About Noise Reducer

The Noise Reducer tool helps clean up audio recordings by removing unwanted background noise, hiss, and hum. It combines multiple techniques:

  • Frequency Filtering: Reduces high-frequency hiss and low-frequency rumble.
  • Noise Gate: Automatically silences audio when it falls below the threshold.
  • Smoothing: Prevents choppy transitions when the noise gate activates.

Adjust the parameters to find the right balance between noise reduction and preserving audio quality. For best results, use headphones when adjusting settings.
