摘要： In band-splitting acoustic signals and subsequently encoding and decoding the band-split signals, band-splitting and band-synthesizing processing with high accuracy is desirable. To this end, an optimizing processor (60) optimizes prototype filter coefficients held on a prototype filter coefficient holder (59) by a window function of a tap length L'. The filter coefficient portions of the optimized prototype filter with both end values equal to zero are discarded for deriving a corrected prototype filter having a tap length L'.

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.

摘要： 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.
