Abstract: This application discloses an audio signal processing method and apparatus, and belongs to the field of audio signal processing technologies. The method includes: obtaining a plurality of sub-bands of an audio signal and a scale factor of each sub-band; determining, based on the scale factors of the plurality of sub-bands, a reference value used for shaping a spectral envelope of the audio signal; and shaping the spectral envelope of the audio signal by using the reference value as a baseline, to obtain an adjustment factor of each sub-band corresponding to a shaped spectral envelope. The adjustment factor is used to quantize a spectral value of the audio signal, and/or the adjustment factor is used to dequantize a code value of the spectral value. In this application, compression efficiency of encoding an audio signal is improved while sound quality is ensured.

Abstract: This application discloses an audio data processing method and apparatus, and relates to the field of multimedia technologies. The method includes: obtaining m (m is an integer greater than or equal to 2) audio clips; determining m−1 pieces of transition audio information based on the m audio clips; and generating target medley audio based on the m audio clips and the m 1 pieces of transition audio information. The m−1 pieces of transition audio information are used to splice the m audio clips. First transition audio information in the m−1 pieces of transition audio information is used to splice a first audio clip and a second audio clip that are sorted consecutively in the m audio clips. Sorting of the m audio clips is a medley composition order of the m audio clips.
