Hi William,

Are you aware of --> https://github.com/pure-data/pd-lib-builder

This will ease building on many platforms including the upcoming windows64bit.

You will like it.

Ok - I think I've got a decent version for testing built for Linux, Mac, and Windows. Clone here and try it out if you're interested:

Thanks Marco, I just tried it and it worked perfectly. I'll build for the other platforms at some point today at get those binaries and the updated source pushed to git for testing.

Peter - thanks for the suggestion too. At this point I've committed to [convolve~] being self-contained with all of its IR analysis stuff, so I think with this clock_delay() trick I'm all set.

hi william,

i met the same problem in [loadmess]. actually you can clock a 0-delay time; in this case the loading method should be evaluated at the end of the same logical time, providing that the loadbanged array is evaluated. if this solution is not correct, i have to change loadmess :)

best,
marco

That's something I actually did for this round and then abandoned. I had it taking an array name as the 2nd argument (so it wouldn't break backward compatibility), and then automatically running the IR analysis routine at the end of object creation. The problem I couldn't come up with a good solution for was that the IR array won't necessarily be loaded with samples before [convolve~] creates. So in a scenario where you have a patch that loadbangs an IR .wav file into an array as the patch starts up, [convolve~] tries to analyze the IR array given as a creation argument before the .wav is loaded, and ends up analyzing an array full of zeros.

I started on a strategy where I set a clock to wait a certain amount of time before running the analyze routine at the end of object creation, but that seemed like bad design. Anyone have any suggestions for this problem?

Awesome!

I always hoped convovle~ could take an optional symbol argument to define an array to analyze. Any chance of that?

cheers

Hi all,

I just got around to making some updates to [convolve~] for partitioned IR convolution reverb. I'm now using FFTW so that non-power-of-two window sizes are possible, which gives finer control over the delay between the dry and wet signal as well as CPU% impact. You can change window size on the fly now too. The other major difference is an FFT filter eq method for making custom adjustments to the IR's spectrum.

I'd appreciate testing from anyone who's willing. The source, help file, and Mac OS binary are here:

https://github.com/wbrent/convolve_tilde.git

I'll probably update with Windows and 64bit Linux binaries tomorrow. Or, the Makefile will let you build in the meantime if you build/install FFTW first.

William
