I’m pleased to share my new Max externals. It includes the beta of pg.descriptor~ the fft friend of waveform~ (Sonogram and analysis of a buffer~) and other fft, dsp and max externals :

I hope that you’ll enjoy it and be pleased to have feedback.

thanks for sharing !

but your FFT externals do not work here : (Max 6.0.5 / macOs 10.7.4)

(same error message for all FFT objects)

looks like libfftw3.3.dylib is not included in the object…

Yep, I don’t explain how to use the fftw3… I should add few line about it!
The .dylib are dynamic library, externals can be compiled with a static or a dynamic library. With a dynamic library the user need to have it on his computer. With a static library, the library is in the package but I’m not sure that it’s going to work everywhere. I’m a developer since less than a year and I’ve never try to use static library before. Here, I’ve try with the pg.energy~, can you tell me if it works? If it’s works I’m going to make two library for max (a static one and a dynamic one) and publish it otherwise you’ll have to wait until I really understand how to do and try it on several computer.

The other solution is to install the fftw3 on you Mac. There’s several links where you can install the fftw3 library, it’s really easy and fast and it could be useful because this library is very popular :

http://pdb.finkproject.org/pdb/package.php/fftw3?rel_id=10.7-x86_64-current-stable

http://antst.net/Site/FFTW_for_MAC_OS_X.html

I think it’s should work.

Feedback helps me to improve my library, if you have other comments, I’ll be pleased to know it.
Thanks a lot.

Pierre

with [pg.energy~] i get :

2012-06-14 11:42:03.432 MaxMSP[214] CFLog (21): dyld returns 2 when trying to load /Users/jeantoto/Download/pg.energy~.mxo/Contents/MacOS/pg.energy~

max 5.1.9 / OS X.4.11.

As expected, my static library don’t work with all the OS X version. I’m going to solve this problem in the next few days. And you use Max 5.1.9, have you try with Max 6 runtime? I said yesterday that there’s differences between the MaxAPI of Max 6 and MaxAPI of Max 5, that’s why the FFT externals work only on Max 6 :

I’m going to compile everything with the Max 5 SDK today. I’ll post a message when it will be done.

Thanks

i did not try max6 as it is announced to require 10.5 and later only.

For Mac the FFT externals should work now for Max 5 and Max 6, but you still need to install the fftw3. I going to do the same for Windows now… or perhaps tonight… or tomorrow.

Thanks

Now I should work on Windows and OsX on MAx 5 and Max 6 and I give a few words of explanation about the fftw3. If you find something else that could be improved, please tell me.

Thanks.
