Audio Signal Encoding Method and Apparatus
This abstract first appeared for US patent application 20240428807 titled 'Audio Signal Encoding Method and Apparatus
Original Abstract Submitted
an encoding method includes determining an adaptive broadening factor based on a quantized line spectral frequency (lsf) vector of a first channel of a current frame of an audio signal and an lsf vector of a second channel of the current frame, and writing the quantized lsf vector and the adaptive broadening factor into a bitstream.
