Embodiment Construction
[0037] The present invention first determines the starting position of the first frame of the MP3 file, and moves the pointer to the starting position of the first frame; reads the frame header data of the current frame from the pointer and parses it to obtain the frame identifier of the current frame and the next The starting position of the frame; then read and parse the frame header data of the next frame according to the starting position of the next frame to obtain the frame identifier of the next frame; compare the frame identifiers of the two frames, if the frame identifiers of the two frames character is consistent, then analyze the sampling rate of the MP3 file according to the frame identifier, otherwise, the pointer moves down to set the number of bytes, and reads the frame header data of the current frame from the pointer again and analyzes it, according to the analysis The obtained start position of the next frame reads and analyzes the frame header data of the nex...
