Module \module{aifc} defines the following function:
\begin{funcdesc}{open}{file, mode}
\begin{funcdesc}{open}{file\optional{, mode}}
Open an AIFF or AIFF-C file and return an object instance with
methods that are described below. The argument file is either a
string naming a file or a file object. The mode is either the string
\code{'r'} when the file must be opened for reading, or \code{'w'}
when the file must be opened for writing. When used for writing, the
file object should be seekable, unless you know ahead of time how many
samples you are going to write in total and use
\method{writeframesraw()} and \method{setnframes()}.

string naming a file or a file object. \var{mode} must be \code{'r'}
or \code{'rb'} when the file must be opened for reading, or \code{'w'}

\code{\var{file}.mode} is used if it exists, otherwise \code{'rb'} is
used. When used for writing, the file object should be seekable,
