A low-frequency encoding circuit encodes a low-frequency signal with a code amount determined by the high-frequency code amount and a low-frequency decoding circuit decodes the encoded low-frequency signal. A subband dividing circuit divides a decoded low-frequency signal obtained by decoding into decoded low-frequency subband signals of a plurality of subbands and a second high-frequency encoding circuit generates a high-frequency code string such that a code amount of the high-frequency code string for obtaining a high-frequency component is not larger than the high-frequency code amount based on the decoded low-frequency subband signals and the high-frequency subband signals.

摘要： The present invention relates to a control device, a control method, and a program capable of improving operability with a simpler configuration.A reproducing apparatus 11 which reproduces sound such as music includes earphones 21 which are worn by a user on the ears and a body 22. A sound pickup unit 31 collects sounds around the reproducing apparatus 11, and a determination unit 34 extracts future amounts from the collected sound and determines whether the sound corresponds to an operation sound generated when the sound pickup unit 31 is directly tapped by the user. A controller 35 executes a process in accordance with a result of the determination performed by the determination unit 34. For example, when a sound pickup unit 31-1 is tapped once within a predetermined period of time, the controller 35 instructs a reproduction controller 39 to stop reproduction of music. In the reproducing apparatus 11, various function control processes may be performed by a simple operation of tapping the sound pickup unit 31 and buttons are not required. The present invention is applicable to a music player.

摘要： The present technique relates to a sound processing apparatus, a method, and a program capable of alleviating degradation of the quality of sound in a case where the gain of a sound signal is amplified.When equalizer processing for adjusting the gain of each frequency band of an input signal on the basis of a gain setting value is performed, an input signal is attenuated by an input attenuation amount derived from the gain setting value, and the equalizer processing is performed on the input signal attenuated. The amount of amplification of the gain of the input signal in the equalizer processing is estimated on the basis of the gain setting value and a weight coefficient of each frequency band derived from a generally-available music signal prepared in advance, and a difference of the estimation value and the input attenuation amount is calculated as a gain correction amount. Further, nonlinear amplification processing is performed on the input signal so as to actually amplify the input signal, which has been subjected to the equalizer processing, by a gain correction amount, and an output signal is obtained. The present technique can be applied to a sound processing apparatus.

摘要： The present technology relates to a signal processing device, method, and program that may obtain audio at a higher audio quality when decoding an audio signal.An envelope information generating unit 24 generates envelope information representing an envelope form of high frequency components of an audio signal to be encoded. A sine wave information generating unit 26 extracts a sine wave signal from the high frequency components of the audio signal, and generates a sine wave information representing an emergence start position of the sine wave signal. An encoding stream generating unit 27 multiplexes the envelope information, the sine wave information, and low frequency components of the audio signal that have been encoded, and outputs an encoding stream obtained as the result. As a result, the high frequency components included in the sine wave signal may be predicted at a higher accuracy from the envelope information and the sine wave information at the receiving side of the encoding stream. The present invention may be applied to a signal processing device.
