AB  - Microphone recording in a room is ideally carried out by using a close distance microphone to prevent reverberation and noise annoyances, but this restricts the flexibility and the surface covered by the recording. When using multiple distant microphones, a microphone selection algorithm is needed for selecting the momentarily best microphone, namely the one with the least reverberation. Given several microphones arbitrarily distributed in a room, this paper describes an algorithm which, based on an estimation of the direct-to-reverberation ratio for each microphone, switches to the best microphone. The algorithm allows prioritizing a microphone and compensation of different directivity patterns.
