Product Development: PD01 - Time to Market: What Can You Do about It?

Scott Leslie, PD Squared - Irvine, CA USA

Time to Market may be the most important feature in a product today. Product lifecycles and windows of opportunity are shrinking. Most product companies miss their time to market needs because they don't make major changes to their development strategy and process. In this Product Development session, the presenter will lead a discussion on the nine causes of late to market projects and how to leverage best practices, inside and outside resources, build vs buy, and development technologies to bring your product to market on time!


Wednesday, October 17, 10:45 am — 12:15 pm (1E21)

Recording & Production: RP01 - Microphones—Can You Hear the Specs? A Master Class

Helmut Wittek, SCHOEPS Mikrofone GmbH - Karlsruhe, Germany
Eddy Bøgh Brixen, EBB-consult - Smørum, Denmark; DPA Microphones - Allerød, Denmark
David Josephson, Josephson Engineering, Inc. - Santa Cruz, CA, USA

There are numerous microphones available to the audio engineer. It's not easy to compare them on a reliable basis, often the choice of the model is made on the basis of experience or perhaps just habits—or just because it looks nice. Nevertheless, there is valuable information in the microphone specifications. This master class held by well-known microphone experts of leading microphone manufacturers demystifies the most important microphone specs and provides the attendees with up-to-date information on how these specs are obtained and can be interpreted. Furthermore, many practical audio demonstrations are given in order to help everyone to understood how the numbers relate to the perceived sound.

Product Development: PD02 - Power Amplification for High Resolution Audio

John Dawson, Jade Electronics Ltd - Cambridge, UK

Driving modern passive loudspeakers to realistic levels without audible distortion can be surprisingly demanding—more so when the source is high resolution audio. And, although the peak power levels are much lower, achieving full dynamic range with headphones can also present tricky design problems. This tutorial reviews the various types of linear amplifier—particularly classes A, AB, B, D, G and H—and examines some of the trade-offs involved in designing and implementing some recent commercial designs for both speakers and headphones. A number of the author's measurements of real products—not all of them good—will be shown.

Wednesday, October 17, 11:30 am — 12:00 pm (1E10)

Applications in Audio: AA01 - Vacuum Tube Electronics for Solid State Engineers

Scott Dorsey, Kludge Audio - Williamsburg, VA, USA
David Hill, Crane Song Inc. - Superior, WI, USA; Dave Hill Designs - Superior, WI, USA
David Josephson, Josephson Engineering, Inc. - Santa Cruz, CA, USA

Vacuum tube electronics is conceptually different than solid state devices, in part because the size of each stage requires minimizing the number of stages of electronics, in part because the high impedances involved almost always require the use of matching transformers. All of these changes have severe consequences for the designer in how circuits are laid out, how feedback is used, and in fundamental circuit and system design. Younger engineers who grew up with solid state theory would benefit from an understanding of the constraints on vacuum tube systems and the consequent decisions and compromises to be made in their design.


Wednesday, October 17, 2:15 pm — 3:15 pm (1E09)

Product Development: PD03 - System-Level Solutions for Active Noise Canceling Headphones

Michael Klasco, Menlo Scientific Ltd. - Richmond, CA, USA
Mark Donaldson, SoundChip - Aran-Villette, Vaud, Switzerland
Mark Noon, SoundChip - UK

Active noise canceling headphones were first commercialized over 30 years ago yet remain a challenging product to design, manufacture and quality control. Best practice design methods for high performance passive headphones are not fully adequate when developing those with an active noise cancelling feature. Physical construction from materials, earcup wall thickness and ribbing, intra-cavity sealing and mechanical integrity of glue joints, speaker driver parameters and circuit topology all contribute to an active noise cancellation headphone’s unit-to-unit performance and stability in mass production. Our talk will focus on the unique construction and performance aspects that require particular attention during the development phase, as well as the need for precision, speed and automation during end of line testing and calibration.


Wednesday, October 17, 3:30 pm — 5:45 pm (1E09)

Product Development: PD04 - Patents and Other Key Legal Topics

Linda Cole, Harvard Law School - Cambridge, MA, USA
Philipp Lengeling, RafterMarsh - Brooklyn, New York, USA
Thomas Millikan, Perkins Coie LLP - San Diego, CA, USA
Heather Rafter, RafterMarsh - Portola Valley, CA, USA
Mark Rifkin, Wolf Haldenstein Adler Freeman & Herz LLP - New York, NY, USA
John Strawn, S Systems Inc. - Larkspur, CA, USA

This Legal Topics Supersession is two sessions in one covering the legal world of product development.

The first session covers the mechanics of patent lawsuits and what you can expect when you are involved, whether you are an owner, manager, engineer, or employee. We will cover the basic steps including: starting a lawsuit; proving a product infringes a patent, proving a patent is invalid, using experts to show infringement or invalidity; deposing experts and company personnel; asking the judge to end the case; limiting what information is available at trial, and trying a case. There will be a detour through the recently established procedures to challenge patents at the patent office rather than in court. The presentation will involve real-world experience, including our work in what was the largest audio patent case in US history (Lucent v. Microsoft) where the MP3 standard itself was on trial for patent infringement. We will present information on how often and at what stage cases settle, as most do. And we will share insights on how to win.

Our second session will provide an overview of legal considerations associated with product development and launch, including IP protection and licensing, certification and branding, privacy regulations (including GDPR), and sales, both direct and through resellers. The diverse panel of legal experts welcomes an interactive discussion around software and hardware development, data collection and storage, and industry practice and pitfalls.

Product Development: PD05 - Making Your Product Great through Adding Pre-Product Innovation Development

Scott Leslie, PD Squared - Irvine, CA USA
Jacques Spillmann, JacQuest - Los Angeles, CA, USA; PD Squared

Most products today are developed in a define, design, validate, and verify process. Because of schedules, resource availability, and traditional thinking, true innovation cannot fit into most projects. In this session the presenter will introduce the subject of pre-product innovation. This method separates innovation development from product development allowing an innovation specialist, inside or outside the organization, to create and produce concepts and pre-designs that program the direction of the product before the definition of the final product is completed or even started in some cases. Further, a method for incorporating pre-product innovation into the overall development process will be presented.

Recording & Production: RP08 - Space, Place, and Bass: Providing Modern Metal Music with an Appropriate Balance between Heaviness and Clarity

Steven Fenton, University of Huddersfield - Huddersfield, West Yorkshire, UK
Mark Mynett, University of Huddersfield - Huddersfield, UK

Distinct challenges are posed when providing the various sounds/performances of a modern metal mix with appropriate space, place, and bass. This is especially the case when down-tuning is combined with fast performance subdivisions and ensemble rhythmic synchronization.
This workshop covers intermediate-to-advanced “space, place and bass” mix principles that afford this production style an appropriate balance between heaviness and clarity, including: frequency bracketed kick and bass approaches; anti-masking mix theory (with a focus on different “designs”); dynamic EQ and multi-band compression use; series and parallel dynamics approaches; and time-based processing principles.
Mark Mynett, who lectures in Music Technology and Production at Huddersfield University, is a record producer and author of Metal Music Manual, the world’s first book on producing/engineering/mixing and mastering contemporary heavy music.


Thursday, October 18, 10:30 am — 11:45 am (1E09)

Product Development: PD06 - Loudspeaker Life Testing and Power Amplifier Requirements

Steven Hutt, Equity Sound Investments - Bloomington, IN, USA
John Dawson, Jade Electronics Ltd - Cambridge, UK
D. B. (Don) Keele, Jr., DBK Associates and Labs - Bloomington, IN, USA
Richard Little, Goertek Electronics Inc. - Santa Clara, CA, USA

Loudspeaker life testing is a critical aspect of characterizing the capacity of loudspeaker (drivers/systems) to accept input voltage. The AES2 (1984/2012) standard defines an accelerated two hour test to define a safe input level from which a device under test (DUT) can recover without permanent alteration. AES2-2012 adopted use of pink noise with a 12 dB Crest Factor that has potential to demand extreme peak capability from power amplifiers. This discussion will address the challenge of updating the life test section of AES2 with incite from industry experts. Discussion may include pre/post measurements, test duration, Crest Factor, source signal, duty cycle, mechanical vs. thermal stress, maximum useful acoustic output, power amplifier requirements, and the challenge of assigning a frequency dependent power rating to loudspeakers.

Product Development: PD07 - B Chain Sound System Product Specification: How Do We Address the Needs and Success of Our Customers?

Klas Dalbjörn, Powersoft S.P.A. - Scandicci, Italy; Dalbjorn Audio AB - Gothenburg, Sweden
Claudio Lastrucci, Powersoft S.p.a. - Scandicci (FI), Italy
Bennett Prescott, B&C Speakers SpA - Bagno a Ripoli, FI, Italy
Remi Vaucher, QSC - Costa Mesa, CA, USA

The missing part of existing and proposed loudspeaker system specifications is the lack of attention to customer requirements. The authors will lead a discussion about a future AES standard that is based on the work that Consultants, Integrators, and End Users do to successfully design, install, and operate a sound system focused on the B Chain.
The specification must include the entire B chain including processing, amplification, and acoustic components. It must have representation from the customer community as well as manufacturers. The goal is offer to the customer a method to specify the components and how they match the sound system requirements. No more marketing driven specifications and disconnected specifications of different components.

Thursday, October 18, 2:45 pm — 4:15 pm (1E09)


Product Development: PD08 - Benefitting from New Loudspeaker Standards

Wolfgang Klippel, Klippel GmbH - Dresden, Germany

This tutorial focuses on the development of new IEC standards, addressing conventional and modern measurement techniques applicable to all kinds of transducers, active and passive loudspeakers and other sound reproduction systems. The first proposed standard (IEC 60268-21) describes important acoustical measurements for evaluating the generated sound field and signal distortion. The second standard (IEC 60268-22) is dedicated to the measurement of electrical and mechanical state variables (e.g. displacement), the identification of lumped and distributed parameters (e.g. T/S) and long-term testing to assess power handling, thermal capabilities, product reliability and climate impact. The third standard (IEC 63034) addresses the particularities of micro-speakers used in mobile and other personal audio devices. The tutorial gives a deeper insight into the background, theory and practical know-how behind those standards and shows the relevance for transducer and system design.


Thursday, October 18, 3:45 pm — 4:15 pm (1E11)


Historical: H04 - Found! Lab Notes of Shure’s Ben Bauer

Michael Pettersen, Shure Inc. - Niles, IL, USA

Benjamin B. Bauer (1913-1979) held over 100 patents for acoustical/audio technology, with his first patent, at age 25, being arguably the most significant: invention of the Uniphase principle integral to the Shure Unidyne model 55 microphone. Introduced in 1939 and still manufactured today, the Shure Unidyne was the first unidirectional microphone using a single dynamic element. Today, the Uniphase principle is employed in the vast majority of directional microphones.
In September 2016, Bauer’s engineering lab notebooks dating from 1936 to 1944 were located; they had not been seen for over 50 years. The presentation provides a peek into these Bauer notebooks as he discovers and refines the Uniphase principle, as well as numerous other electro-acoustical concepts – some decades ahead of their time.
