Abstract: The present disclosure provides a bit allocation method and apparatus for an audio signal. The bit allocation method for an audio signal includes: obtaining T audio signals in a current frame, where T is a positive integer; determining a first audio signal set based on the T audio signals, where the first audio signal set includes M audio signals, M is a positive integer, T≥M; determining M priorities of the M audio signals in the first audio signal set; and performing bit allocation on the M audio signals based on the M priorities of the M audio signals.

Abstract: A stereo audio signal delay estimation method includes obtaining a current frame of a stereo audio signal. The current frame includes a first channel audio signal and a second channel audio signal. Estimating an inter-channel time (ITD) of the current frame using a first algorithm when a signal type of a noise signal included in the current frame is a coherent noise signal type, or estimating the ITD using a second algorithm when the signal type of the noise signal is a diffuse noise signal type. The first algorithm includes weighting a frequency domain cross power spectrum based on a first weighting function that includes a first construction factor. The second algorithm includes weighting the frequency domain cross power spectrum based on a second weighting function that includes a second construction factor different from the first construction factor.
