Embodiment Construction
[0083] The concept of the sound quality of audio data involved in the embodiments of the present disclosure is described below:
[0084] Audio data includes songs, voice files, and the like. Taking a song as an example, the sound quality of a song refers to the sound quality perceived by the human ear when the song is played. Among them, the higher the sound quality of the song, the closer the recorded song is to the original state of the sound, which can reflect more the original information of the song; on the contrary, the lower the sound quality of the song, the less effective information the human ear perceives.
[0085] Low-quality sound quality refers to the audio obtained by sampling at a lower sampling rate (such as below 28kHz), denoted as A; or the audio is passed through a lower bit rate encoder (such as LAME 64bits version 3.99.5 encoder at 80kbps and below) Coded at a code rate), the encoded audio with an effective spectral height below 14kHz is recorded as B; t...
