Two new (basic) ambisonic externals for Pd. They will form a large part of the new grambilib~ library I am finishing this semester, allowing a user to control angle and elevation using an audio-rate signal. They're largely based on the rg.ambi~ abstractions from 2015. All objects are written in the C programming language. Both externals collectively allow a user to use 1st (3d), 2nd (2d), and 3rd (2d) order ambisonics for mono, stereo, quad, 5.0, hexagonal, octagonal, and b-format cube (3d) array configurations.

Drop me an email: info@rickygraham.net

Maybe we can collaborate on the project.

I just did that, thanks Ricky!

@ricky this looks awesome!

I'm getting this error when loading: fat file, but missing compatible architecture (have 'i386,x86_64', need 'arm64)

Is there a version that runs on Apple Silicon?

@bklindgren you could try to compile it yourself. It's on GitHub https://github.com/rickygraham/grambilib/tree/master
There's Makefile, but I guess you could use Pd's pd-lib-builder https://github.com/pure-data/pd-lib-builder

@alexandros

thanks for the suggestion! I"ve never compiled anything before, but I gave it a shot...

I'm getting this error in PD after loading the 3 compiled objects (6 files: grambidec.pd_darwin, grambidec.pd_darwin.o, grambiman.pd_darwin, grambiman.pd_darwin.o, grambipan.pd_darwin, grambipan.pd_darwin.o):

 load_object: Symbol "grambiman_setup" not found in "/Users/brianlindgren/Documents/Pd/externals/grambiman.pd_darwin"

Also make is generating a bunch of warnings:

This is my Makefile:

# Makefile for mylib

lib.name = grambidec~

class.sources = grambidec.c grambiman.c grambipan.c

datafiles = grambilib-help.pd readme.md

include Makefile.pdlibbuilder

Any suggestion? Thanks again!

I'll check when I have time and get back. Should be simple.

@bklindgren I copied your makefile and compiled with the sources I have (I guess they are the same, since in GitHub they haven't changed in eight years), and [grambiman~] loads fine. I realized though the a [grambiman] compiles as well (no tilde), which indeed can't load. Did you forget to add the tilde character when you loaded the object?
I then changed the names of the source files, by adding the tilde character, and re-compiled. This time, only tilde objects were made. Maybe a bug of the makefile. I'll send to the Pd list or open an issue on GitHub.

thanks for your help! I got the objects compiled and loaded. it's been about two weeks so I'm a little fuzzy on what might have gone wrong before, but I modified a few file names & this is the makefile I ended up with:

# Makefile for mylib

lib.name = grambi~

class.sources = grambidec~.c grambiman~.c grambipan~.c

datafiles = grambilib-help.pd readme.md

include Makefile.pdlibbuilder

thanks again~ !!

Sorry. Totally missed this. All good?
