A sound signal detection device is closed. The sound signal detection device is connected between an audio output device and a speaker apparatus. The sound signal detection device includes a first connecting port, a second connecting port, a microphone, and a processing module. The first connecting port connects to the audio output device and acquires a first sound signal. The second connecting port is used for outputting the first sound signal to the speaker apparatus. The microphone is used for receiving a second sound signal from the speaker apparatus. The process module is electrically connected to the microphone and used for detecting a volume of the second sound signal to generate a real volume signal.

Example embodiments disclosed herein relate to separated audio analysis and processing. A system for processing an audio signal is disclosed. The system includes an audio analysis module configured to analyze an input audio signal to determine a processing parameter for the input audio signal, the input audio signal being represented in time domain. The system also includes an audio processing module configured to process the input audio signal in parallel with the audio analysis module. The audio processing module includes a time domain filter configured to filter the input audio signal to obtain an output audio signal in the time domain, and a filter controller configured to control a filter coefficient of the time domain filter based on the processing parameter determined by the audio analysis module. Corresponding method and computer program product of processing an audio signal are also disclosed.

A networked speaker system automatically adjusts certain audio speaker system settings based on whether the system is inside a building or has been moved outside as may be sensed by one or capacitors on a speaker. Also, techniques are described for adjusting speaker driver direction based on walls or other barriers in a room or based on the location of a listener.

An audio processing system includes a server complex in communication with a network. The server complex receives a digital audio file and one or more analog domain control settings from a client device across the network. A digital-to-analog converter converts the digital audio file to an analog signal. One or more analog signal processors apply at least one analog modification to the analog signal in accordance with the one or more analog domain control settings. An analog-to-digital converter converts the modified analog signal to a modified digital audio file. The server complex can then deliver the modified digital audio file to the client device across the network.

An information processing apparatus includes a processor that controls display of a graphic including a single shape, where the single shape corresponds to a plurality of content output characteristic adjusting parameters. The processor also modifies the single shape included in the graphic displayed on the display based on input information, and adjusts at least one content output characteristic adjusting parameter of reproduced content based on the input information.

A method and an apparatus for sound effect compensation, a non-transitory computer-readable storage medium, and a terminal device are provided. The method includes the following. An acoustic transmission function of an audio processing device in an ear canal of a user is determined according to an audio signal currently output from the audio processing device. Compensate for the audio signal according to the acoustic transmission function.

A display system includes a head-mounted display unit and a detachable speaker unit. The head-mounted display unit outputs visual content to a user and provides a visual pass-through of a real environment to the user. The detachable speaker unit is detachably coupleable to the head-mounted display unit for providing aural content to the user. At least one of the visual content or the aural content is changed according to a position of the detachable speaker unit relative to the head-mounted display unit.

In one example, a zone player may include a network interface, at least one processor, a non-transitory computer-readable medium, and program instructions stored on the non-transitory computer-readable medium that may be executable by the at least one processor such that the zone player is configured to receive an instruction to change a volume setting of the zone player to a requested volume level; in response to receiving the instruction to change the volume setting of the zone player to the requested volume level, adjust the volume setting of the zone player to an adapted volume level that is lower than the requested volume level; and after adjusting the volume setting of the zone player to the adapted volume level, send an indication that the volume setting of the zone player has been adjusted to the requested volume level rather than the adapted volume level.
