摘要： The present invention relates to a signal processing apparatus and method, a program, and a data recording medium configured such that the playback level of an audio signal can be easily and effectively enhanced without requiring prior analysis.An analyzer 21 generates mapping control information in the form of the root mean square of samples in a given segment of a supplied audio signal. A mapping processor 22 takes a nonlinear function determined by the mapping control information taken as a mapping function, and conducts amplitude conversion on a supplied audio signal using the mapping function. In this way, by conducting amplitude conversion of an audio signal using a nonlinear function that changes according to the characteristics in respective segments of an audio signal, the playback level of an audio signal can be easily and effectively enhanced without requiring prior analysis. The present invention may be applied to portable playback apparatus.

摘要： A winding device includes a winding member that rotates to wind a flexible member therearound, a first rotating member that is rotatable, a second rotating member that is rotatable coaxially with the winding member and has a smaller resistance to rotation in a predetermined direction than that to rotation in a direction opposite the predetermined direction, and an engaging member. When the first rotating member is subjected to a first torque, the engaging member brings the winding member, the first rotating member, and the second rotating member into engagement with one another, so that the winding member becomes rotatable together with the first rotating member in the predetermined direction. When the first rotating member is subjected to a second torque in a direction opposite that of the first torque, the engaging member releases the engagement, so that the winding member becomes rotatable in the direction opposite the predetermined direction.

摘要： A sound signal encoder for high efficiency encoding of sound signals from a plurality of channels is provided which includes a to-be-correlated object setter (52), to-be-correlated object selector (56) and a variable-length encoder (58). The to-be-correlated object setter (52) sets, on the basis of left-channel frequency information held in a left-channel frequency information holder (50) and right-channel frequency information held in a right-channel frequency information holder (51), index [i] indicating which ones of sine waves on the left channel are to be correlated with, namely, are to be subtracted from, sine waves on the right channel. The to-be-correlated object selector (56) selects a default value read from a storage unit (55) or index [i]-th amplitude information read from a left-channel amplitude information holder (53) as an object to be subtracted from the i-th amplitude information on the right channel according to the index [i]. The variable-length encoder (58) makes variable-length encoding of a difference resulted from subtraction of the left-channel amplitude information or default value as the to-be-correlated object from the amplitude information on the right channel.

摘要： In an audio-information encoding apparatus, in order to encode an audio signal containing a white-noise component, an index iL indicating the energy level of the white-noise component and an index iR designating the start index of a random-number table are introduced into a code train. In an audio-information decoding apparatus (20), a white-noise generating unit (25) uses the indices iL and iR contained in the code train, thereby generating a white-noise signal Sw(t) on the time axis, which has the same level as the white noise, and an adder (26) adds the white-noise signal to an audio signal Sf(t) decoded on the time axis, outputting as an output audio signal So(t).

摘要： In an encoding apparatus, when difference value between adjacent quantization units of quantization accuracy information where, e.g., distribution range is 0˜7, e.g., if difference value is 3 or more, 8 is subtracted, and if difference value is less than −4, 8 is added to thereby transform two difference values where difference therebetween is 8 into the same value. Thus, the distribution range of difference value becomes −4˜3, and size of code book (table) can be held down to the same size in the case where difference is not taken. In addition, high order 1 bit of difference value may be masked to carry out replacement into value consisting of only low order 3 bits, thus also making it possible to prevent increase in size of code book (table).

摘要： Information is encoded into a code with a smaller number of bits. An encoding apparatus encodes an acoustic time series signal such that the acoustic time series signal is split into band signals in predetermined bands and gain adjustment is made on the band signals, at a gain control position by a gain control amount, for each of as many positions as indicated by a gain control number. Although the gain control number can take any one of values from 0 to 7, it has a high probability of taking a particular value (0, for example). The gain control number is encoded such that a code with a small number of bits is assigned to the gain control number equal to a value having a high-occurrence probability. The encoding is also applied to a voice recording apparatus.
