    "description": "<p>Room Impulse Response (RIR) measurements are one of the most common ways to capture acoustic characteristics<br>\nof a given space. When performed with microphone arrays, the RIRs inherently contain directional information.<br>\nDue to the growing interest in Ambisonics and audio for Virtual Reality, new spherical microphone arrays recently<br>\nhit the market. Accordingly, several databases of Directional RIRs (DRIRs) measured with such arrays, referred to<br>\nas Ambisonics DRIRs, have been publicly released. However, there is no format consensus among databases. With<br>\nthe aim of improving interoperability, we propose an exchange format for Ambisonics DRIRs, as a new Spatially<br>\nOriented Format for Acoustics (SOFA) convention. As a use-case, some existing databases have been converted<br>\nand released following our proposal.</p>",
