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, bu

Audio Stream (proportion of redundant data): Let's take a brief look at the structure of the ADTS header: 1) The ADTS header is at the beginning of each AAC frame and is typically 7 bytes long (or 9 bytes, not seen). 2) The length of each AAC frame is fixed to 1024 sample (can be 1024*n, have not seen n>1 case). 3) Most of the information in the ADTS header is useless, only the sample rate (4bit), the number of channels (3bit) and the frame size (13bi
