Denoising Methods Explained

  • FFT Denoiser: General-purpose noise reduction using spectral subtraction. Good for constant background noise like fan hum, air conditioning, or electrical buzz. Adjust the noise floor to control how aggressively noise is suppressed.
  • Non-local Means: Advanced denoiser that works especially well for speech recordings. It preserves voice quality while reducing ambient noise.
  • High-pass filter: Removes low-frequency rumble and hum (e.g., from motors, wind, or electrical interference). Set the cutoff frequency to control which low sounds are removed.
  • Low-pass filter: Removes high-frequency hiss and sibilance. Useful for tape hiss, electronic noise, or overly bright recordings.

Tip: Start with moderate settings and increase gradually. Aggressive noise removal can affect audio quality. For best results with the FFT denoiser, try -30 dB first, then adjust based on the output.
