LV2 plugin for broadband noise reduction


  • Spectral gating and spectral subtraction suppression rule
  • Adaptive and manual noise thresholds estimation
  • Adjustable noise floor
  • Adjustable offset of thresholds to perform over-subtraction
  • Time smoothing and a masking estimation to reduce artifacts
  • Basic onset detector to avoid transients suppression
  • Whitening of the noise floor to mask artifacts and to recover higher frequencies
  • Option to listen to the residual signal
  • Soft bypass
  • Noise profile saved with the session


  • The plug-in will introduce latency so it’s not appropriate to be used while recording 23 ms for 44.1 kHz
  • It was developed to be used with Ardour however it is known to work with other hosts
