The customization parameters are the array radius, the number and position of the microphones, their type and extra options such as the possibility to embed an USB sound card inside the array. The microphone arrays signal processing for a Spherical Harmonic decomposition is provided as a code in the Faust language. Also, Python codes are provided for the calibration of the Spherical Microphone Arrays using a robotic arm. + +# opensCAD designs +The designs are in the `cad` folder: +- `sma_open.scad` for open SMA configuration with cylindrical shaped microphones, +- `sma_rigid.scad` for rigid SMA configuration with cylindrical shaped microphones, +- `sma_rigid_mchstreamer.scad` for rigid SMA configuration with digital MEMS microphone and embedded USB sound card. + +Examples of SMA configurations are provide in `.json` files. +See the documentation in `.scad` files to customize a designs.
