A data processing apparatus () includes a signal processing unit () and an insertion/deletion unit (). The signal processing unit performs predetermined signal processing on the wirelessly received data for each frame that includes a predetermined number of samples, and stores the data in the buffers (). In the case where an amount of the data accumulated in the buffer is out of a predetermined range, the insertion/deletion unit () performs insertion/deletion processing that inserts or deletes the data in units of samples.

Data processing apparatus, data processing method, and data processing program

Techniques for wireless transmission of data are provided, in which data representing a plurality of frames of a time-sequential signal are encoded. The encoded data are temporarily retained in a memory buffer before wireless transmission. A current number of frames of the encoded data awaiting transmission is determined, and a compression rate is selected for encoding the next frame of data of the time-sequential signal based on the determined number of stored frames in the memory buffer. The selected compression rate is used to encode the next frame of the time-sequential signal, which is added to the encoded data stored in the memory buffer and wirelessly transmitted from the memory buffer. The present disclosure is applicable to a smartphone and a portable player, for example.

Transmission device, transmission method, and program

The present technology relates to a reception terminal and a method capable of achieving stable voice transmission regardless of the device. A reception terminal receives a packet transmitted from a transmission terminal, the packet including main data and redundant data generated on the basis of a redundancy degree determined on the basis of a retransmission timeout period that is a time determined by a combination of the transmission and reception terminals and in which retransmission processing of the main data can be repeatedly executed and used for restoration or interpolation of the main data, and decodes reproduction data by decoding the main data or the redundant data. The present technology can be applied to a communication system that performs voice transmission using BLE.

Reception terminal and method

The present technology relates to a transmission unit, a transmission method, a reception unit, a reception method, and a program that make it possible to easily switch delay time. The transmission unit transmits, by wireless communication, data control information for controlling a usage of data in the reception unit receiving data transmitted by wireless communication, delay control information indicating a delay mode regarding delay time when the data is processed in the reception unit, and data. The reception unit receives the data transmitted by the wireless communication, the data control information, and the delay control information, controls the usage of the data in accordance with the data control information and the delay control information, and outputs data with the usage being controlled. The technology is applicable to, for example, a wireless communication system, etc. where transmission and reception of acoustics are performed by wireless communication such as Bluetooth (registered trademark).

Signal processing apparatus, signal processing method, and program

An earplug unit includes a signal processing unit. The earplug unit is inserted into an external auditory canal and then used. In the earplug unit, a speaker is arranged at an eardrum side, and a microphone is arranged at a side opposite to the eardrum side. The microphone collects a sound in which a user's head shape or auricle characteristic is reflected. An output signal of the microphone is amplification-processed by a volume adjusting unit and then supplied to the speaker. An amplified sound is output from the speaker. A frequency characteristic is smoothed in a band larger than at least an audible frequency band in a system from the microphone to the speaker.

Acoustic device and method of detecting abnormal sound

There is provided a signal processing apparatus including a provision control unit that provides choices expressed subjectively and associated with control for an acoustic signal, and an output unit that outputs a predetermined choice selected from the provided choices.

Information processing device and method and program

A headphone device includes: two output units for outputting playback audio which has been played back; a contact determination unit determining the occurrence of contact with respect to a telephone device; a first audio-collecting unit for collecting call voice generated from the telephone device; a second audio-collecting unit for collecting ambient external sound; and an output audio control unit performing control so that the call voice is outputted from one output unit of the two output units and the external sound is outputted from the other output unit when it is determined that contact has occurred by the contact determination unit.

Headphone device

A playback apparatus is able to present song categories to the user that are suited to the current environmental noise. An audio pickup picks up noise data of the surrounding environment. A noise analyzer analyzes the noise data, and then extracts characteristic quantities expressing the characteristics of the noise data. A noise categorizer categorizes the noise data on the basis of the extracted noise data characteristic quantities. A content category database stores content data recorded onto a recording medium in association with categories based on characteristic quantities of the content data. A content category selector cross-references the noise data categorization result with the content category database, and on the basis thereof, selects a plurality of content data categories from among the categorized content data recorded onto the recording medium. A display unit then displays the selected plurality of content data categories.
