This video is a greatly expanded version of our text article How to Set Up a Room. It explains the basics of room layout and acoustic treatment, and presents practical solutions to many common problems. The focus is on home theaters, but all of the information applies equally to professional recording studios and mastering rooms. |

This video explains what MiniTraps do and shows how they are installed. Along the way many related acoustic issues are described, and you'll also see the huge improvement MiniTraps make in a typical listening room. If you use Sonar version 4 or later you can download the project file used in this video to measure the low frequency response in your own room. See the link to this file below. If you don't have Sonar go HERE to download a similar set of MP3 files that can be burned to an audio CD. |

Many people have asked how our products are made, and this video shows all. We start with a tour of the metal fabrication, then proceed to our painter, fiberglass supplier, packaging company, and finally the RealTraps factory. You'll see first hand the incredible attention to detail that goes into manufacturing all RealTraps products, and learn why we make the finest acoustic treatment available at any price. If you enjoy the sound track Men At Work, you can download an MP3 file HERE. |

Two short "slide show" videos are linked in the table at right. One features the fabulous Kelly Mittleman, the other is with RealTraps partner Doug Ferrara. These demos let you hear how truly effective the RealTraps Portable Vocal Booth is for reducing room ambience, and capturing a much more intimate sounding vocal track. The MP3 file audio-only versions are for those without a high-speed connection. In Doug's demo he explains which device you're hearing. For Kelly's demo there are four vocal takes at two distances, each with and without the Portable Vocal Booth:

This video is part of our "See and Hear" video lecture series, and more videos are planned for the future. The purpose of this series is to explain acoustic concepts in more depth than is possible with a written article alone. This video explains comb filtering, using both acoustic and electronic examples. You'll learn what causes comb filtering, why and how to avoid it, and hear how it sounds. |

This is another in our "See and Hear" video lecture series. This video explains ringing and resonance using an electronic filter to simulate the way rooms behave at low frequencies. You'll see and hear ringing and resonance, and learn how the frequency and Q of a room's modes affect its sound. |

We created this video to show that peaks and nulls occur at all frequencies in all rooms, not only those frequencies related to the room dimensions. This is very significant because it proves that all rooms need broadband bass trapping, not trapping that targets specific frequencies as many people wrongly believe. |

The conventional wisdom is you must keep listeners, microphones, and musical instruments some minimum distance away from a diffusor to avoid artifacts. So we created this brief video of an acoustic guitar and microphone only six inches away from three different surface types, as well as out in the room. The video quality is low-resolution, but the audio is 192 kbps to clearly hear the differences. Obviously, nobody will use a diffusor this close, but we wanted to amplify the effects to make them clearly audible. The microphone is an audiotechnica 4033 pointed toward the guitar, and no EQ or other effects were used. |
HOW CLOSE CAN YOU REALLY BE TO A DIFFUSOR?

If you own Sonar version 4 or later you can use this Project File to measure the low frequency response in your room. It plays one-second sine waves in 1 Hz increments from 40 to 300 Hz on Track 1. While that track plays you'll record an omnidirectional microphone onto another track, then afterward you can read the response at each frequency from the new track's Play meter. You'll probably need to resize the screen, and also change the sound card's input and output to match your own setup. Note that RealTraps now uses and recommends the fabulous ETF Windows program from Acoustisoft. It is priced very reasonably, yet does all of the important measurements required for a complete room analysis. For Mac users we suggest Fuzzmeasure. |
