SATlive® Audio Measurement Tool HOME News: New Version 1.60.02 What's new? learn studio design, treatment methods and tools used. On the left is the expected response based on the rooms dimensions, on the right is a screen shot of the results from REW. There is a large margin for error here as the room is full of furniture, and there is an archway and window sills to take in to account. On comparing the two sets of results there are clear correlations between the response plot on the right and the room mode plot on the left. Most notably between 400 and 500 Hz, were there is a rise and a dip, but this is not the only correlation.
Meyer Sound The Mixing Workshop: Session 11, Gateway Church and the Meyer Sound Solution 1 Hour | English In his role as Executive Director, Technical Arts for Gateway Church, David Leuschner works to facilitate all audio, video, and lighting needs for the ministries of Gateway Church. David has worked with Meyer Sound products for a number of years and in this conversation with Meyer Sound’s Buford Jones, David brings the perspective of the end user to describe Gateway Church’s use of Meyer Sound products in Gateway's facilities and the support Meyer Sound as a company has provided throughout this relationship. David will talk about his experience using Meyer Sound products for many years, Gateway Church’s introduction to Meyer Sound, and the role Meyer Sound systems have played in helping them successfully convey their message to the Gateway congregation.

How To Set Up a Room More RealTraps Articles Straight talk about finding the ideal loudspeaker placement and listening position. "You'll get the flattest low frequency response by sitting 38 percent of the way back in the room." "This is equivalent to a bank shot in pool." With special thanks to Bill Eppler for providing the first reflection calculations, and to acoustics guru Wes Lachot. The following is from a newsgroup post where Wes explained his logic behind the 38 percent rule. FuzzMeasure FuzzMeasure Pro 3 delivers a comprehensive suite of features geared towards professionals in the acoustics, live sound, and recording industries.

Products mh acoustics’ patented Eigenmike® microphone array is composed of many professional quality microphones positioned on the surface of a rigid sphere. Eigenmike® microphone array technology is a two-step process: First the outputs of the individual microphones are combined using digital signal processing to create a set of Eigenbeams. A complete set of Eigenbeams capture the soundfield up to the spatial order of the beamformer.
Acoustics So you want to setup a studio so why worry about acoustics and what are acoustics anyway? Let me tell you a story as I heard it from the late Dean Jensen who I stayed with in the early seventies when he was the top techo in LA. --- According to Dean in the early seventies some of the engineers of The Record Plant (one of LA's top studios ) were sitting on the roof of their building after a long party. They had taken some speakers from the studio up to the roof for the party and were discussing the fact that the speakers sounded great on the roof but were pretty awful downstairs in their control room! Why??
Fletcher–Munson curves The Fletcher–Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A. Munson, and reported in a 1933 paper entitled "Loudness, its definition, measurement and calculation" in the Journal of the Acoustic Society of America. Background The first research on the topic of how the ear hears different frequencies at different levels was conducted by Fletcher and Munson in 1933. In 1937 they created the first equal-loudness curves. Until recently, it was common to see the term 'Fletcher–Munson' used to refer to equal-loudness contours generally, even though a re-determination was carried out by Robinson and Dadson in 1956, which became the basis for an ISO 226 standard.
Room EQ Wizard Tutorial - GIK Acoustics Room EQ Wizard tutorial presented by GIK Acoustics. In this video we take you through downloading, installing, and using Room EQ Wizard. You will learn how to set up your microphone and calibrate your soundcard, as well as how to take a room test measurement. You will also learn how to set up the limits and viewing ranges for the frequency response graphs and we show you how to generate a waterfall graph. Octave smoothing and overlays are shown as well. To download Room EQ Wizard, go to Then register on the Home Theater Shack forum if you haven’t already.
Dirac Dirac is a sophisticated tool to calculate a very wide range of acoustical parameters from impulse response measurements of an enclosure. Through many years of development and customer feedback, Dirac has grown to support many different applications. Due to its user friendly interface it is suitable for field measurements, but it also contains many advanced features that make it useful in a laboratory or research setting. To capture an impulse response, a stimulus signal is generated by Dirac or an external source. This stimulus signal is played in the enclosure through a sound source, and recorded through a microphone. Dirac then deconvolves the recorded response with the original stimulus to arrive at the impulse response.
AudioTools Modules Impulse Response Smaart® Tools Transfer Function STI-PA Module Pricing AudioTools includes a base set of apps in the initial purchase price, and then has a number of optional modules that you can purchase from within AudioTools at any time as in-app purchases. Speakers Go to manufacturer's links As discussed in the opening page, the car and open air are good listening environments because they have either no reverberation or a controlled reverberation field. One of the key points was the flush mounting of the car speakers. By building your speaker boxes into the wall you can tighten the bottom end of the whole system because you eliminate the reflections that emanate from the back of the speaker, hit the wall and then come back to you in and out of phase. Here the sound from each speaker comes back off the walls and creates a general mayhem of frequencies in the middle where the engineer would probably be sitting. In the open air the sound waves are passing you and never come back.
Christina Campanella Music • Sound • Unsound Composer and performer CHRISTINA CAMPANELLA works with music, sound, and performance across artistic disciplines. Her original pieces for theater, ﬁlm, and installation blend songwriting and composition with aural design, weaving found sounds, ambient textures, and a dreamy pop-rock sensibility into cinematic soundscapes and deconstructed art songs. As an actress, singer, and instrumentalist, she has brought her classical background to a constellation of innovators, including the work of multidisciplinary theater-artist Jim Findlay, composer-visual artist Joe Diebes, directors Richard Foreman, Phil Soltanoff, David Levine, Toni Dove, Mallory Catlett, and many others. Ongoing: Christina received commissioning to compose music and audio content for PARTS ARE EXTRA, a sound and cinema project co-created with filmmaker and visual artist Peter Norrman (NYSCA Film, Media, New Technologies award, 2011).
