Audio processing method and apparatus, electronic device, and computer-readable storage medium

An electronic device, comprising:

• a memory storing a computer program;
• and
• a processor, wherein
• the processor, when executing the computer program, is configured to:
• obtain a target dry audio, and determine a beginning and ending time of each lyric word in the target dry audio;
• detect a pitch of the target dry audio and a fundamental frequency during the beginning and ending time, and determine a current pitch name of the lyric word based on the fundamental frequency and the pitch;
• tune up the lyric word by a first key interval to obtain a first harmony, and tune up the lyric word by different second key intervals respectively to obtain different second harmonies, wherein
• the first key interval indicates a positive integer number of keys,
• each of the second key intervals is a sum of the first key interval and a third key interval, and different ones of the second key intervals are determined from different third key intervals, and
• the first key interval is different form the third key interval by one order of magnitude;
• and
• synthesize the first harmony and the second harmonies to form a multi-track harmony;
• and mix the multi-track harmony with the target dry audio to obtain a synthesized dry audio.
