62 | ||
63 | <P> | |
64 | The <tt class="module">wave</tt> module provides a convenient interface to the WAV sound | |
65 | format. It does not support compression/decompression, but it does support | |
66 | mono/stereo. | |
67 | ||
68 | <P> | |
69 | The <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> | |
76 | If <var>file</var> is a string, open the file by that name, other treat it | |
77 | as 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 | ||

84 | <DD>Write only mode. | |
85 | </DD> | |
86 | </DL> | |
87 | Note that it does not allow read/write WAV files. | |
88 | ||
89 | <P> | |
90 | A <var>mode</var> of <code>'r'</code> or <code>'rb'</code> returns a <tt class="class">Wave_read</tt> | |
91 | object, while a <var>mode</var> of <code>'w'</code> or <code>'wb'</code> returns | |
92 | a <tt class="class">Wave_write</tt> object. If <var>mode</var> is omitted and a file-like | |
93 | object is passed as <var>file</var>, <code><var>file</var>.mode</code> is used as the | |
94 | default value for <var>mode</var> (the "<tt class="character">b</tt>" flag is still added if | |
95 | necessary). | |
