David Kahn of Acoustic Dimensions is part of the presenting team for an exciting event coming up on Friday, September 23 in Winnipeg Canada.  We extend a welcome to the Acoustic Dimensions network to be part of a lively discussion and demonstration of technology and its application in keeping performing arts centers relevant in meeting the growing sophistication of audience expectations.  There is no fee to be part of this forum of peers.  This topic particularly hits home as Centennial Hall, the event host, anticipates major capital improvements to renovate its facility for its 50th birthday in 2018.

If you would like to attend this meeting & demonstration please let us know.

Contact Kirsten Haas before or on September 19th; khaas@ad-ny.com 914-212-1300 x27

A limited number of complimentary concert seats are available for The Winnipeg Symphony Orchestra’s evening performance.  Please let us know how many ticket you would like when responding to this invitation.

 

TECH TOPIC | Internet Streaming

Internetstreaming101

Most of our clients have applications for streaming video of live events whether they are corporate clients, performing arts facilities, worship facilities or colleges and universities.

At its most basic, internet streaming is about taking an audio feed and a video feed, using an encoder to convert them to a format streamable over the internet, then getting that feed to a service provider who will host your videos in ways that people can easily access them. That’s the short version. The variety happens in how you capture the feed, how you convert it and what host you choose.

The first decision you will need to make is which video encoder you want to use to process your audio and video feeds.  You can select a capture card with encoding software—which typically supports a single format output (QuickTime, Microsoft Silverlight, Adobe Flash) or you can use a stand-alone encoding unit which does not require a PC.

The feed then travels via your internet connection to your streaming provider—typically a content delivery network.  A content delivery network or content distribution network (CDN) is a system of servers containing copies of data placed at various nodes of a network. The tradeoff in using a CDN or another streaming provider is usually about distance. The more hubs the provider has, the shorter the distance to get from the server to the person at their computer (or handheld).  Another popular option is Amazon’s Web Services (AWS)—which allows you to stream paying only for the loads you use.

Some hosts offer cloud-based archival storage so that you can offer content on-demand in addition to live streaming.

THIS WEEK | Design Workshop in San Diego

Acoustic Dimensions is working with Visioneering Studios and The Father’s House in Vacaville in an interactive, highly collaborative work-session over the next three days.  The design workshop is structured to take the systems from concept to documentation with budgets being developed in real-time.  As the client makes decisions, they can see the result of those decisions with input from the architect and engineers.  This approach—with all of the stakeholders at the table—allows ideas to be generated very quickly and just as quickly learn if they are viable or not.  Better yet, good ideas inspire other good ideas and the creativity not only develops the design on an accelerated schedule, but also results in systems where the client is actively involved in the process.  Day One is complete and ideas are flowing!

Frame of Reference

 We all work within some sort of frame of reference every day that is based on our personal experience.  For example, I could say that it was REALLY hot today – that it was 38 degrees outside – and depending on who I was talking to, I might get different reactions.  If your frame of reference was degrees Fahrenheit, then you’d think I was a nutcase.  But if your frame of reference was degrees Celsius, then you wouldn’t even think twice about it.  (38 degrees Celsius is equal to 102 degrees Fahrenheit) 

Whenever you work in a specific engineering field for any length of time, you adopt and function using specific jargon that outsiders don’t often understand or can relate to.  A common example in the field of acoustics is measuring background noise levels.  Without any sort of frame of reference, it’s difficult to know if NC-50 is quiet or really loud.  (It’s actually very loud for most functions and programs.)

The acoustics of any room, while very complex, can be described in various quantities of reverberation, reflections, and so forth.  If we recommend putting in a certain amount of sound absorption into a room in order to reduce reverberation, how can we know what sort of subjective improvement will be realized for the amount of money spent?  The answer is that just like a visual computer rendering of a building, we can develop and play a simulation of the acoustical characteristics of the room and compare it to the existing condition.

 The attached audio file does exactly that.  As you listen, you will hear the music switching back and forth between the simulation of the existing condition and the resulting condition based on the design recommendations.  (It is best to listen on a good pair of headphones.) This file provided a great subjective reference and allowed the client to make an easy decision – now knowing how much improvement they would get for the money spent …

 

Breaking the rules with turntables and symphonies

Nicholas Edwards had the opportunity to work this week at Birmingham Symphony Hall with Gabriel Prokofiev—the London-based composer, producer, and founder of the NONCLASSICAL record label.  The concerto, which includes Prokofiev’s Concerto for Turntables and Orchestra, is performed by the National Youth Orchestra.  Listening to them you would not know this was not a professional orchestra; conductor, Vladimir Jurowski, demanded and received the highest standards of musical performance. Even though this was just a rehearsal there was applause through the hall at the end of the performance.

Prokofiev is focused on bringing classical music to younger, more diverse audiences, introducing urban sounds into the concert hall. Nick was on hand to explain the capabilities of the hall, the acoustic differences from normal DJ club venues, and how to get the best out of the hall for this particular performance.

The performance at Symphony Hall will be on August 3rd, and the final performance will be Saturday, August 6th at Royal Albert Hall.
