High-Flying Audio Industry

In the next few days, don't be surprised if many industry executives do not reply to your email messages. In fact, many will hardly have time to catch-up on their most urgent emails since they will be either in the middle of a busy trade show or flying across the continents and praying their flights don't get delayed or their luggage lost.


That's what happens when the audio industry is confronted with multiple consecutive events like we are facing this month. Some folks are just returning from the Prolight+Sound Guangzhou show (April 5-8) and heading straight to Las Vegas, NV, for the National Association of Broadcasters (NAB) Show (exhibits from April 13-16).


With more than 98,000 attendees from 150 countries and more than 1,700 exhibitors expected for the 2015 convention, the NAB Show is the world's largest gathering of vendors driving the future of media and entertainment. The evolution towards IP technologies, audio-networking standards being adopted for major live productions and broadcast, and the debate around ATSC 3.0 standards will be the main topics for this year's NAB convention.

The Advanced Television Systems Committee (ATSC) will be evaluating the new immersive audio proposals from three audio system proponents - Dolby Laboratories, DTS, and an alliance of Fraunhaufer, Qualcomm, and Technicolor.


The same week, many industry executives will be rushing from Vegas to Frankfurt, Germany, where the Prolight+Sound and Musikmesse shows open their doors (April 15-18). Major announcements and exciting product launches from some of the largest professional audio manufacturers are already promised with a full agenda of events for the first three days.


And if broadcast or professional audio is not your field, head for Chicago, IL, for the 2015 Audio Expo North America (AXPONA - April 24-26) at The Westin O' Hare Hotel. This will be a major event for North America's audio enthusiasts, with hundreds of exhibits, live demonstrations, and daily seminars.

The Future in High Resolution Audio


There's been a recent discussion in a LinkedIn forum that got me thinking. The conversation centers on whether high-resolution audio (HRA) is relevant given that consumers will always choose convenience over quality when faced with that choice. Is HRA a technological solution in search of a problem? Do up and coming demographics not perceive the differences between quality audio and crappy substitutes? Interesting questions.


Since the dawn of canned sound, from wax to wire and from vinyl to virtual, recorded sound has slowly moved from lower fidelity to higher. All factors being equal, any human will instinctively pick what they perceive as more enjoyable over a lesser alternative. As engineers and pro practitioners, we know that playback which best translates the emotion and joy that a performance contains will "win" over a lower quality alternative. New portable players and smartphones that provide a high-quality listening experience, along with lossless streaming from OraStream and TIDAL along with emerging standards, including WiSA, have multiplied the convenience factor already pioneered by Sonos, Olive, and others. Convenience no longer equates to low-fidelity, removing a barrier to delivering that emotional connection of which artists dream.


There once were some oft-cited studies that purported to demonstrate that "young people" and other naive listeners can't tell the difference between a highly compressed and CD version of the same song. Subjectively, we know that's jive and more recent, well constructed studies have disproved that old supposition. When a consumer is truly interested in a topic and has the time and disposable income, they tend to vote with their wallets. That immediately eliminates younger demographics, which is where ad dollars tend to be spent since they're easy marks. We as an industry need to "educate up," as my mentors are fond of saying. Some of today's young disposable listeners will become tomorrow's dedicated connoisseurs.


Now that the readily available technology for HRA delivery is out there, easy to use, and semi-affordable, younger generations are maturing with higher resolution entertainment and will be expecting it as their buying powers increase. All we have to do is enable and support their improving perceptions.


As a little green Jedi might say, "Patience... we must have." Patience to not expect overnight miracles and the foresight to know that with maturity comes discernment.

Understanding Horn

Directivity Control


By Charlie Hughes


Horns are often used in loudspeaker systems for a variety of reasons. One may be to provide increased acoustical loading to the driver attached to the horn. This helps to increase the sensitivity/efficiency. Another may be to provide some control over the radiation pattern of the driver attached to the horn. This article focuses on the directivity control aspect. It was originally published in Voice Coil, November 2010.  Read More
