摘要： The amount of computation in an acoustic signal decoding apparatus for a signal transform process from a frequency domain to a time domain is reduced while realizing the generation of appropriate output acoustic signals.An output control unit 340 receives, from a code string separating unit 310, pieces of window information including a window shape showing the type window function related to a windowing process of input channels, and, if all the pieces of window information are the same, switches the connections of output switching units 351 to 355 to a frequency domain mixing unit 510. The frequency domain mixing unit 510 mixes frequency domain signals of five channels supplied from a decoding/dequantizing unit 320 on the basis of downmix information that causes the number of output channels to be smaller than the number of input channels. IMDC/windowing processing units 521 and 522 transform frequency domain signals of two channels output from the frequency domain mixing unit 510 into time domain signals, thereby outputting the signals as acoustic signals of two channels.

摘要： A method for encoding sound signals on multiple channels includes extracting an arbitrary number of sine waves from each of the sound signals. The sine waves include at least a first sine wave, extracted from a first one of the channels and having first-channel information, and a second sine wave, extracted from a second one of the channels and having second-channel information. Using the first-channel information and one of the second-channel information and sine wave information corresponding to a predetermined sine wave, one of the second-channel information and the sine wave information corresponding to the predetermined sine wave is selected as a to-be-correlated object for encoding in a correlation with the first-channel information. The correlation includes a frequency-based absolute value of a difference between frequency information included in the first-channel information and frequency information included in the second-channel information and is used to encode the first- and second-channel information.

摘要： In an acoustic signal encoding apparatus (100), a tonal noise verification unit (110) verifies whether the input acoustic time-domain signals are tonal or noisy. If the input acoustic time-domain signals are tonal, tonal component signals are extracted by a tonal component extraction unit (121), and tonal component parameters are normalized and quantized in a normalization/quantization unit (122). The residual time-domain signals, obtained on extracting the tonal component signals from the acoustic time-domain signals, are transformed by an orthogonal transforming unit (131) into the spectral information, which spectral information is normalized and quantized by a normalization/quantization unit (132). A code string generating unit (140) generates a code string from the quantized tonal component parameters and the quantized residual component spectral information.

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： The present invention relates to encoding apparatuses which allow encoding to be performed such that the occurrence of pre-echo and post-echo is suppressed. A predetermined waveform analysis is applied to a low-frequency-component input time-sequential signal which includes a high-frequency component occurring at a specific time, and a low-frequency-component time-sequential signal like that shown in FIG. 9A is generated according to a result of the analysis. The low-frequency-component time-sequential signal is removed from the input time-sequential signal to generate a residual time-sequential signal like that shown in FIG. 9B. An amplitude control process is applied such that the amplitude of the residual time-sequential signal is made almost constant in a block which serves as a unit of encoding to generate a time-sequential signal to be quantized, like that shown in FIG. 9C. The time-sequential signal to be quantized is quantized and encoded. The present invention can be applied to audio recording and reproduction apparatuses.

摘要： Upon reception of the group ID and sound volume control signal, a selecting means refers to a control group ID management memory to determined whether the part being supplied belongs to the received group ID or not. When it is determined that the part being supplied belongs to the received group ID, the selecting means transmits the sound volume control signal supplied to the control means. The control means receives this sound volume control signal received from the selecting means and executes the process corresponding to the sound volume control signal for the supplied signal (MIDI signal or audio signal) and then outputs such sound volume control signal. As explained above, the control manipulation in the receiving side can be simplified.
