The Audio Engineering Society Convention

AES New York 2022

What is three days in a crowded convention hall full of audio engineers like?

It’s a completely immersive experience!

Mic Placement

Abbey Road Studio 2


The theme of this years edition of the AES convention was clear. Immersive and spatial audio is going to be the wave that propels the future of audio industry.  The range classes covered the entire work flow of how to plan, set up, record, mix, binauralize and distribute audio for the masses. Middleware like Wwise, Dolby Atmos and game engines like Unity and Unreal Engine will give audio engineers the tools they need to transition their audio tracks from stereo to an immersive aural experience.



Some of the highlights of the show floor that will be of interest include a sit-stand ready made podcast table and Ultra Low Profile Adjustable Mic Boom from Forecast and  O.C.White Co.

Magewell Capture & Combine USB Fusion is a multi-input USB video capture devise with integrated sourse switching and layout control. Offering two HDMI inputs and one USB webcam input, USB fusion can switch between sources or combine two inputs simultaneously into one output (picture-in-picture or side-by-side) for capturing into popular software via its USB 3.0 interface.

The Klover Mik 09 parabolic microphone is by far one of my favorites of the show! Engineered for the modern videographer, the KLOVER MiK 09 parabolic microphone is known as our “shotgun killer.” Attach it to the camera’s shoe mount, mount it to a light pole, attach a pistol grip, or even hang it from the ceiling, for long-range audio that’s always ready. By far the most comprehensive and effective demonstration I have ever been apart of!

This mic rig deserves an award all by it self!

Over the years I found that going to gathering like this often reward us with information that you never knew you needed or simply not aware of. Conversations with peers lead to things you simply cannot live without.

Like Krisp’s AI-powered, bi-directional Noise Cancellation eliminates background noise from your microphone and your speaker.

krispWith Krisp toggled “on,” you can rest easy knowing that your voice—and your voice only—is heard clearly. But Krisp doesn’t stop there. Sounds on the other end of the line are identified and eliminated, so there are no distractions to break your focus during that important meeting.

2022 Northwest Managers of Educational Technology Conference Summary

This April I attended the Northwest Managers of Educational Technology conference held this year in Coeur d’Alene, Idaho. Since there’s nothing quite like this group in the Southeast, it felt well worth it to me to fly across the country to enjoy a little normalcy and connect in person again with fellow A/V professionals focused on education. Of course, I can’t deny that the location for this year’s event on the shores of beautiful Lake Coeur d’Alene was an added draw. The conference was well attended (I’m guessing ~100 attendees), and exceptionally well run. NMET is a close organization with a history that spans several decades going all the way back to the beginning of the AV industry as we know it in the era of analog media.

Lake Coeur d'Alene


  • Responses to the pandemic and various school’s efforts to work toward a “new normal” 
  • The CARES Act as a catalyst for A/V classroom upgrades: UNLV launched a huge new program during COVID called RebelFlex using CARES funds that is seen as largely successful that would likely not have been possible otherwise. (Duke, along with several other top private universities such as Harvard and Princeton chose not accept CARES act funding.)
  • COVID as a driver for A/V initiatives and standardization: Many schools saw decision-making for A/V and IT-related projects shift to the provost level and higher as schools developed alternative teaching strategies such “emergency”, “HyFlex,” “hybrid,” “co-mingled,” and remote teaching as pandemic responses. In most cases timelines for implementing major A/V projects sped up significantly as well.
  • COVID as a driver for A/V standardization: Oregon State University described how COVID helped their campus standardize on an enterprise A/V strategy that centered on Kaltura, Canvas, and Zoom, and quieted demand for competing tools. Interestingly, OSU does not use a dedicated recording tool such as Panopto but instead utilizes Zoom for all recording and pushes this content to Kaltura within Canvas course sites. 
  • Faculty support models for hybrid teaching: UNLV’s RebelFlex program experimented with hiring students who were assigned to in-person classes as tech support. While overall this seemed successful, there were challenges, such as the diminishment of the need for tech support as the semester went on and faculty became familiar with the new technologies involved. Additionally it was observed that faculty members tended to morph the roles of their student help into roles resembling TAs and research assistants over time, including using these helpers as moderators for their Zoom chats.
  • Building a Networking Group like NMET: Some of the conference attendees were surprised I came all the way from North Carolina to attend the conference. “You mean the Duke?” several asked. I explained there’s nothing in the southeast comparable to NMET, an education-driven organization focused on the intersection of A/V and IT. That’s sad, but not surprising in a way, since a successful organization like NMET isn’t built overnight. NMET began holding conferences in 1979 and is the result of the hard work and passion of several generations of A/V professionals who have comprised NMET.
  • The A/V Superfriends Podcast ( Some of the members of NMET together with other A/V professionals extending beyond that group maintain a very cool podcast for A/V professionals focused on the intersection of A/V and pedagogy in higher ed. They were actually recording new episodes of the podcast live in the exhibit area. Members of this group led several interesting conference sessions focused primarily on the impact of COVID for classroom technology. Recent topics of their podcast include: 
    • Managing PO’s and supply chain issues
    • Campus support structures
    • Auto-framing and auto-tracking cameras
    • Cabling infrastructure and TIA standards
    • The intersection of A/V and IT in hiring new staff
    • AV replacement cycles–do we set arbitrary schedules of 5, 7, 10 years or tie AV refresh projects to capital projects?
    • Bootstrapping light video production switchers into classroom systems
  • AV over IP: It was argued by some that the NDI (Network Device Interface) protocol represents the wave of the future, and that we should future-proof our classrooms by purchasing NDI-capable cameras
  • Benefits and drawbacks of Zoom certification: It was discussed this may be OK as long as not mandated or exploited for commercial benefit (cross reference Tandberg)
  • “Hybrid” (instructor-driven) vs. “HyFlex” (student-centered) classrooms
  • USB as the “common language of hybrid learning spaces”
  • Elevating sound quality in the rush to add A/V infrastructure to classrooms 
  • Keeping classroom AV UI’s simple and standard even in classrooms where there is great complexity under the hood
  • ePTZ (auto-tracking) cameras: Importance of good lighting, fixed positions are better than continuous tracking
  • Making a virtual lightboard: One presenter showed how he used Procreate and a green screen in front of presenter to make a virtual lightboard 


  • Kaltura: Kaltura was one of three main sponsors of the conference. As mentioned above, Oregon State University, which was the main organizer of the conference, is a Kaltura customer. It was noted that Kaltura, unlike most other vendors, still offers an unlimited storage and bandwidth licensing tier, although it was mentioned it is “expensive.”
  • Panasonic: Panasonic was another major sponsor of the conference. Their projectors and displays were used in conference venues.
  • Elmo was showcasing its wide array of document cameras from a $200.00 USB to similarly portable wireless options starting at ~$800.00 to its flagship 4K, 12x optical zoom version designed for fixed classroom installations, the PX-30E (MSRP $3700.00). Interestingly, while WolfVision is the 500lb gorilla in the doc cam space, Elmo actually invented the document camera, and is the older company.
  • Epiphan was showcasing its well-known Pearl live encoder lineup along with its cool new device, the LiveScrypt. The LiveScrypt connects to Epiphan Cloud to add live ASR-based captions to your live production. These captions can be embedded with your live streams or sent out to monitors in the room for display for in person or hybrid events. There is a charge of $10.00/ hr to use the cloud-based ASR service in addition to the $1,500.00 cost of the device itself.
  • Alfatron had its wide range of PTZ cameras on display, ranging from a MSRP of $700.00 to $2150.00.
  • Shure had a booth showcasing equipment by Stem, a company they recently acquired. Stem offers complete solutions for outfitting conference and meeting rooms with a range of mics, including tabletop, wall, and ceiling mounted ones, together with a hub and an integrated control system for managing the individual elements.
  • Smart was demoing its latest lineup of interactive displays
  • Legrand AV showcased a wide range of products focused on physical classroom infrastructure, including displays, display mounts, projectors, PTZ cameras, speakers, device controllers, and network switches. Legrand is a large company that owns Vaddio, Chief, Da-Lite, and Middle Atlantic Products.
  • Cleardigital featured its modular display wall called Vue featuring very smooth touch surfaces and replaceable panels as well as other products such as a PTZ cam, the RL400, a portable doc cam and an all-in-one conference camera.
  • Newline Interactive was featuring its newest interactive and non-interactive displays ranging from 27” to 98”
  • AVer gave a conference session demo-ing its new autotracking PTZ camera, the TR333V2. The TR333V2 offers:
    • 30x optical zoom
    • Sophisticated pre-set configuration, including the ability to move in and out of continuous tracking and fixed position mode based on how an instructor moves in the classroom
    • 4k
    • 3G-SDI, HDMI, IP, and USB output 
    • Full or half body tracking

2019 Panopto User Conference Report

2019 WAS A FIRST for Panopto, Duke’s lecture capture provider, in that they held their User Conference near company headquarters in downtown Seattle. As this was only their third North American user conference (the previous two were held in downtown Chicago), Panopto has been slow to venture into event hosting. We don’t think that’s necessarily a bad thing as it gave the impression Panopto had been focused more on evolving their product platform when that was most needed instead of on PR. However, now that they are one of the clear leaders in the lecture capture space, it makes sense for them to begin to invest in building community through events like these. (It should be mentioned that they’ve had 5 conferences in the EU, so are a bit farther ahead there.)

Panopto 2019 User Conference Signage

This year’s conference suggests they are clearly hitting their stride. The event was well organized and well-attended, and offered a chance to meet and talk with peers from institutions all over the world as well as many of the folks on their Dev, Support, and Product teams we’ve worked with remotely but hadn’t met in person yet. The conference was hosted in an inviting venue called Block 41 that functioned as an ice house in an earlier era. The food was great, and there were nice touches that made guests feel welcome. Panopto staff seemed to always be around and available to assist or just to chat. Hats off to Panopto for putting on a great show.

Duke spoke on our use of automated recording, something we’ve been focused on from our earliest days with Panopto. Other peer sessions focused on technical elements such as integrations with LMS’s and room control systems, and there were a number of informative sessions from Panopto’s Dev team and executive leadership on product direction. One significant change CEO Eric Burns announced was a new in-browser recording tool that looks like it may be powerful and simple enough to replace certain use cases for recording via the downloadable client software. VP of Engineering Tim Sullivan gave a helpful talk on the product roadmap. Neither of those talks are publicly available, but I’m guessing Panopto will be making more public announcements about what’s ahead for them soon. We have a link to the talks that were recorded and will share that with any interested peer institutions (email

Panopto Conference Audience

The vendor selection was small but tightly focused group on core Panopto functions, such as appliances and captioning. Epiphan demoed it’s cool Pearl Mini, which offers webcasting to social media platforms in addition to simple lecture capture. It’s a higher end device with more manual controls than we need at Duke for automated recording, but impressive nonetheless. Shuttle was featuring its Panopto-certified device running Windows IoT (i.e., Windows 10 LTSB), and Matrox was showcasing its new Maevex 6020, the first true Linux appliance purpose-built for Panopto. We’ve been building and managing our own Windows appliances to work with Panopto at Duke since we started using Panopto in 2010. While we’ve worked out a lot of the kinks in the process over the years, the overhead in working with even the LTSB version of Windows is high, so the prospect of a Linux appliance is an interesting one to us.

Another nice part of the event for Duke was being able to participate on the new Internet2 NET+ Advisory Board for Panopto, which met the day before the conference in Panopto’s offices in historic Smith Tower. The Board consists of a number of schools who have been working with Panopto for some time, and is working now on developing some suggestions for Panopto as they consider their short and long-term product roadmap. Panopto’s investment in this group demonstrates their commitment to listening to customer feedback in an effort to make their product better. This type of responsiveness is something we’ve seen consistently from Panopto since we started using them in 2010, and is one of the reasons we remain satisfied with the product and services they offer.

Whitlock Convergence 2013: Sony 3LCD Laser Projector

The OIT Interactive Technology Services team attended the Whitlock Convergence Collaborative Technology Summit on October 1, 2013 where many AV/IT technology leaders were represented, including Sony. One area they were covering is in the realm of laser projectors. Their 3LCD Laser Projector, VPL-FHZ55, includes many great features which include the following:

  • 4000 lumens at 1920×1200 resolution
  • 20000h maintenance free light source
  • 360 degree tilt
  • Picture by Picture (2 inputs for side by side content)
  • Edge Blending / Color Matching (multiple projectors to create one large seamless image)



WOW Vision Collab8

Screen Shot 2013-10-04 at 10.39.16 AM

The hot AV product this year for education seems to be wireless presentation gateways.  At this week’s Whitlock Convergence show in Durham we got to take a look at several of these devices including WOW Vision’s Collab8 collaboration device.   At first glance the Collab8 looked similar to the wireless presentation products Crestron and Teq AVIT are offering, but it offers a lot more than just wireless content presentation.  The Collab8 is a collaboration device.  It supports connections from wired and wireless participants with the option of inputing a document camera, video conferencing codec or any other HDMI outputting device.  The Collab8 also supports interactive touch displays, and has built-in cloud storage, whiteboard software, and support for 3rd party apps like WebEx, Skype, and the Microsoft Office suite.

I was impressed with all the thought that went into designing this device.  It is great to see devices like this and the Christie Brio which are taking wireless presentation gateways one step further.  Overall, the functionality may be a bit more than you may need if you are just simply looking for wireless presentation gateway.  However, if you are looking for a collaboration device this could be a good fit for your space.

Convergence Technology Summit: Sony BRC Series Updates

BRC Family

Several Duke OIT Staff members were on site today at the 2013 Convergence Technology Summit.  In addition to several seminars, numerous venders were on site to showcase their wares.  I thought I would focus on one of particular interest, the Sony BRC series cameras.

For several years I have been using the BRC series with much success.  The products have a near broadcast level of quality at a reasonable price point.  Indeed, several network television productions such as Hell’s Kitchen have employed them with a good deal of success but a true broadcast grade camera it is not.  The BRC-H700 will always have a special place in my heart but I was happy when Sony announced a still higher quality version in the BRC-H900.  They also began the sunset process of the H700 by upgrading it with the Z700.  I was also excited to take note of price reductions that make them more competitive to lower end PTZ cameras that are deeply penetrating the market place.

I was able to get hands on with the H900 and Z700’s today as well as their little cousin, the BRC-Z330.  Let me run down a list of features and thoughts.  First the Z900.

Comparing the H900 to the H700, you will notice the units kept the same basic chassis and previous R2D2 form factor.  The big difference comes in the sensors and lens.  You can easily see the lens is considerably larger than the H700.  Instead of the 1/3″ 3-chip CCD design the 900 uses a 1/2″ 3-chip CMOS array.  On top of that, you could see the lens glass itself was improved, there is a considerably larger surface area on which to collect and focus light.  The lens structure also has a threaded assembly to accept lens adapters for a greater range of wide or telephoto shots.  The chassis itself accepts a large range of cards that make it an integrators dream.  There is literally not situation in which this could not be installed due to a lack of connections.  Other features are very welcome for pro video users including tally lights and various mounting systems.  While the PTZ movement is not surgical like high end products from Eagle or Vinten/Radamec it is still better than lower end PTZ’s and good enough to be considered broadcast grade in wide shot situations.  The addition of network control, that allow 112 units to be manipulated from a single control surface located anywhere is sure to leave behind the dated RS-232 standards that PTZ’s have long relied upon.  I was very impressed with this camera, the light gathering capacity of the relatively large chips and the color fidelity was very impressive.  I hope to see one in our facilities at some point.

The Z700 replaces the venerable H700.  Though it’s important to note that the H700 is not discontinued it’s obvious it’s in its twilight.  The Z700 has a very nice Zeiss lens but transitions to 1/4″ 3-chip CMOS sensors away from the 1/3″ 3-chip CCD used in the H model.  Frankly, this was disappointing and I felt a bit cheated.  The CCD vs CMOS debate is ever present.  While in general both chip designs have their pro’s and con’s, no one will ever argue that smaller sensors are better in anyway…unless you’re building a spy cam.  One could argue the 3-chip design does increase the light gathering area when multiplied out but that division happens across a spectrum.  The commitment to keeping a 3 sensor design ultimately did impress me in terms of color but I still have reservations regarding sensor size.  Other cheaper PTZ cameras on the market make use of the larger 1/3″ chips, though in a single chip design.  From what I saw I was very happy with the color the camera produced but the lack of light gathering capacity in the dark show room was an obvious weak spot that would keep this camera out of low light spaces like theaters or dim classrooms.

The last camera in this line is the BRC-Z330.  This is the value champion of the group.  It actually steps back up to a 1/3″ sensor but on a single chip design.  So the good news is you get your light gathering surface area back but reduce the color fidelity you see from the 3-chip CMOS’s in the Z330’s big brothers.  That said, the camera is at a price and feature point below many of the low cost competitors that have under cut this line for years.  This did well in the show room’s low light and had a precision of movement that while far from watch like, was acceptable for wide shot on-air movements.



Whitlock Convergence 2013: Christie Brio

Several members of OIT ITS attended the Whitlock Convergence Collaborative Technology Summit on October 1st. It turned out to be a useful event with many major players in the classroom technology space represented and showing off their newest products. Many area educational and classroom technology specialists were in attendance, and it was a good opportunity to connect with them and catch up.

Among some of the interesting new technologies we saw were several products for wireless presentation.  One speaker at the conference said that in his opinion the A/V industry has failed users in this area, and he may have a valid point. Users have a hard time understanding how in 2013 it’s still not usually possible to walk into an A/V-equipped room and with a few clicks get the contents of their computer, tablet, or even phone, to display on the room’s projector without reading through manuals and calling support staff.

One product attempting to solve this problem and that we saw at the show was the Christie Brio, which has been generating a bit of interest on campus recently.


The Christie Brio combines up to five simultaneous video and audio presentations on up to two meeting room displays. It supports up to 2560 x 1600 pixels (both input and output) and includes two dual-link DVI-D inputs, which it combines with wireless inputs to make up the 5 presentations. The DVI inputs support up to 60fps and are intended for displaying HD video sources at their native resolutions. The wireless inputs support 30fps. The Brio streams audio wirelessly or via standard jacks to feed output to the meeting room sound system, and the system contains real time whiteboard capability. There is a web administration interface for configuring source layouts and accessing meeting management information.

Christie calls the device a “node,” and multiple nodes can be combined to create a single presentation. The form factor allows the unit to be racked, but is low profile enough to be installed in a boardroom credenza.

Unfortunately the application is Windows only at this time, although the sales rep we spoke with said Mac support is actively being worked on. For the time being, an Apple TV can be integrated with the device to create Mac support, but to our thinking that didn’t seem like an optimal solution, because if you go to the trouble to set up an Apple TV, you might be able to get away without the Brio.

I saw Sharon Kaiser and Tyler Eckard of Duke University School of Medicine at the show, and they mentioned they may be demoing the Christie Brio soon, so if you’re interested, you may want to touch base with them once they’ve had a chance to take it for a spin.

More information about the Christie Brio can be found here:
