An audio interface is connected to a computer, and an audio signal is input to the computer. A mixer module of the computer mixes an audio signal effect-processed by an ASIO application and an audio signal reproduced by a WDM application, outputs the mixed audio signal to the audio interface, and to the WDM application, and records the sound. The mixer module automatically switches between presence/absence of the effect process and between presence/absence of mixing according to a mode which is set in an operation panel.

Abstract: Embodiments relate to crosstalk cancellation to reduce crosstalk vibrations during use of multiple bone conduction transducers. A system, for example, a head-mounted display (HMD) for providing audio to a user, uses vibration sensors to detect vibrations caused by the bone conduction transducers. In particular, a vibration sensor may generate an error signal representing residual vibrations due to crosstalk at a given ear region of the user. The system uses estimated transfer functions for noise propagation paths through the user's head to generate an anti-crosstalk signal. In response to the anti-crosstalk signal, a bone conduction transducer transmits anti-crosstalk vibrations that reduce the error signal at the given ear region.

Abstract: An audio device may be configured to produce output audio and to capture input audio for speech recognition. In some cases, a second device may also be used to capture input audio to improve isolation of input audio with respect to the output audio.

AEC may be implemented by an adaptive filter based on dynamically optimized filter coefficients. The filter coefficients may be analyzed to detect situations in which the first and second devices are too close to each other, and the user may then be prompted to increase the distance between the two devices.

Abstract: The present disclosure enables applications of a computing system to coordinate object-based audio resources by the use of a minimum resource working set. The minimum resource working set encourages an application to be fair in its requirements since specifying a large number will most likely result in the application receiving zero resources, or losing all of its resources to another application. A working set, which can include a minimum and a maximum working set, also provides a useful metric for the spatial audio resource manager to use when balancing demand. In addition, a minimum working set provides a performance metric for resource balancing since it exposes what the minimum functional requirement is from the maxim requested resource claim.
