+For code 3, the TOC byte is followed by a byte encoding the number of frames in the packet, with the MSB indicating VBR. In the VBR case, the byte indicating the number of frames is followed by N-1 frame 
 lengths encoded as described below. As an additional limit, the audio duration contained
 within a packet may not exceed 120 ms.
