| 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 | |

| 75 | <dd> |
| 76 | If <var>file</var> is a string, open the file by that name, other treat it |

| 87 | Note that it does not allow read/write WAV files. |

| 90 | A <var>mode</var> of <code>'r'</code> or <code>'rb'</code> returns a <tt class="class">Wave_read</tt> |

| 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 |
