Abstract: Audio mixed reality devices and systems that may enhance, diminish, or modify real-world sounds, such as by overlaying audio streams onto real-world sounds or by combining audio streams with real-world sounds. The audio mixed reality devices and systems may enable presence in the real world, immersion in audio streams, or focus on real-world sounds. Immersive spatial audio scenes may be layered over or otherwise used to modify real-world sounds. An audio mixed reality device may capture and reproduce real-world sounds such that they appear spatially situated in the user's environment. The resulting auditory experience may ensure that real-world sounds maintain their natural origin points, thereby providing an acoustic foundation upon which audio streams can be overlaid or modulated without disorienting the user.

Abstract: Utilizing in-canal microphones and other microphones in wearable devices is described. One embodiment is an ear-worn device that includes an in-canal microphone configured to capture sounds in an ear canal and an array of microphones configured to capture external sounds. The ear-worn device may utilize the in-canal microphone to determine if the user is actively speaking. Upon such a determination, the ear-worn device may turn on the array of microphones to capture the user's voice and perform beamforming to focus the array of microphones on the user's mouth. Such speech can then be processed and provided to an artificial intelligence agent. The ear-worn device may switch between using the in-canal microphone and the array of microphones to capture the user's voice depending on environmental noise, the context of the user, and the voice content. The ear-worn device may also blend captures from the in-canal microphone and the array of microphones.

Abstract: An example method includes receiving audio signals associated with virtual auditory space locations. Digital filters are selected based on the virtual auditory space locations. The digital filters include one or more notch filters including one or more center frequencies that are based on generally sigmoidal distributions of center frequencies as a function of virtual auditory space location. The notch filters are configured to produce one or more notches in frequency spectrums of audio signals when applied to the audio signals. The digital filters are applied to the audio signals to obtain processed audio signals. Output audio signals are generated based on the processed audio signals. The output audio signals are provided to devices for producing virtual auditory display sound.
