<p>The following methods allow you to retrieve recorded audio data in
various ways.
</p>
<a name="XREF_0040audiorecorder_002fgetaudiodata"></a><dl>
<dt><a name="index-getaudiodata"></a><em><var>data</var> =</em> <strong>getaudiodata</strong> <em>(<var>recorder</var>)</em></dt>
<dt><a name="index-getaudiodata-1"></a><em><var>data</var> =</em> <strong>getaudiodata</strong> <em>(<var>recorder</var>, <var>datatype</var>)</em></dt>
<dd><p>Return recorder audio data as a matrix with values between -1.0 and 1.0
and with as many columns as there are channels in the recorder.
</p>
<p>Given the optional argument <var>datatype</var>, convert the recorded data
to the specified type, which may be one of <code>"double"</code>,
<code>"single"</code>, <code>"int16"</code>, <code>"int8"</code> or <code>"uint8"</code>.

<dt><a name="index-getplayer"></a><em><var>player</var> =</em> <strong>getplayer</strong> <em>(<var>recorder</var>)</em></dt>
<dd><p>Return an audioplayer object with data recorded by the audiorecorder object
<var>recorder</var>.

<dd><p>Play the audio recorded in <var>recorder</var> and return a corresponding
audioplayer object.
</p>
<p>If the optional argument <var>start</var> is provided, begin playing
<var>start</var> seconds in to the recording.
</p>
<p>If the optional argument <var>end</var> is provided, stop playing at
