摘要： Disclosed are an audio encoding device and an audio decoding device which reduce degradation of subjective quality of a decoding signal caused by power mismatch of a decoding signal which is generated by a concealing process upon disappearance of a frame. When a frame is lost, a past encoding parameter is used to obtain a concealed LPC of the current frame and a concealed sound source parameter. A normal CELP decoding is performed from the obtained concealed sound source parameter. Correction is performed by using a conceal parameter on the obtained concealed LPC and the concealed sound source signal. The power of the corrected concealed sound source signal is adjusted to match a reference sound source power. A filter gain of the synthesis filter is adjusted so as to adjust the power of a decoded sound signal to the power of a decoded sound signal during an error-free state. Moreover, a synthesis filter gain adjusting coefficient is calculated by using an estimated normalized residual power so that a filter gain of a synthesis filter formed by using a concealed LPC is a filter gain during an error-free state.

摘要： An audio decoding device capable of suppressing an information amount for a lost flame compensation process and encoding efficiency is provided. A decoded sound source generator generates a lost frame's CELP decoded sound source signal. A pitch pulse information decoder CELP decodes a pitch pulse position information and a pitch pulse amplitude information. A pitch pulse waveform learner learns a pitch pulse learning waveform in a past frame in advance from the lost frame. A convolution adjuster amplitude-adjusts the pitch pulse learning waveform according to the pitch pulse amplitude information by considering a predetermined number of waveforms peripheral to a peak position of the lost frame's CELP decoded excitation signal, and convolutes a pitch pulse waveform into a time axis which has been amplitude-adjusted according to the pitch pulse position information. A sound source signal corrector adds or replaces the pitch pulse waveform convoluted into the time axis to the lost flame decoded sound source signal.

摘要： There is provided an audio encoding device capable of causing a decoding side to freely select an audio decoding mode corresponding to a control method used for audio encoding and capable of generating data which can be decoded even when the decoding side does not correspond to the control method. The audio encoding device (100) outputs encoded data corresponding to an audio signal containing an audio component and encoded data corresponding to an audio signal containing no audio component. An audio encoding unit (102) encodes the input audio signal in a predetermined section unit and generates encoded data. An audio present/absent judgment unit (106) decides whether the input audio signal contains an audio component for each predetermined section. A bit embedding unit (104) performs synthesis of noise data only for those generated from the input audio signal of the voice absent section in the encoded data generated by the audio encoding unit (102), thereby acquiring encoded data corresponding to an audio signal containing an audio component and encoded data corresponding to an audio signal containing no audio component.

摘要： Fluctuation in decoded signal localization is suppressed to maintain the feel of stereo. A selection unit selects balance parameters when the balance parameters are input from a gain coefficient decoding unit, or selects balance parameters input from a gain coefficient calculation unit when there is no balance parameter input from the gain coefficient decoding unit, and outputs the selected balance parameters to a multiplication unit. The multiplication unit multiplies a gain coefficient input from the selection unit with a decoded monaural signal input from a monaural decoding unit to perform balance adjustment processing.

摘要： There is provided an audio encoding device capable of effectively encoding stereo audio in audio encoding having monaural-stereo scalable configuration. In this device, a correlation degree comparison unit (304) calculates correlation in a first channel (correlation degree between the past signal and the current signal in the first channel) from the first channel audio signal and calculates correlation in a second channel (correlation degree between the past signal and the current signal in the second channel) from the second channel audio signal. The correlation in the first channel is compared to the correlation in the second channel. A channel having the greater correlation is selected. According to the selection result of a correlation comparison unit (304), a selection unit (305) selects the first channel prediction signal outputted from a first channel prediction unit (307) or the first channel prediction signal outputted from a first channel signal generation unit (311) and outputs the selected signal to a subtractor (303) and a first channel prediction residual signal encoding unit (308).
