The method includes obtaining a first speech signal acquired by a first device; performing frame blocking on the first speech signal, to obtain multiple speech signal frames; converting the multiple speech signal frames into multiple first frequency domain signal frames; performing aliasing processing on a first sub-frequency domain signal frame among the multiple first frequency domain signal frames with a frequency lower than or equal to a target frequency threshold, and retaining a second sub-frequency domain signal frame among the multiple first frequency domain signal frames with a frequency higher than the target frequency threshold, to obtain multiple second frequency domain signal frames, the target frequency threshold being related to a sampling frequency of a second device; and performing frame fusion on the multiple second frequency domain signal frames, to obtain a second speech signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for post-processing audio signal, storage medium, and electronic device","description":"This application discloses a method and an apparatus for processing an audio signal.
