The invention relates to an audio processing method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-coded target audio clip and a target sound quality index; the target sound quality index is a sound quality index indicated by the target audio clip; performing sound quality index prediction processing on the target audio clip based on a sound quality prediction model to obtain sound quality indexes corresponding to the target audio clip under various preset code rates; according to the multiple preset code rates and the tone quality indexes corresponding to the multiple preset code rates, constructing a mapping relation between the code rates and the tone quality indexes; and based on the mapping relationship, determining a target code rate corresponding to the target sound quality index, the target code rate being used for encoding the target audio clip. According to the technical scheme provided by the invention, the audio coding efficiency
