+Features:
+* 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
+
+Limitations:
+* 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
