC Noise
Fan and AC noise is probably the number one complaint from people recording at home, in an office, or on a laptop. These sources put out a mix of hum and whooshing that sits under everything. This tool learns the unique sound profile of that mechanical noise and strips it out while leaving your voice alone.
Tips for Better Results
- Turn off fans and AC during recording when you can, even for short sessions.
- Put your mic as far from the noise source as you can manage.
- Use a noise gate in your recording software to mute the mic during pauses. It cuts down on perceived noise.
- A USB mic with a cardioid pattern rejects more off-axis noise than an omnidirectional one.
