+SpectMorph is a free software project which allows to analyze samples
+of musical instruments, and to combine them (morphing). It can be
+used to construct hybrid sounds, for instance a sound between a
+trumpet and a flute; or smooth transitions, for instance a sound that
+starts as a trumpet and then gradually changes to a flute.
+In its current version, SpectMorph ships with many ready-to-use
+instruments which can be combined using morphing.

+# 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 ':' except on otherwise blank lines.
