Standard works best for most recordings. Aggressive for heavy noise; Subtle for light cleanup.

The tool uses spectral gating to remove consistent background noise: HVAC hiss, fan noise, room hum, computer fan noise, electrical hum (50/60 Hz), and microphone self-noise. It works best on steady-state noise rather than sudden sounds like claps or speech from another person.
At Standard strength, voice quality is well preserved. Aggressive mode removes more noise but may add a subtle artifact (sometimes described as a "watery" sound) to the voice. If you notice artifacts, try Standard or Subtle strength instead.

MP3 is best for sharing and uploading to podcast hosts. WAV or FLAC are best if you'll continue editing in a DAW. M4A is ideal for Apple devices and iTunes.
