-/* According to Rob Leslie (libmad author) :
- * The absolute theoretical maximum frame size is 2881 bytes: MPEG 2.5 Layer II,
- * 8000 Hz @ 160 kbps, with a padding slot. (Such a frame is unlikely, but it was
- * a useful exercise to compute all possible frame sizes.) Add to this an 8 byte
- * MAD_BUFFER_GUARD, and the minimum buffer size you should be streaming to
- * libmad in the general case is 2889 bytes.
-
- * Theoretical frame sizes for Layer III range from 24 to 1441 bytes, but there
- * is a "soft" limit imposed by the standard of 960 bytes. Nonetheless MAD can
- * decode frames of any size as long as they fit entirely in the buffer you pass,
- * not including the MAD_BUFFER_GUARD bytes.
