<h2>Performance</h2>
<p>
Reads mono audio data from an external device or stream. If the command-line <a class="link" href="CommandFlags.html#FlagsMinusLowerI"><em class="citetitle">-i</em></a> flag is set, sound is read continuously from the audio input stream (e.g. <span class="emphasis"><em>stdin</em></span> or a soundfile) into an internal buffer. Any number of these opcodes can read freely from this buffer.
