Abstract
A microphone device comprises a microphone array comprising a plurality of microphone elements physically arranged to provide a respective plurality of microphone signals from which a spatially encoded sound-field signal may be produced; a local storage device; a processor; and a wireless transmission module. The device is arranged to store the plurality of microphone signals to the local storage device; to produce, using the processor, a reference signal including at least one of the plurality of microphone signals and a further signal derived therefrom; and to transmit the reference signal via the wireless transmission module.
Claims23
A microphone device comprising:
- a microphone array comprising a plurality of microphone elements physically arranged to provide a plurality of microphone signals from which a spatially encoded sound-field signal may be produced;
- a local storage device;
- a processor;
- and
- a wireless transmitter;
- wherein the microphone device is arranged:
- to store the plurality of microphone signals to the local storage device;
- to produce, using the processor, a reference signal including at least one of the plurality of microphone signals and a further signal derived therefrom;
- and
- to transmit the reference signal via the wireless transmitter.
A method of capturing a sound-field recording in a sound capture system with a microphone device and a further device, comprising:
- obtaining a plurality of microphone signals from a microphone array comprising a plurality of microphone elements;
- storing the plurality of microphone signals to a local storage device in the microphone device;
- using a processor of the microphone device to produce a reference signal including at least one of the plurality of microphone signals and/or a further signal derived therefrom;
- and
- transmitting the reference signal from the microphone device to the further device using a wireless transmitter of the microphone device and a wireless receiver of the fluffier device.
