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