The "BODY" chunk is CONSIDERABLY different than the "8SVX" form. Like all
chunks it has an ID.

    #define ID_BODY MakeID('B','O','D','Y')

Every wave has an 80 byte waveHeader, followed by its data. The waveHeader
structure is as follows:

    typedef struct {
      ULONG  WaveSize;    /* total # of BYTES in the wave (MUST be even) */
      UWORD  MidiSampNum; /* ONLY USED for Midi Dumps */
      UBYTE  LoopType,    /* ONLY USED for Midi Dumps */
      InsType;            /* Used for searching for a certain instrument */
      ULONG  Period,      /* in nanoseconds at original pitch */
      Rate,               /* # of samples per second at original pitch */
      LoopStart,          /* an offset in BYTES (from the beginning of the
                             of the wave) where the looping portion of the
                               wave begins. Set to WaveSize if no loop. */
      LoopEnd;            /* an offset in BYTES (from the beginning of the
                             of the wave) where the looping portion of the
                             wave ends. Set to WaveSize if no loop. */
      UBYTE  RootNote,    /* the Midi Note # that plays back orig. pitch */
      VelStart;           /* 0 = NO velocity effect, 128 =
                                  negative direction, 64 = positive

      UWORD VelTable[16]; /* contains 16 successive offset values
                                 in BYTES from the beginning of the wave */

     /* The ATAK and RLSE segments contain an EGPoint[] piece-wise
        linear envelope just like 8SVX. The structure of an EGPoint[]

     /* The FATK and FRLS segments contain an EGPoint[] piece-wise
        linear envelope for filtering purposes. This is included in
        the hope that future Amiga audio will incorporate a VCF
        (Voltage Controlled Filter). Until then, if you are doing any
        non-realtime digital filtering, you could store info here. */

                                = 0, then ignore this. */

       (Voltage Controlled Amp) attack portion.
       Now list each EGPoint[] for the VCA's (Voltage Controlled Amp)
       release portion.

       List EGPoints[] if any for FRLS */

   /*  Now include the user data here if there is any.Just pad it out to an

    } WaveFormInfo;

 /* END OF WAVE #1 */

 /* The waveHeader and data for the next wave would now follow. It is
    the same form as the first wave */

In assembly,  the BODY chunk looks like this:
