An accessory apparatus includes a housing, an apparatus connector, a plurality of auxiliary accessory interfaces, and an internal microcontroller. The connection connector is configured to mate with a corresponding accessory connector of a physical controller to electrically connect the internal microcontroller to the physical controller. Each auxiliary accessory connector is configured to enable a separate auxiliary user input device to operatively connect to the accessory apparatus and electrically connect with the internal microcontroller. The internal microcontroller is configured to: (1) receive an input control signal from an auxiliary user input device operatively connected to an auxiliary accessory connector of the plurality of auxiliary accessory connectors, (2) map the input control signal to a mapped control signal corresponding to a physical control of the physical controller, and (3) send the mapped control signal to the physical controller via the apparatus connector.

A device for suppressing ambient sounds from speech received by a microphone array is provided. One embodiment of the device comprises a microphone array, a processor, an analog-to-digital converter, and memory comprising instructions stored therein that are executable by the processor. The instructions stored in the memory are configured to receive a plurality of digital sound signals, each digital sound signal based on an analog sound signal originating at the microphone array, receive a multi-channel speaker signal, generate a monophonic approximation signal of the multi-channel speaker signal, apply a linear acoustic echo canceller to suppress a first ambient sound portion of each digital sound signal, generate a combined directionally-adaptive sound signal from a combination of each digital sound signal by a combination of time-invariant and adaptive beamforming techniques, and apply one or more nonlinear noise suppression techniques to suppress a second ambient sound portion of the combined directionally-adaptive sound signal.
