Latest Patent Applications
Haiting Li's latest patent applications include:
1. **Downmixed Signal Calculation Method and Apparatus** - This application discloses a downmixed signal calculation method and apparatus. The method includes: when a current frame or a previous frame of the current frame of a stereo signal is not a switching frame and a residual signal in the current frame or the previous frame does not need to be encoded, obtaining a second downmixed signal in the current frame and a downmix compensation factor of the current frame, correcting the second downmixed signal in the current frame based on the downmix compensation factor of the current frame, to obtain the first downmixed signal in the current frame and determining the first downmixed signal in the current frame as a downmixed signal in the current frame in a preset frequency band.
2. **Method and Apparatus for Determining Weighting Factor During Stereo Signal Encoding** - Various embodiments provide a method and an apparatus for determining a weighting factor during stereo signal encoding. In those embodiments, a parameter value corresponding to the encoding mode of the to-be-encoded signal is determined based on an encoding mode of a to-be-encoded signal in a stereo signal and a correspondence between an encoding mode and a parameter value. Based on the determined parameter value and an energy spectrum of a linear prediction filter corresponding to an original line spectral frequency parameter of the to-be-encoded signal, a weighting factor for calculating a distance between the original line spectral frequency parameter and a target original line spectral frequency parameter is calculated.
Conclusion
