摘要： An energy corrector (105) for correcting a target energy for high-frequency components and a corrective coefficient calculator (106) for calculating an energy corrective coefficient from low-frequency subband signals are newly provided. These processors perform a process for correcting a target energy that is required when a band expanding process is performed on a real number only. Thus, a real subband combining filter and a real band expander which require a smaller amount of calculations can be used instead of a complex subband combining filter and a complex band expander, while maintaining a high sound-quality level, and the required amount of calculations and the apparatus scale can be reduced.

摘要： In the conventional art inventions for coding multi-channel audio signals, three of the major processes involved are: generation of a reverberation signal using an all-pass filter; segmentation of a signal in the time and frequency domains for the purpose of level adjustment; and mixing of a coded binaural signal with an original signal coded up to a fixed crossover frequency. These processes pose the problems mentioned in the present invention. The present invention proposes the following three embodiments: to control the extent of reverberations by dynamically adjusting all-pass filter coefficients with the inter-channel coherence cues; to segment a signal in the time domain finely in the lower frequency region and coarsely in the higher frequency region; and to control a crossover frequency used for mixing based on a bit rate, and if the original signal is coarsely quantized, to mix a downmix signal with an original signal in proportions determined by an inter-channel coherence cue.

摘要： An encoding device (200) includes an MDCT unit (202) that transforms an input signal in a time domain into a frequency spectrum including a lower frequency spectrum, a BWE encoding unit (204) that generates extension data which specifies a higher frequency spectrum at a higher frequency than the lower frequency spectrum, and an encoded data stream generating unit (205) that encodes to output the lower frequency spectrum obtained by the MDCT unit (202) and the extension data obtained by the BWE encoding unit (204). The BWE encoding unit (204) generates as the extension data (i) a first parameter which specifies a lower subband which is to be copied as the higher frequency spectrum from among a plurality of the lower subbands which form the lower frequency spectrum obtained by the MDCT unit (202) and (ii) a second parameter which specifies a gain of the lower subband after being copied.

摘要： A predicted residual signal is calculated from a current input speech signal and a past input speech signal, and a cross-correlation between the predicted residual signal and the past input speech signal having one speech sub-frame length stored in a first code book is calculated. In cases where the current input speech signal has no local peak, the cross-correlation becomes high, so that a synthesized speech signal is generated from the past input speech signal stored in the first code book or a predetermined sound source signal having one speech sub-frame length stored in the second code book. In contrast, in cases where the current input speech signal has a local peak, the cross-correlation becomes low, so that it is judged that a function of the first code book is depressed. In this case, a synthesized speech signal is generated from a group of short-length sound source signals having a total length equal to one speech sub-frame length stored in a short-length signal code book. Therefore, even though the current input speech signal suddenly has a local peak, because the synthesized speech signal is generated from the short-length sound source signals respectively having a speech length lower than one speech sub-frame length, the local peak can be expressed by the short-length sound source signals, an appropriate exciting sound source signal similar to the current input speech signal can be determined, and the synthesized speech signal can be adequately obtained.

长声源信号生成合成语音信号。因此，即使当前输入语音信号突然具有局部峰值，由于合成语音信号是由分别具有低于一个语音子帧长度的语音长度的短长音源信号生成的，所以可以表示局部峰值通过短距离声源信号，可以确定类似于当前输入语音信号的合适的激励声源信号，并且可以适当地获得合成的语音信号。
