摘要： For example, it becomes possible to suppress an increase in hardware scale and costs and to perform signal processing according to an input signal. Provided is an information processing apparatus including a filter processing unit that performs filtering on an input signal, and a filter setting unit that makes a setting of the filtering such that a sound of a target audio source type in the input signal is controlled and the setting is determined using an estimation result obtained from the input signal by an estimation algorithm.

摘要： The invention relates to a method for calibrating a loudspeaker system in an acoustic environment. The method comprises steps of providing a local frequency response based on a recorded test signal and providing a target frequency response. A difference frequency response is established based on a difference between the local frequency response and the target frequency response. A list of exclusion frequency ranges associated with minima of the local frequency response is generated and one or more filter frequency ranges which are non-overlapping with the exclusion frequency ranges are identified. A target filter frequency is selected from the identified filter frequency ranges and a calibration filter related to the target filter frequency is implemented in an equalizer of the loudspeaker system. The invention further relates to a loudspeaker system arranged to carry out the above method for calibrating a loudspeaker system.

摘要： Methods and apparatus are provided for automatically adjusting, by an audio device, the SPL of its audio output. As described herein, the SPL is adjusted based on detected ambient noise. According to aspects, audio device iteratively adjusts the SPL based on the ambient noise. According to aspects, the SPL is adjusted to be greater than the ambient noise by a threshold SPL amount. According to aspects, the audio device outputs sound in substantially a first direction and the microphone detects sound substantially outside of the first direction. The adjusted sounds are output by the audio device.

摘要： Disclosed herein are example techniques to facilitate calibrating a portable playback device. An example implementation involves determining that a playback device is to perform an equalization calibration of the playback device and initiating the equalization calibration. Initiating the equalization calibration involves (i) outputting audio content, (ii) capturing audio data representing reflections of the audio content within an area in which the playback device is located, (iii) determining an acoustic response of the area in which the playback device is located, (iv) selecting a stored acoustic response from the acoustic response database that is most similar to the determined acoustic response of the area in which the playback device is located, and (v) applying to the audio content, via the playback device, a set of stored audio calibration settings associated with the selected stored acoustic area response.
