/**
* Get Line In
* by Damien Di Fede.
*
* This sketch demonstrates how to use the <code>getLineIn</code> method of
* <code>Minim</code>. This method returns an <code>AudioInput</code> object.
* An <code>AudioInput</code> represents a connection to the computer's current
* record source (usually the line-in) and is used to monitor audio coming
* from an external source. There are five versions of <code>getLineIn</code>:
* <pre>
* getLineIn()
* getLineIn(int type)
* getLineIn(int type, int bufferSize)
* getLineIn(int type, int bufferSize, float sampleRate)
* getLineIn(int type, int bufferSize, float sampleRate, int bitDepth)
* </pre>
* The value you can use for <code>type</code> is either <code>Minim.MONO</code>
* or <code>Minim.STEREO</code>. <code>bufferSize</code> specifies how large
* you want the sample buffer to be, <code>sampleRate</code> specifies the
* sample rate you want to monitor at, and <code>bitDepth</code> specifies what
* bit depth you want to monitor at. <code>type</code> defaults to
<code>Minim.STEREO</code>,
* <code>bufferSize</code> defaults to 1024, <code>sampleRate</code> defaults to
* 44100, and <code>bitDepth</code> defaults to 16. If an <code>AudioInput</code>
* cannot be created with the properties you request, <code>Minim</code> will report
* an error and return <code>null</code>.
*
* When you run your sketch as an applet you will need to sign it in order to get an input.
*
* Before you exit your sketch make sure you call the <code>close</code> method
* of any <code>AudioInput</code>'s you have received from <code>getLineIn</code>.

You'd need to contact damien (who wrote minim) for minim bugs, but this
error is outside of Java (anything that we can control) and looks like a
bug in Apple's Java implementation, or that your Java installation is
somehow broken (for instance, if you installed Java 1.5 on OS X 10.6).
