0:02:19  The show begins with a big radio sound!

0:04:03   Hot weather in Southern California.  He was in Las Vegas last week in 110+ heat.  

0:04:49  Ventilation in a pre-fab booth and how to add it your recording space.

0:05:40  You need to exchange the air.  The first key after air circulation is having cool air to work with.  

0:06:58  You may need to build a “muffler” to quiet air movement.  You can buy them or build them yourself with online instructions.

0:08:22  Another trick: make the distance the air has to travel a lot longer.  Longer ductwork snaking around in the attic will quiet air movement.

0:09:06  In a small closet, you may have to get creative with convective cooling.  

0:10:30  You may have to install an A/C unit outside the house.  

0:11:32   Dan tells his tale.  He cut a hole in the ceiling of his closet and installed a “plenum.”  

0:13:37   This is why a booth in a garage is a bad idea, since there’s little cool air out there.  Also, “sound proofing” by making a booth air tight is unhealthy!  The best a basement.

0:15:34  Break

0:16:40  Radiant celestial brothers clip.  Name that movie (Grand Budapest Hotel).

0:17:00  They’re back.  

0:18:26   Q: What’s a good way to measure the “noise floor” of a personal studio.  

A: George—there is no industry standard.  He’ll listen to a voice (between -6 and -3 dB) and room tone.  He’ll then normalize to 0 dB.  He then takes the room tone and analyzes the peak level for “noise.”  He feels -55 dB is a good level.

0:20:34   Dan joins in.  Any noise below -55, -60, is much easier to remove with gating.  Don’t use reduction; it destroys audio.  Dan does a similar process.  He also looks at the frequencies of the sounds in the lower end of volume.  

0:22:46  George talks about noise gates.  

Q: Isn’t -50 kind of high?  

A: low frequency noise isn’t as loud.
