Recently a customer told us that she was going to record an upcoming podcast at a conference in front of an audience and she wanted to know what is the best way to get a decent recording in a large auditorium. There are several different ways to achieve a good recording.
The best way to get good sound is to take it directly from the house sound system — eliminating the acoustic effects of the room. You’ll want to connect your recorder input cables (left and right channel) to the outputs of the sound system. Adjust the record levels so you don’t record too loud and get distortion. Remember that the output from most sound systems is at line level, not microphone level.
If it’s not possible to connect to the house sound system, you can mike the guests with your own gear (or equipment you rent). I suggest you mike each guest separately. You’ll need several microphones, mic stands, pop filters, and a mixer. Place the mike within 24 inches of each guest. Plug each mike into a separate channel on your mixer.
You can buy (or rent) a mixer at most musical instrument stores. For example, a Zoom R16 or R24 Multitrack Recorder might work nicely for your needs. You’ll have a mixer with mike inputs on the back for each guest microphone and a recorder all in one piece of equipment.
When you finish recording your podcast and need a little help cleaning it up (coughs, bloopers, long pauses, etc.) and turning it into a polished podcast, check out our audio editing and enhancing page at https://audiobag.com/audioediting.html. Meanwhile, good luck with your recording.
