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