puredata-extra - 0.51.4-1+deb11u1 main

Pure Data (also known as Pd) is a real-time graphical programming environment
for audio and graphics processing.
.
This package provides extra objects that come with Pd, e.g. for signal
analysis (fiddle~, sigmund~, bonk~) and more.
.
The objects for expression evaluation (expr~) have been included into
puredata-core, so they are no longer part of this package.
