Sound file sound quality identification method and apparatus

A sound file sound quality identification method, comprising:

• converting a format of a to-be-identified sound file into a preset reference audio format;
• performing framing on the to-be-identified sound file to obtain a plurality of frames of the to-be-identified sound file;
• performing Fourier transformation processing on the to-be-identified sound file in the reference audio format, to obtain a spectrum of each frame of the to-be-identified sound file;
• performing model matching according to the spectrum of each frame of the to-be-identified sound file, to obtain a preliminary classification result of the to-be-identified sound file;
• and
• determining a sound quality of the to-be-identified sound file according to the preliminary classification result of the to-be-identified sound file.
