A noise cancellation signal generation device includes a reference sensor; a speaker that outputs sound based on a noise cancellation signal a memory that records second information for obtaining a filter coefficient of a noise cancellation filter calculated on the basis of first information obtained in consideration of a change in a relative position between the speaker and a noise cancellation point and a noise cancellation processor that acquires the second information from the memory using a signal acquired by a sensor, and generates the noise cancellation signal on the basis of the filter coefficient obtained from the acquired second information and a reference signal acquired by the reference sensor.

Noise cancellation signal generation device and method thereof

To provide a mechanism for selectively taking an external sound from an appropriate sound source into an internal space of a moving object. An information processing apparatus including an acquisition unit configured to acquire an audio signal from a sound source existing outside a moving object, a generation unit configured to generate an audio signal from a target sound source at a distance from the moving object, the distance being a distance according to a speed of the moving object, of the sound sources, on the basis of the audio signal acquired by the acquisition unit, and an output control unit configured to output the audio signal generated by the generation unit toward an internal space of the moving object.

Information processing apparatus, information processing method, and recording medium

Provided is an information processor including a signal processing section that acquires a first signal to be detected by an acoustic input section of a first unit including the acoustic input section disposed within a predetermined distance from one ear hole of a user in a state of being worn by the user, acquires a second signal, which indicates a noise generated from a noise source, to be acquired by a second unit, and generates a noise cancellation signal directed to the noise on the basis of the first signal and the second signal.

Information processor, information processing system, and information processing method

A signal processing apparatus includes a signal processor configured to: generate a first noise reduction signal using an adaptive filter based on a signal output from a first input apparatus, and cause the generated first noise reduction signal to be output by a first output apparatus; and generate a second noise reduction signal using a feedback filter based on a signal output from a second input apparatus, and cause the generated second noise reduction signal to be output by a second output apparatus. The feedback filter has a fixed feedback coefficient. The first input apparatus is located at a first noise-cancellation target location in an environment, and the second input apparatus is located at a second noise-cancellation target location in the environment, which may be different from the first noise-cancellation target location.

Signal processing apparatus, method, and program

By allowing the movement of a user to affect the playback of content, the entertainment characteristic or uplifting spirits derived from content playback itself can be enhanced. The timing at which the user places his/her foot on the ground while walking or the timing at which the user shakes or changes from swinging in one direction to swinging to another direction is detected. Then, content, such as a music piece or moving pictures, is played back by allowing the timing of beats or bars of the music piece or the timing of scene changes or cut changes of the moving pictures to be synchronized with the timing of the movement of the user.

Content playback method and content playback apparatus

[Object] To provide a signal processing device, a signal processing method, and a program. [Solution] The signal processing device includes: a first arithmetic processing unit that performs first suppressing processing for suppressing a first audio signal based on a first microphone on a basis of a second audio signal based on a second microphone; and a second arithmetic processing unit that performs second suppressing processing for suppressing the second audio signal on a basis of the first audio signal.

Signal processing device, signal processing method, and program

The present technology relates to a sound processing device, a sound processing method, and a program, which can collect a desired sound. A sound processing device includes: a sound collection unit configured to collect a sound; an application unit configured to apply a predetermined filter to a signal of the sound collected by the sound collection unit; a selection unit configured to select a filter coefficient of the filter applied by the application unit; and a correction unit configured to correct the signal from the application unit. The selection unit selects the filter coefficient on the basis of the signal of the sound collected by the sound collection unit. The selection unit creates, on the basis of the signal of the sound collected by the sound collection unit, a histogram which associates a direction where the sound occurs and a strength of the sound and selects the filter coefficient on the basis of the histogram. The present technology can be applied to a sound processing device.

Sound processing device and sound processing method

A content reproducing apparatus is disclosed which includes: a sensor; a discrimination circuit configured to discriminate whether a movement of a user is a first movement or a second movement based on a detection output from the sensor; a storage configured to store contents; a reproduction circuit configured to reproduce the contents; and a control circuit configured to supply the reproduction circuit with contents retrieved from the storage in accordance with a discrimination output from the discrimination circuit.

Content reproducing apparatus, audio reproducing apparatus and content reproducing method

A movement supporting method includes the following steps: detecting a movement tempo of a user; determining whether a movement tempo detection value is within a target range; and outputting a warning when the movement tempo detection value is out of the target range.

Movement supporting method and apparatus

Music contents assigned to play lists are reproduced so as to correspond to user's preference. A music content databasehas stored a plurality of music contents. A CPUcreates genre ranks such that music contents that have been more frequently, for example, reproduced are more highly ranked. In addition, the CPUcreates play lists corresponding, for example, to tempos and stores the created play lists in a play list database. The CPUselects a play list corresponding to a moving tempo obtained from a tempo detection sectionand selects music content categorized as a highly ranked genre in the genre ranks from those corresponding to the selected play list. The selected music content is supplied to a decoder and amplifier sectionand then reproduced from a head phone

Content reproducing apparatus, content reproduction method, and program

A bio-information processing apparatus includes a bio-information sensor for measuring the bio-information of a subject in a non-contact manner and in an unrestricted manner; and a circuit for estimating the psychological state of the subject and the intensity thereof on the basis of the measured value of the bio-information measured using the bio-information sensor and on the basis of an initial value or a standard value of the measured value.

Method and apparatus for processing bio-information

A player apparatus for playing an input signal after band-extending the input signal includes: an extension controller to determine an extension start band for the input signal in accordance with information relating to the input signal; and a band divider to divide the input signal into a plurality of sub-band signals. The frequency band is extended on the basis of a plurality of the sub-band signals on a side lower than the extension start band, among the plurality of sub-band signals into which the input signal is band-divided by the band divider.
