Audio compensation method and apparatus, electronic device, and storage medium

An electronic device, wherein the electronic device comprises:

• one or more processors;
• and
• a storage, configured to store one or more programs that, when executed by the one or more processors, cause the one or more processors to:
• receive an audio signal, and extract and store feature parameters of an audio frame in the audio signal, wherein the feature parameters comprise a spectral feature and a pitch period sequence, and the pitch period sequence comprises pitch periods of sub-frames in the audio frame in sequence;
• in response to detecting a loss of the audio frame, predict the feature parameters of the lost frame according to the feature parameters of a previous audio frame of the lost frame;
• and
• determine an audio signal of the lost frame according to the feature parameters of the lost frame.

A non-transitory storage medium comprising computer-executable instructions that, when executed by a computer processor, cause the computer processor to:

• receive an audio signal, and extract and store feature parameters of an audio frame in the audio signal, wherein the feature parameters comprise a spectral feature and a pitch period sequence, and the pitch period sequence comprises pitch periods of sub-frames in the audio frame in sequence;
• in response to detecting a loss of the audio frame, predict the feature parameters of the lost frame according to the feature parameters of a previous audio frame of the lost frame;
• and
• determine an audio signal of the lost frame according to the feature parameters of the lost frame.
