Abstract: Disclosed are technologies for processing a surround sound audio signal. The center channel is processed to generate a processed center channel. For each pair of corresponding left and right audio channels, mid and side channel signals are generated by taking the sum and difference of the pair, respectively. The side channel is outputted to a first signal pathway that features a dynamic range compressor. The mid channel is outputted to a second signal pathway and spectrally decomposed into a plurality of sub-band signals. Each sub-band signal is compressed by a dynamic range compressor and transmitted to a gain stage. The compressed sub-band signals are outputted from the gain stage and recombined. The outputs of the first and second signal pathways are then recombined and decoded to produce processed left and right audio signals. Each pair or processed left and right audio signals are output along with the processed center channel.

Abstract: Disclosed are systems and methods for processing an audio signal on a stereo audio device. Left and right audio signals are encoded as mid and side channel signals by taking the sum and difference of the left and right audio signals, respectively. The side channel is outputted to a first signal pathway that features a dynamic range compressor. The mid channel is outputted to a second signal pathway which is then spectrally decomposed into a plurality of sub-band signals using one or more bandpass filters. Each sub-band signal is then provided to a dynamic range compressor, compressed and outputted to a gain stage. Subsequently, each compressed sub-band signal is outputted from the gain stage and recombined. The outputs of the first and second signal pathways are then recombined and decoded in order to produce left and right audio signals. The left and right audio signals are then outputted.

Abstract: A haptic device configured to provide haptic feedback to a user. In one aspect, a user or part of a user is located on the haptic device including actuators and damping elements. A haptic feedback wave is generated by an actuator and propagated to the user or part of the user on the haptic device. Damping elements receive the haptic feedback wave and suppress the haptic feedback wave to reduce a reflection thereof.

Abstract: An actuator configured to provide haptic feedback to a user. The actuator is located on a plate and is configured to apply various excitations to the plate to generate a mechanical wave propagating in the controlled direction. The excitations can be a translational motion of the actuator (or a portion of the actuator) in two or three perpendicular axes. Alternatively, the excitations can be a non-translational motion (e.g., rotation about an axis) of the actuator (or a portion of the actuator). By generating the mechanical wave traveling in the controlled direction, loss of energy due to scattering of the mechanical wave can be obviated.
