-For codes 2 and 3, the TOC byte is followed by the number of frames in the packet.
-For code 3, the byte indicating the number of frames is followed by N-1 frame
+For code 2, the TOC byte is followed by the length of the first frame, encoded as described below.
+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.
