I believe so, I'm running this code: https://github.com/libpd/libpd/blob/master/samples/cppTest/src/main.cpp and I presume line 56 (pd.computeAudio(true);) switches on DSP...

Thanks Josh

Hi all

Apologise for the novice question, but I'm trying to work purely with C++ & libpd (OSX desktop) and have been working with samples/cppTest/cpptest.xcodeproj from https://github.com/libpd/libpd.

I can build the project fine (libpd & the cppTest app) but when it opens the test patch (or any for that matter) I do not get any sound. The patch themselves works fine. Print statements are ok and sending & receiving messages seem ok. But I even built a patch which just *~ two phasors, and couldn't hear it when I used the cppTest code to open my patch. I don't think there is anything wrong with libpd nor my sound card as I compiled & ran the iOSTest project (deployed to a simulator iPhone) and that worked (fuzzy audio, but sound came through).

Anyone have any good ideas? I know that with the output AudioUnit on OSX has a default volume of 0 (unlike iOS which has default of 1.0 for volume) so would it be something like that?

Thanks!!! Josh

Did you send a "dsp on" message to your patch?

And yes, the iOS Test project does the audio I/O for you.

Maybe I'm missing something when skimming through your code, but, where are you setting up audio I/O? libpd doesn't do that automatically for you. Here's my implementation https://github.com/rvega/XookyNabox/blob/master/src/main.cpp It uses jack as audio I/O and libpd as DSP processing.

Check out RTAudio or PortAudio. I've had better results with RTAudio.

Hi Rafael

Many thanks for your feedback! I'm glad there's actually something missing rather than the code just not working.

My other question is then, if I don't want to use Jack and just want to use something simple to tie up the dac of libpd to my default sound card - is there a simple way of doing that?

Thanks Josh
