The fields of this chunk have the following meanings:
Field descriptions
ckID The ID of this chunk. For a Form Chunk, this ID is
'FORM'.
ckSize The size of the data portion of this chunk. Note that the
data portion of a Form Chunk is divided into two parts,
These chunks are called local chunks because their chunk
IDs are local to the Form Chunk.
formType The type of audio file. For AIFF files, formType is 'AIFF'. For AIFF-C files, formType is 'AIFC'.
The local chunks can occur in any order in a sound file. As a result, your
application should be designed to get a local chunk, identify it, and then process
it without making any assumptions about what kind of chunk it is based on its
order in the Form Chunk.
