摘要： An apparatus and a method for encoding an input signal on the time base through orthogonal transform involves removing the correlation of signal waveform on the basis of the parameters obtained by means of linear predictive coding (LPC) analysis and pitch analysis of the input signal on the time base prior to the orthogonal transform. The time base input signal from input terminal is sent to a normalization circuit section and a LPC analysis circuit. The normalization circuit section removes the correlation of the signal waveform and takes out the residue by an LPC inverse filter and pitch inverse filter and sends the residue to an orthogonal transform circuit section. The LPC parameters from the LPC analysis circuit and the pitch parameters from the pitch analysis circuit are sent to a bit allocation calculation circuit. A coefficient quantization section quantizes the coefficients from the orthogonal transform circuit section according to the number of allocated bits from the bit allocation calculation section.

摘要： First, at step S1, i=0 is set. At step S2, data comprising M samples is fetched. At step S3, an M-point DFT is applied to the data fetched at step S2 above. At step S4, an obtained y(k) is multiplied by a twist coefficient w(i, k). The result is placed in y(k). At step S5, the value in y(k) is overwritten to an array x which contains original data. The above processing is repeated N/M times through steps S6 and S7 until all the input data is processed. At step S9, an FFT with N/M (=2n) points is performed within the range of 0≦k

摘要： An apparatus and method for preventing a computation error of band-by-band bit allocation between an encoder and a decoder. In the encoder, an input LSP (line spectrum pair) coefficient is quantized by a quantization device, and a quantized output is output. In a codebook referring section, the look up of a codebook in which computation results are prestored is performed by using an LSP index of the first stage, and band-by-band bit allocation information is created. LSP indexes for each quantization stage are supplied to a decoder. In the decoder, the look up of the codebook is performed using the LSP index, and dequantization is performed on the basis of the created band-by-band bit allocation information.

摘要： Music contents assigned to play lists are reproduced so as to correspond to user's preference. A music content database 7 has stored a plurality of music contents. A CPU 3 creates genre ranks such that music contents that have been more frequently, for example, reproduced are more highly ranked. In addition, the CPU 3 creates play lists corresponding, for example, to tempos and stores the created play lists in a play list database 8. The CPU 3 selects a play list corresponding to a moving tempo obtained from a tempo detection section 9 and selects music content categorized as a highly ranked genre in the genre ranks from those corresponding to the selected play list. The selected music content is supplied to a decoder and amplifier section 12 and then reproduced from a head phone 14.

摘要： Content is selected on the basis of changes of a walking tempo. The walking tempo is detected (S5). In a state determination process (S7), it is determined whether the walking tempo tends to increase, be constant, or decrease. A walking tempo corrective coefficient is calculated on the basis of the determined result and a corrective walking tempo is calculated with the walking tempo corrective coefficient (S9). It is determined whether or not music is changed on the basis of the corrective walking tempo rather than the actually detected walking tempo (S11). When music is changed, relevant music content is searched. Controls are performed in such a manner that when the walking tempo is decreasing, the foregoing state is kept for a while, when the walking tempo is increasing, music is quickly selected according to the increase of the walking tempo, and when the walking tempo is stable, music is not selected.
