==METHOD AND DEVICE FOR DECODING SIGNALS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240046938 titled 'METHOD AND DEVICE FOR DECODING SIGNALS

==Simplified Explanation==

The abstract describes a method for decoding signals using spectral coefficients. The computing device groups the coefficients into sub-bands and classifies them as bit allocation unsaturated based on the average number of allocated bits per coefficient and a threshold. It then obtains a noise filling gain based on the sub-band's envelope and performs noise filling to obtain a reconstructed coefficient. Finally, it obtains a frequency domain audio signal based on the decoded coefficients and the reconstructed coefficient.

* The method decodes signals by grouping spectral coefficients into sub-bands.

==Original Abstract Submitted==

in a method to decode signals, a computing device decodes spectral coefficients of a current frame are grouped into a plurality of sub-bands. the computing device classifies a sub-band as a bit allocation unsaturated sub-band based on an average quantity of allocated bits per spectral coefficient of a sub-band of the plurality of sub-bands and a threshold. the computing device obtains a noise filling gain based on an envelope of the sub-band, and obtains a reconstructed spectral coefficient of the sub-band by performing noise filling based on the noise filling gain. the computing device then obtains a frequency domain audio signal based on spectral coefficients in the sub-band obtained by decoding and the reconstructed spectral coefficient.
