摘要： A sound field coding system and method that provides flexible capture, distribution, and reproduction of immersive audio recordings encoded in a generic digital audio format compatible with standard two-channel or multi-channel reproduction systems. This end-to-end system and method mitigates any impractical need for standard multi-channel microphone array configurations in consumer mobile devices such as smart phones or cameras. The system and method capture and spatially encode two-channel or multi-channel immersive audio signals that are compatible with legacy playback systems from flexible multi-channel microphone array configurations.

摘要： The invention regards an audio device and comprises a microphone and a sound canal allowing sound to pass from the surroundings to the microphone. Further a signal path from the microphone to a receiver is provided and powered by a current source, such that sounds received at the microphone may be enhanced and presented at the ear level of the user. According to the invention a protection screen is provided at the sound canal, whereby the screen comprises a first surface which faces the surroundings and a second surface which faces the sound canal whereby the screen has a slit formed opening between the first surface and the second surface whereby the transition between the first surface and the slit formed opening is smooth and gradual, and whereby a sharp edge forms the transition between the second surface and the slit formed opening.

摘要： In a system and method for maintaining the spatial stability of a sound field a balance gain may be calculated for two or more microphone signals. The balance gain may be associated with a spatial image in the sound field. Signal values may be calculated for each of the microphone. The signal values may be signal estimates or signal gains calculated to improve a characteristic of the microphone signals. The differences between the signal values associated with each microphone signal may be limited although some difference between signal values may be allowable. One or more microphone signals are adjusted responsive to the two or more balance gains and the signal gains to maintain the spatial stability of the sound field. The adjustments of one or more microphone signals may include mixing of two or more microphone. The signal gains are applied to the two or more microphone signals.
