We developed an analog rigid sphere microphone array with 64 microphones arranged according to the Fliege sampling grid. The array is suited for spherical harmonics processing and allows resolving spatial resolutions up to an order of N = 7. Incorporating a rapid prototyping approach most parts of the array are 3D printable and script-based modification allows for an easy adaption to other sampling grids and radii. All the parts of the project are freely available under the GNU v3 license.
