  <p>If you don't have 18 minutes to spend, the specific answer to your question is that basically you cannot capture well the human voice when a mic is more than 3 feet away.  Even if you use a high-quality mic and a high-quality pre-amp, the quality of your audio will drop precipitously as you break the 3-foot rule.  (There are exceptions such as professional singers and actors hitting PZM stage mics, but even that is not great.)  </p>
  
  <p>If you place mics around the room in such a way that nobody has to throw their voice more than 3 feet to reach a microphone, then you might have a solution.  But that might require 20-40 microphones, and an audio system capable of recording 20-40 inputs simultaneously.  Impractical.</p>
  
  <p>Alternatively, you could have 3 mics, one for each zone of 15-30 people, which you can rapidly run to whichever audience member is trying to speak.  When they hold the mic (at least 1-2" from their mouth and at most 3 feet away), you should get fairly good results.  That would require an audio system that can record four tracks simultaneously (one for the podium mic and 3 for the audience mics), which is very simple nowadays.</p>

Answers.Text: Appreciate your input so much, and pointing to a good source. I guess I am looking for omnidirectional mic that I can place it in the middle of the audience on a stand and run through the audio board then connect to the camera.

Body: <p>What is the best way to record/capture audience audio when questions asked or interacted with the presenter without passing secondary mic hand to hand? </p>
  
  <p>Currently we have a presenter's mic that is going through audio board and on camera mic that captures general audience audio. But it creates a bad audio as camera is placed at the back at the room. </p>
  
  <p>Has any one tried placing mics around the room to capture it? Any solutions would be greatly appreciated.</p>
