Abstract: Spherical microphones arrays are commonly utilized for recording, analyzing and reproducing sound-fields. In the context of higher-order Ambisonics, the spatial resolution depends on the number and distribution of sensors over the surface of a sphere. Commercially available arrays have set configurations that cannot be changed, which limits their usability for experimental and educational spatial audio applications. Therefore, an open-source modular design using MEMS microphones and 3D printing is proposed for selectively capturing frequency-dependent spatial components of sound-fields. Following a modular paradigm, the presented device is low cost and decomposes the array into smaller units (a matrix, connectors and microphones), which can be easily rearranged to capture up to third-order spherical harmonic signals with various physical configurations.
