<A NAME="setMute(boolean)"><!-- --></A><H3>
setMute</H3>
<PRE>
public void <B>setMute</B>(boolean&nbsp;mute)</PRE>
<DL>
<DD>Mute or unmute the signal associated with this <code>GainControl</code>.

 Calling <code>setMute(true)</code> on
 an object that is already muted is ignored, as is calling
 <code>setMute(false)</code> on an object that is not currently muted.
 Going from a muted to an unmuted state doesn't effect the
 gain.<DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>mute</CODE> - Specify <CODE>true</CODE> to mute the signal, <CODE>false</CODE> to unmute the signal.</DL>

<A NAME="getMute()"><!-- --></A><H3>
getMute</H3>
<PRE>

<DL>
<DD>Get the mute state of the signal associated with this 
 <code>GainControl</code>.<DD><DL>

<A NAME="setDB(float)"><!-- --></A><H3>
setDB</H3>
<PRE>
public float <B>setDB</B>(float&nbsp;gain)</PRE>
<DL>
<DD>Set the gain in decibels.
 Setting the gain to 0.0 (the default) implies that the audio
 signal is neither amplified nor attenuated.
 Positive values amplify the audio signal and negative values attenuate
 the signal.<DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>gain</CODE> - The new gain in dB.<DT><B>Returns:</B><DD>The gain that was actually set.</DL>

<A NAME="setLevel(float)"><!-- --></A><H3>
setLevel</H3>
<PRE>
public float <B>setLevel</B>(float&nbsp;level)</PRE>
<DL>
<DD>Set the gain using a floating point scale
 with values between 0.0 and 1.0.
 0.0 is silence; 1.0 is the loudest
 useful level that this <code>GainControl</code> supports.<DD><DL>

<PRE>
public void <B>addGainChangeListener</B>(<A HREF="../../javax/media/GainChangeListener.html">GainChangeListener</A>&nbsp;listener)</PRE>
<DL>
<DD>Register for gain change update events.
 A <code>GainChangeEvent</code> is posted when the state
 of the <code>GainControl</code> changes.<DD><DL>
