1 """Stuff to parse AIFF-C and AIFF files.
4 both for AIFF-C files and AIFF files.
6 An AIFF-C file has the following structure.
21 An AIFF file has the string "AIFF" instead of "AIFC".
30 <version number of AIFF-C defining document> (AIFF-C only).
43 in AIFF-C files only:
56 Reading AIFF files:
69 getcomptype() -- returns compression type ('NONE' for AIFF files)
71 compression type ('not compressed' for AIFF files)
89 Writing AIFF files:
96 aiff() -- create an AIFF file (AIFF-C default)
97 aifc() -- create an AIFF-C file
131 When a file is opened with the extension '.aiff', an AIFF file is
132 written, otherwise an AIFF-C file is written. This default can be
133 changed by calling aiff() or aifc() before the first writeframes or
