 .SH DESCRIPTION
-sfizz_render wraps the sfizz SFZ library and can be used to render midi file as sound files using an SFZ description file and its associated samples.
+sfizz_render uses the sfizz SFZ library to render a MIDI file into a sound file using an SFZ description file and its associated samples.
