62
63<P>
64The <tt class="module">wave</tt> module provides a convenient interface to the WAV sound
65format. It does not support compression/decompression, but it does support
66mono/stereo.
67
68<P>
69The <tt class="module">wave</tt> module defines the following function and exception:
70
71<P>
72<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
73 <td><nobr><b><tt id='l2h-4708' xml:id='l2h-4708' class="function">open</tt></b>(</nobr></td>
74 <td><var>file</var><big>[</big><var>, mode</var><big>]</big><var></var>)</td></tr></table></dt>
75<dd>
76If <var>file</var> is a string, open the file by that name, other treat it
77as a seekable file-like object. <var>mode</var> can be any of
78<DL>
79<DT><STRONG><code>'r'</code>, <code>'rb'</code></STRONG></DT>
80<DD>Read only mode.
81
82</DD>
83<DT><STRONG><code>'w'</code>, <code>'wb'</code></STRONG></DT>
84<DD>Write only mode.
85</DD>
86</DL>
87Note that it does not allow read/write WAV files.
88
89<P>
90A <var>mode</var> of <code>'r'</code> or <code>'rb'</code> returns a <tt class="class">Wave_read</tt>
91object, while a <var>mode</var> of <code>'w'</code> or <code>'wb'</code> returns
92a <tt class="class">Wave_write</tt> object. If <var>mode</var> is omitted and a file-like
93object is passed as <var>file</var>, <code><var>file</var>.mode</code> is used as the
94default value for <var>mode</var> (the "<tt class="character">b</tt>" flag is still added if
95necessary).
