Abstract
Embodiments of this application disclose an audio signal encoding and decoding method, including: obtaining, based on spectra of M blocks of a current frame of a to-be-encoded audio signal, M transient state identifiers of the M blocks, where the M blocks include a first block, and a transient state identifier of the first block indicates that the first block is a transient state block, or indicates that the first block is a non-transient state block; obtaining group information of the M blocks based on the M transient state identifiers of the M blocks; performing grouping and arranging on the spectra of the M blocks based on the group information of the M blocks, to obtain a to-be-encoded spectrum of the current frame; encoding the to-be-encoded spectrum by using an encoding neural network to obtain a spectrum encoding result; and writing the spectrum encoding result into a bitstream.
