Copyright 2023 Pierre Lecomte - sekisushai@gmail.com
The SMALL library provides an open-source set of Computer Aided Designs (CAD)s to easily
build Spherical Microphone Arrays (SMA)s prototype for research or home use. The
build Spherical Microphone Arrays (SMA)s (i.e. Ambisonics mics) for research or home use. The
designs are made with opensCAD, they are customizable and the different parts
can be directly 3D printed. Extra standard mechanical assembly elements may be
required such as screws or metal rods.

Examples of SMA configurations are provide in `.json` files.
See the documentation in `.scad` files to create or customize a SMA design.
# SMA signal processing
To encode the microphones signals onto Spherical Harmonics signals (i.e. Ambisonics signals), one can use ambitools.
See www.sekisushai.net/ambitools/docs/mic_encoder.html for more infos.
# SMA calibration with a robotic arm
If you build a prototype by using the SMALL library, let me know ;)
