+vocoder (standalone JACK vocoder effect)
+
+A vocoder is a sound effect that can make a human voice sound
+synthetic. It is often used to speak like a robot, with a metallic and
+monotonous voice.
+
+This is a standalone JACK application. For a LADSPA version of the same
+effect, see vocoder-ladspa.
+
+This package uses POSIX filesystem capabilities to execute with
+elevated privileges (required for realtime audio processing). This
+may be considered a security/stability risk. Please read
+http://www.slackbuilds.org/caps/ for more information. To disable
+capabilities, pass SETCAP=no to the script.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
