<h1>01-audio-server.py - Booting the audio server.<a class="headerlink" href="#audio-server-py-booting-the-audio-server" title="Permalink to this heading">¶</a></h1>
<p>A Server object needs to be created before any other audio object.
It is the one that handles the communication with the audio and midi
drivers and also the one that keeps track of the processing chain.</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <a class="sphinx-codeautolink-a" href="../../api/alphabetical.html#module-pyo" title="pyo"><span class="nn">pyo</span></a> <span class="kn">import</span> <span class="o">*</span>

<span class="c1"># Creates a Server object with default arguments.</span>
<span class="c1"># See the manual about how to change the sampling rate, the buffer</span>
<span class="c1"># size, the number of channels or one of the other global settings.</span>

<span class="c1"># Here comes the processing chain...</span>

<span class="c1"># The Server object provides a Graphical User Interface with the</span>
<span class="c1"># gui() method. One of its purpose is to keep the program alive</span>
<span class="c1"># while computing samples over time. If the locals dictionary is</span>
<span class="c1"># given as argument, the user can continue to send commands to the</span>
<span class="c1"># python interpreter from the GUI.</span>
