Dirac Room Acoustics Software Cracked
DIRAC is a valuable acoustics measurement tool for field and laboratory acoustics engineers, researchers and educational institutions. Users can compare the acoustics of one room with another, validate sound systems and perform scale model measurements. Based on the measurement and analysis of impulse responses, the tool supports a variety of measurement configurations.
Among room correction EQ programs, Dirac Live has garnered a reputation for being one of the most effective solutions for removing the room from interfering with the sound. It accomplishes this by correcting problems with the time-arrival in sound as well as the frequency response. Other room correction equalizers ignore the time domain, but a complete solution isn't possible without addressing the time domain since latent arrivals from acoustic reflections are apart of what colors the frequency response in the first place. Let's take a brief look at how it accomplishes this, and some of the other neat features that comprise the Dirac Live package. What are the characteristics that determine the sound quality of an audio system? This is a question that for too long has been shrouded in mysticism as if there were some ephemeral magic that touched some systems and not others.
But, the truth is this question can be approached objectively, and indeed that is what Dr. Floyd Toole has been doing with over a lifetime of scientific research. The results of his research is presented in a clear, concise third edition of his book 'Sound Reproduction,' which makes for an enlightening read for neophyte audio enthusiasts and long-time audiophiles alike. Dealing with acoustics in small rooms is no trivial matter. The quest for the “perfect” room all depends on your expectations, why you are listening (business or pleasure), what program you are listening to, and the condition of the ears you are listening through.
This article focuses on the topic of early reflections in small room acoustics and how to deal with them based on listening preferences and the accuracy of your loudspeakers. The portions of side walls responsible for first lateral reflections are specified as “optional areas: absorb, diffuse, reflect.” It is a decision to be made by the customer and/or the installer. The problem with the small rooms we listen in is that they so often present us with offensive bass booms, and the bass is different at different seating locations.
The traditional solutions for taming room resonances have relied on low-frequency absorption (a.k.a. Bass traps), system layout, and manipulating room dimensions. In homes these may or may not be practical.
So my team and I investigated alternative solutions, leading to multiple subwoofer strategies and a sophisticated DSP process called Sound Field Management (SFM). This article describes the evolution of these methods, that can replace or supplement bass traps in some situations. Have you ever watched a bombastic movie in a theater with a heavy-duty bass system and felt as battered as the film's hero afterward? Ever wondered how a kick drum sound could cause that 'chest punch' sensation? Did you know that at a low enough frequency, high-amplitude sound may even be able to breath for you?

In this article we look at how bass is felt rather than heard, and, after reviewing some of the research that has been done in this area, we investigate the points at which low frequencies go beyond sound and become a tactile sensation in an experiment of our own with willing volunteers.
We caution readers NOT to try these experiments at home. For a long time, conventional wisdom has treated large and small room acoustics as one in the same. But there are fundamental differences and objectives between the two and thus they should be handled differently accordingly. Small rooms are dominated by room modes at low frequencies which needs to be addressed either with passive room treatments or a multi-subwoofer approach.
It has been shown that early reflections can be beneficial for perceiving ambiance and spatial cues in the music. This article and accompanying YouTube video discusses these topics in more depth and gives recommendations for consideration of sound reproduction in small room acoustics. Early reflections may or may not be major problems in home theaters. Addressing them through the use of heavy absorption should be pursued with caution and recent research indicates it may not be needed at all for lateral reflections. I believe the issue of early reflections and their relative merits (or lack thereof) in any home theater should never be ignored.
This article opens a dialog on how to best deal with them and how they differ from large listening spaces. Our recently added YouTube Video gives great advice on how to treat the acoustics of your theater room and also discusses the benefits of early reflections based on Dr. Floyd Toole's pioneering research. Since the dawn of the HiFi age, audiophiles have loved to tweak the sound of their audio systems.

Some do it with cables, while others employ more aggressive measures like bass and treble controls. As time progressed, our technologies advanced and we've come up with more sophisticated tone controls such as Graphic and Parametric Equalizers to offer more finely tuned adjustments.
A/V receiver manufacturers and companies such as Audyssey and Dirac have also developed their own EQ systems that measure your room response with a microphone to further tune your system. But are these auto setup and EQ systems to be trusted? Are they really useful in helping setup and fine tune your home theater system? Watch our Youtube video on this topic and please share your experiences on our forum. While we generally recommend the subwoofer crawl to help find the best spot to place a single subwoofer, there's no denying that a single subwoofer can't provide smooth response over a wide seating area. While multiple subwoofers can help deal with this issue, there aren't many guidelines floating around on how to make the most of them.

Fortunately, Todd Welti of Harman has taken the time to share his research on the matter, including simulation results for a wide range of rooms, to help you find the best locations for your subs. Eilex's PRISM EQ isn't your run of the mill room correction system. In fact, the folks at Eilex note that it's not a room correction system at all. Instead, PRISM is designed to correct the acoustic power volume density your speakers. To accomplish this, PRISM takes a series of near field measurements, and applies VIR (variable-resolution impulse response) filters. To learn more about the system, we had a chat with Eilex's own Yoshi Asahi.

Continuing our investigation of the various room correction (aka Room EQ) products on the market, we had a chat with Anthem's Nick Platsis and Dr. Peter Schuck who were kind enough to answer our questions. Anthem's Room Correction or ARC, is found exclusively in Anthem's MRX receivers and their AVM and D2 series Preamp processors. How does ARC work?
Why does Anthem limit room correction to 5 kHz? Read the article to find out. Updated on 10/08/14 with more detailed Q&A pertaining to bass management and EQ functionality.
