14.5 <tt class="module">wave</tt> --
         Read and write WAV files</A>
</H1>

<P>


<P>
The <tt class="module">wave</tt> module provides a convenient interface to the WAV sound
format. It does not support compression/decompression, but it does support
mono/stereo.

<P>
The <tt class="module">wave</tt> module defines the following function and exception:

<P>
<dl><dt><b><a name='l2h-2879'><tt class='function'>open</tt></a></b> (<var>file</var><big>[</big><var>, mode</var><big>]</big>)
<dd>
If <var>file</var> is a string, open the file by that name, other treat it
as a seekable file-like object. <var>mode</var> can be any of
<DL>
<DT><STRONG><code>'r'</code>, <code>'rb'</code></STRONG></DT>
<DD>Read only mode.
        
</DD>
<DT><STRONG><code>'w'</code>, <code>'wb'</code></STRONG></DT>
<DD>Write only mode.
</DD>
</DL>
Note that it does not allow read/write WAV files.

<P>
A <var>mode</var> of <code>'r'</code> or <code>'rb'</code> returns a <tt class="class">Wave_read</tt>
object, while a <var>mode</var> of <code>'w'</code> or <code>'wb'</code> returns
a <tt class="class">Wave_write</tt> object.  If <var>mode</var> is omitted and a file-like 
object is passed as <var>file</var>, <code><var>file</var>.mode</code> is used as the
default value for <var>mode</var> (the "<tt class="character">b</tt>" flag is still added if 
necessary).
</dl>

<P>
<dl><dt><b><a name='l2h-2880'><tt class='function'>openfp</tt></a></b> (<var>file, mode</var>)
<dd>
A synonym for <tt class="function">open()</tt>, maintained for backwards compatibility.
</dl>

<P>
<dl><dt><b><a name='l2h-2881'><tt class='exception'>Error</tt></a></b>
<dd>
An error raised when something is impossible because it violates the
WAV specification or hits an implementation deficiency.
</dl>

<P>
