摘要： The present invention relates to an audio encoding and, more particularly, to a signal classifying method and device, and an audio encoding method and device using the same, which can reduce a delay caused by an encoding mode switching while improving the quality of reconstructed sound. The signal classifying method may comprise the operations of: classifying a current frame into one of a speech signal and a music signal; determining, on the basis of a characteristic parameter obtained from multiple frames, whether a result of the classifying of the current frame includes an error; and correcting the result of the classifying of the current frame in accordance with a result of the determination. By correcting an initial classification result of an audio signal on the basis of a correction parameter, the present invention can determine an optimum coding mode for the characteristic of an audio signal and can prevent frequent coding mode switching between frames.

摘要： The invention relates to the processing of a digital audio signal, including a series of samples distributed in consecutive frames. The processing is implemented in particular when decoding said signal in order to replace at least one signal frame lost during decoding. The method includes the following steps: a) searching, in a valid signal segment available when decoding, for at least one period in the signal, determined in accordance with said valid signal; b) analysing the signal in said period, in order to determine spectral components of the signal in said period; c) synthesising at least one frame for replacing the lost frame, by construction of a synthesis signal from: an addition of components selected among said predetermined spectral components, and a noise added to the addition of components. In particular, the amount of noise added to the addition of components is weighted in accordance with voice information of the valid signal, obtained when decoding.

摘要： A method and device for modifying a synthesis of a time-domain excitation decoded by a time-domain decoder, wherein the synthesis of the decoded time-domain excitation is classified into one of a number of categories. The decoded time-domain excitation is converted into a frequency-domain excitation, and the frequency-domain excitation is modified as a function of the category in which the synthesis of the decoded time-domain excitation is classified. The modified frequency-domain excitation is converted into a modified time-domain excitation, and a synthesis filter is supplied with the modified time-domain excitation to produce a modified synthesis of the decoded time-domain excitation.

摘要： Embodiments for audio classification are described. An audio classification system includes at least one device which executes a process of audio classification on an audio signal. The at least one device can operate in at least two modes requiring different resources. The audio classification system also includes a complexity controller which determines a combination and instructs the at least one device to operate according to the combination. For each of the at least one device, the combination specifies one of the modes of the device, and the resources requirement of the combination does not exceed maximum available resources. By controlling the modes, the audio classification system has improved scalability to an execution environment.

摘要： The invention relates to a method for rendering a musical signal that is compatible with a discontinuous transmission codec, comprising the steps of: detecting a period of silence in an initial musical signal (IS); producing an auxiliary audio signal (SA), having a lower amplitude than that of the initial signal outside of the periods of silence, but sufficient so as to not be detectable as silence, by means of a discontinuous transmission codec; and replacing the initial musical signal (IS) with the auxiliary signal (SS) during the period of silence.

摘要： The invention relates to an audio signal classifier and methods therein for audio signal classification. Embodiments of a method performed by an audio signal classifier comprises, for a segment of the audio signal: identifying a set of spectral peaks and determining a mean distance S between peaks in the set; and determining a ratio, PNR, between a peak envelope energy and a noise floor envelope energy. The method further comprises determining to which class of audio signals, out of a plurality of audio signal classes, the segment belongs, based on at least the mean distance S and the ratio PNR.
