Control System and Electroacoustical Considerations for Large-Scale Loudspeaker Arrays: Past, Present & Future

May 22, 2017 2:30pm ‐ May 22, 2017 3:30pm
A timeline of live-performance system design evolution over four decades will be highlighted. In addition to a historical review of control & monitoring processes, this presentation bridges the gap from control-only networks to network digital audio, noting migration paths to beam-steerable line array elements that are now described as network endpoint devices. Tutorial also presents various loudspeaker enclosure and multi-box array topologies in use over time, as a broad-spectrum overview of technical developments taking place since the AES 6th International Conference (Sound Reinforcement, Nashville, 1988) and the AES 13th International Conference (Computer-controlled sound systems, Dallas, 1994). Each of these landmark events included content that foreshadowed the development of today’s modern high-powered loudspeaker arrays that incorporate beam-steering technology. Recently-emerging trends will be examined, and potential future developments contemplated. Of potential interest to sound reinforcement technicians and system operators, installed-system designers, rental sound service company providers, and live-sound equipment product development engineers.

Developing Novel Audio Algorithms and Plugins - Moving Quickly from Ideas to Real-time Prototypes

May 22, 2017 9:45am ‐ May 22, 2017 11:15am
High-level programming languages are frequently used by DSP and Audio Engineers for developing audio products and plugins for use in music production. These languages allow designers to rapidly create and evaluate new audio processing ideas which later are targeted for implementation in commercial audio products. In this workflow, fine-tuning the algorithm design is an important component. In this tutorial, we will use our industry knowledge to summarize the best programming practices adopted by audio companies to enable the reuse of research code directly for real-time prototypes. We will show a number of examples, tips, and tricks to minimize latency, maximize efficiency, run in real-time on a PC, and generate native VST plugins for testing and prototyping.

All You Need to Know about 3D Audio

May 21, 2017 4:00pm ‐ May 21, 2017 5:00pm
A little confused with all the new 3D formats out there? Although most 3D audio concepts already exist for decades, the interest in 3D audio has increased in recent years, with the new immersive formats for cinema or the rebirth of Virtual Reality (VR). This tutorial will present the most common 3D audio concepts, formats, and technologies, allowing you to finally understand buzzwords like Ambisonics/HOA, Binaural, HRTF/HRIR, channel-based audio, object-based audio, Dolby Atmos, Auro 3D/Auromax, among others.

Earphones, Headphones, and Headsets: Electroacoustic Design & Verification

May 21, 2017 3:30pm ‐ May 21, 2017 5:00pm
This presentation reviews basic the electroacoustic concepts of gain, sensitivity, sound fields, linear and non-linear systems, and test signals for ear-worn devices. The Insertion Gain concept is explained and free and diffuse field target responses are shown. Equivalent volume and acoustic impedance are defined. Ear simulators and test manikins appropriate for Circum-, Supra-, and Intra-aural and insert earphones are presented. The salient portions of the ANSI/ASA S3.7 and IEC 60268-4 standards are reviewed. Examples of Frequency Response, Left-Right Tracking, Insertion Gain, Distortion, and Impedance are shown. The basic concepts of Noise Canceling devices are also presented.

Quantum Acoustics, Life-Like Imaging, and the Wall-to-Wall Sweet Spot: AnySpace, Anysize, Anywhere

Oct 1, 2016 2:45pm ‐ Oct 1, 2016 3:30pm

Acoustical design is very much like music composition: both are inherently mathematical and artistic. Until the mid 2000’s, studios were trapezoidal amalgamations of architectural and acoustic geometries brimming with sonic standards of the day: saw-toothed/sloping walls, multi-planar speaker soffits, bass traps, suspended clouds, Helmholtz resonators, quadratic diffusors, etcetera, etcetera. Yet all too often imaging, intelligibility, and clarity fell prey to economy and aesthetics. Artists, producers, and engineers alike were reduced to sharing a one foot square sweet spot in even the most prestigious studio facilities. Fortunately, as change and technological evolution go hand in hand, advancements in quantum physics, materials sciences, and computational analysis have given rise to an infinite variety of design possibilities in acoustics.


On the Road with Murphy: Who's Laughing Now

Oct 1, 2016 2:00pm ‐ Oct 1, 2016 2:45pm

Stories of Humor and Irony from Touring with Mr. Murphy: How Tony Bennett's monitors got flown and other true stories of ‘gettin’ ‘er done’ on the road when the show must go on.


The Special Sauce for Mixing a Hit Record

Oct 1, 2016 1:15pm ‐ Oct 1, 2016 2:30pm

Producer Fab Dupont (Mark Ronson, Jennifer Lopez) walks through one of today’s hottest tracks with esteemed mix engineer Ryan Hewitt (Red Hot Chili Peppers, The Lumineers). Hear how the pros bring that "special sauce" to crafting a hit.


Choosing the Right Vocal Mic

Oct 1, 2016 1:00pm ‐ Oct 1, 2016 1:45pm

Selecting the best microphone for a vocalist involves gauging the singer, the environment and the material, matching a model to a stage, a voice and a musical genre, as well as tips for working with vocalists.


Easy Live Recording for Virtual Soundcheck

Oct 1, 2016 12:00pm ‐ Oct 1, 2016 12:45pm

Multi-track recording live shows has never been easier or more affordable. Modern live consoles easily record individual channels of live shows with a single cable and then play them back through the console the next day.
