Method and apparatus for processing audio signals

TL;DR: In this paper, the authors proposed an encoding device and method, and a decoding device and a program which enable music signals to be played with higher sound quality by expanding a frequency band.

TL;DR: In this article, the authors propose a signal processing method for demultiplexing input encoded data into data including information for a segment including frames and coefficients for a coefficient selected in the frames of the segment, and low band encoded data, decoding the low-band encoded data to produce a low band signal, selecting a coefficient of a frame to be processed from a plurality of the coefficients based on the data, calculating a high band sub-band power of a high-band subband signal of each subband constituting the high band signal of the frame, and producing the

TL;DR: In this article, a bottom-up auditory attention model was used to select emotionally salient parts of speech and execute emotion recognition only on the salient part of speech while ignoring the rest of the speech signal.

TL;DR: In this article, the presence of a user's face may be identified during speech during an interval of time, based on one or more facial orientation characteristics associated with the face during speech.

TL;DR: In this paper, an apparatus for determining a spatial output multi-channel audio signal based on an input audio signal and an input parameter is presented. But the authors do not specify the parameters of the audio signal.

TL;DR: In this article, a disparity calculator calculates a maximum disparity of the object area between the L and R viewpoint images, and a sound image locating unit determines the shift amount of a reverberation sound ratio from a standard ratio based on the object size and the maximum disparity, to give an appropriate depth to sound data.

TL;DR: In this article, a method and device for generating, playing audio signals and a processing system for audio signals are provided, where the distance information of the audio signals which is corresponding to the position of a view point is generated according to the acquired direction information of audio signals.
