4.18.   Recommended buffer size

   Sometimes the server from which an audio file is streamed is aware of
   transmission or coding problems resulting in interruptions in the
   audio stream. In these cases, the size of the buffer can be
   recommended by the server using this frame. If the 'embedded info

   flag' is true (1) then this indicates that an ID3 tag with the
   maximum size described in 'Buffer size' may occur in the audio
   stream. In such case the tag should reside between two MPEG [MPEG]
   frames, if the audio is MPEG encoded. If the position of the next tag
   is known, 'offset to next tag' may be used. The offset is calculated

   from the end of tag in which this frame resides to the first byte of
   the header in the next. This field may be omitted. Embedded tags are
   generally not recommended since this could render unpredictable
   behaviour from present software/hardware.

   For applications like streaming audio it might be an idea to embed
   tags into the audio stream though. If the clients connects to
   individual connections like HTTP and there is a possibility to begin
   every transmission with a tag, then this tag should include a
   'recommended buffer size' frame. If the client is connected to a

   arbitrary point in the stream, such as radio or multicast, then the
   'recommended buffer size' frame SHOULD be included in every tag.

   The 'Buffer size' should be kept to a minimum. There may only be one
   "RBUF" frame in each tag.

     <Header for 'Recommended buffer size', ID: "RBUF">
     Buffer size               $xx xx xx
     Embedded info flag        %0000000x

     Offset to next tag        $xx xx xx xx
