The fields in a Sound Data Chunk have the following meanings:
Field descriptions
'SSND'.
ckSize The size of the data portion of this chunk. This size does not
include the 8 bytes occupied by the values in the ckID and the
ckSize fields. If the data following the blockSize field
contains an odd number of bytes, a pad byte with a value of 0
is added at the end to preserve an even length for this chunk.
If there is a pad byte, it is not included in the ckSize field.
offset An offset (in bytes) to the beginning of the first sample
frame in the chunk data. Most applications do not need to use
the offset field and should set it to 0.
blockSize The size (in bytes) of the blocks to which the sound data is
aligned. This field is used in conjunction with the offset field
for aligning sound data to blocks. As with the offset field,
most applications do not need to use the blockSize field and
should set it to 0.
