It works best on consistent, steady-state noise like electrical hum, fan noise, air conditioning, and tape hiss. It is less effective on intermittent sounds like coughing or traffic.
At moderate settings, voice quality is well preserved. Higher reduction levels may introduce slight artifacts, so always preview before downloading.
This tool targets background noise, not reverberation. Echo and reverb require different processing techniques and are not handled by this tool.
