+     "This package provides a C library for audio noise reduction and other
+spectral effects.  It is based on the algorithms that were used in
+@code{noise-repellent}.  These were extracted into a this standalone library to
+remove the lv2 dependency.  It uses the concept of a spectral processor which
+itself uses a @acronym{STFT, short time Fourier transform} to process the audio.")
