  39. <h3 id="Asterisk13Function_AGC-Description">Description</h3>
  40. <p>The AGC function will apply automatic gain control to the audio on the channel that it is executed on. Using <code>rx</code> for audio received and <code>tx</code> for audio transmitted to the channel. When using this function you set a target audio level. It is primarily intended for use with analog lines, but could be useful for other channels as well. The target volume is set with a number between <code>1-32768</code>. The larger the number the louder (more gain) the channel will receive.</p>
  41. <p>Examples:</p>
  42. <p>exten =&gt; 1,1,Set(AGC(rx)=8000)</p>
  43. <p>exten =&gt; 1,2,Set(AGC(tx)=off)</p>
