About the Software Examples</A>
|

</H1>

|
|
<P>
|
|
The examples for this book use Pure Data (Pd), and to
|
|
understand them you will have to learn at least something about Pd itself.
|
|
Pd is an environment for quickly realizing computer music applications,
|
|
primarily intended for live music performances. Pd can
|
|
be used for other media as well, but we won't go into that here.
|
|
|
|
<P>
|
|
Several other patchable audio DSP environments exist besides Pd. The most
|
|
widely used one is certainly Barry Vercoe's Csound [<A
|
|
HREF="node202.html#r-boulanger00">Bou00</A>], which
|
|
differs from Pd in being text-based (not GUI-based). This is an advantage in
|
|
some respects and a disadvantage in others. Csound is better adapted than Pd
|
|
for batch processing and it handles polyphony much better than Pd does. On the
|
|
other hand, Pd has a better developed real-time control structure than Csound.
|
|
Genealogically, Csound belongs to the so-called Music N languages
|
|
[<A
|
|
HREF="node202.html#r-mathews69">Mat69</A>, pp.115-172].
|
|
|
|
<P>
|
|
Another open-source alternative in wide use is James McCartney's SuperCollider,
|
|
which is also more text oriented than Pd, but like Pd is explicitly designed
|
|
for real-time use. SuperCollider has powerful linguistic constructs which make
|
|
it a more suitable tool than Csound for tasks like writing loops or maintaining
|
|
complex data structures.
|
|
|
|
<P>
|
|
Finally, Pd has a widely-used sibling, Cycling74's commercial program
|
|
Max/MSP (the others named here are all open source). Both beginners and
|
|
system managers running multi-user, multi-purpose computer labs will find
|
|
Max/MSP better supported and documented than Pd. It's possible to take
|
|
knowledge of Pd and apply it in Max/MSP and vice versa, and even to port
|
|
patches from one to the other, but the two aren't truly compatible.
