sampling rate and bitrate are supported, mono and stereo are also supported. (2) for the audio spectrum, the amplitude spectrum and logarithmic spectral switching are supported. (3) The Emwin task is a low priority task, the music decoding task is a high-priority task, and the two tasks communicate through task message queues and event flags. (4) The song list dialog is modal, so the user can open this dialog box only to manipulate the dialog box, but not the main interface. Effect:Emwin-based
