摘要： PROBLEM TO BE SOLVED: To automatically select a musical piece which is easy to listen to, even in noisy environment. SOLUTION: A frequency analysis section 31 applies frequency analysis to noise data T of environmental noise collected by a microphone, to obtain frequency information S. An envelope analysis section 32 and a power analysis section 33 analyzes an envelope and power based on the frequency information S, to calculate envelope information Pe and power information Pp, respectively. On the basis of the envelope information Pe and the power information Pp, a noise determination section 34 classifies the environmental noise by referring to a noise parameter database 35 to create noise information indicative of the classification result. A category selecting section 36 selects a category of the musical piece according to classification of the environmental noise, based on the noise information. For example, when the environmental noise is classified into "vehicle", a category "rock" is selected. When the environmental noise is classified into "tea room", a category "classic" is selected.

摘要： PROBLEM TO BE SOLVED: To allow encoding to be performed in such a manner that the occurrence of pre-echo and post-echo is suppressed. SOLUTION: A predetermined waveform analysis is performed to a low-frequency-component input time-series signal which includes a high-frequency component occurring at a specific time, and a low-frequency-component time-series signal as shown in Fig.9A is generated, based on the analysis result. The low-frequency-component time-series signal is removed from the input time-series signal to generate a residual time-series signal as shown in Fig.9B. Amplitude control is performed such that the amplitude of the residual time-series signal is made almost constant in a block which serves as a unit of encoding to generate a time-series signal to be quantized as shown in Fig.9C. The time-series signal to be quantized is quantized and encoded. The present invention can be applied to audio recording and reproduction apparatuses. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To effectively utilize memory resources by reducing the holding number of filter character information of a NC (noise canceling) filter when different NC modes are set so as to be variable, and to reduce user's sense of incongruity due to the change of sound quality when the NC mode is switched. SOLUTION: Filter processing is individually performed by entering a sound collection signal by a microphone, and each filter processing output is combined with a required combination ratio. Thereby, as an intermediate signal characteristic by multiplication of the plurality of filter characteristics is given to the sound collection signal, it is not required that the filter characteristic is related to the NC mode one by one, as in the prior art. Moreover, when the combination ratio is changed with time, sudden change of sound quality is prevented, and user's sense of incongruity is reduced. COPYRIGHT: (C)2010,JPO&INPIT

摘要： The present invention relates to an encoding device and an encoding method, a decoding device and a decoding method, and a program that reduce deterioration of sound quality due to encoding of audio signals. An envelope emphasis part (51) emphasizes an envelope (ENV). A noise shaping part (52) divides an emphasized envelope (D) formed by emphasis of the envelope (ENV) by a value larger than 1, and subtracts noise shaping (G) specified by information (NS) from a result of the division. A quantization part (14) sets a result of the subtraction as a quantization bit count (WL), and quantizes a normalized spectrum (S1) formed by normalization of a spectrum (S0) based on the quantization bit count (WL). A multiplexing part (53) multiplexes the information (NS), a quantized spectrum (QS) formed by quantization of the normalized spectrum (S1), and the envelope (ENV). The present invention can be applied to an encoding device encoding audio signals, for example.

摘要： The present invention relates to an encoding device for saving the number of bits of codes. In step S11, the differential value between a normalization coefficient Bi to be encoded and a normalization coefficient Bi-1 for an encoding unit Ai-1 in a band adjacent to the lower side of an encoding unit Ai corresponding to the normalization coefficient Bi is computed. In step S12, reference is made to a table in which a differential value having a high frequency of occurrence is associated with a code having a small number of bits, and a code corresponding to the computed differential value is read. In step S13, it is determined whether or not all normalization coefficients B have been encoded. If it is determined that all normalization coefficients B have been encoded, in step S14, the code read in step S12 is output. The present invention is applicable to an audio recorder.

摘要： In a signal encoding apparatus (1) a frequency normalization unit (11) normalizes each spectrum of spectral signals by using respectively normalization factors and supplies a normalization factor index per spectrum to a quantization accuracy determining unit (13). The quantization accuracy determining unit (13) adds a weighting factor using auditory properties to the normalization factor index per spectrum of range conversion spectral signals which are subjected to normalization as well as range conversion, and the quantization accuracy is determined according to the result of addition. Then, a quantization unit (14) performs quantization with the quantization accuracy corresponding to a quantization accuracy index supplied from the quantization accuracy determining unit (13), while the encoding/code string generating unit (15) encodes the weighting factor supplied from the quantization accuracy determining unit (13), together with the normalization factor index and the quantized spectral signal.
