FAQ
What types of noise can be removed?
Effective at removing steady-state noises like constant background hum, electrical interference, and fan or air conditioner buzzing. Less effective on sudden sounds like voices or music.
How should I choose the intensity?
Use "Medium" for most cases; choose "Strong" if noise is heavy, but avoid excessive strength as it may make vocals sound muffled — compare results to decide.
Why is it slow sometimes?
Denoising involves frequency-domain processing, which requires more computing power than simple format conversion. Be patient with long audio files; consider trimming to just needed segments first.
