Thank you for that. I was asking more about resources for learning C\C++ languages themselves keeping in mind that "writing DSP externals for pd" is my end goal. Any suggestions?

I have recently finished reading "The Scientist and Engineer's Guide to Digital Signal Processing" and I managed to go through half of the Addison Wesley's "C++ Primer 4th Edition" (and I'll probably keep reading it), but I feel that it would be good to learn more in a context of what I am really interested in.

The exercises in the C++ Primer are very dry and the examples in The Scientist and Engineer's Guide are all in BASIC (I could probably try to rewrite them in C++ as an exercise). Could anybody show me the light and point me to some books, or online resources (tutorials, bits of code easy to comprehend by a beginner) that could help me achieving my goal?

ps I was just wondering if I should start from learning C and then go to C++ or just learn C++ and then learn bits of C along the way?

Thanks for reading this!! :)

For externals, you should mainly use C.

for externals you should of course use the language that you are most fluent in.

Pd is written in C, so C is the most natural choice from Pd's pov, but probably not yours.

you can write externals in a wide number of other languages as well (including (but not limited to) Pd (which is even more natural than C), C++, python, lua, java, haskell and HQ9+)

if you want to write C++ externals, you might want to use flext (which offers a nice framework and an awkward build-environment :-))

Hi IOhannes,

Could you expand a little on writing externals with python please?

Thanks, Lorenzo.

You can't really write externals in python, but you can embed python scripts into Pd using Thomas Grill's pyext. The Java support is a clone of Max/MSP's mxj, which is very similar to pyext. You can write external objects in Pd, C, C++, and lua.

.hc

Talking about interpreted languages you can also try to send and receive arguments through net sockets with [netsend] [netreceive] and you can use [shell] in linux for bash script or almost anything your linux shell can deal.

;;;

I am grateful for the tips. Just one question: is there any performance penalty for externals written using C++\flext comparing to pure C?

All the best.

Adrian
