WHEAT:NEWS Volume 6, No. 8

Wheatstone Sign 250w

With our guys just returning from IBC, which was a great show, and with many of our customers heading into college football season, we're kicking off our September issue of WHEAT:NEWS by highlighting some unusual places you might find IP audio useful.

Also this month, tips on gaming the system with WheatNet-IP, thoughts on listener measurement in Brazil, and clearing the air on loudness.

5 Surprising Places for IP Audio

It's getting late. Do you know where your audio network is?

BLADE TRUCK_2560Your audio network could be going places and doing things you might not be aware of, from remote sportscasts and for STLs to hanging out in malls, convention centers and auditoriums.

Modern audio networks are being used for a slew of new applications because of newer, smarter I/O units. For example, WheatNet-IP BLADE-3s combine integrated control with audio tools such as mixing and audio processing at every connection point in the network for a multitude of possible uses.

It’s almost like having a complete studio in 1RU wherever you need one.

And with AES67 now promising to interface your network to just about any audio device out there, there’s no telling where IP audio will be off to next.

Here are just a few ways you can use your WheatNet-IP BLADE-3s:

Audio in the Outfield: Quickly set up a small studio at any sports venue with routing, processing, mixing and logic controls of mics and other devices all in one rack unit. All you need is a BLADE at the press box as your audio interface into your mixing board and mics (16 mono channels) and an Internet or other link to the studio. To take advantage of 5.8 GHz unlicensed wireless IP radios as a line-of-sight link to the studio, simply add an EDGE unit. EDGE connects directly into the IP wireless radio through RJ-45 connectors, and because it’s all IP, that means you can carry audio, voice-over-IP, and data of all kinds back and forth between locations.


BLADE AS_AUDIO_SNAKEIP Audio Snake: Transport audio between the production studio and a nearby performance studio using BLADEs at each end. Carry mic and instrument feeds from the stage area to the network over CAT6, wireless or optical fiber link. Do separate mixes live using the BLADE’s 8x2 stereo mixers, or capture multitrack recordings for future mixing. No transformer splits required!


STL: Continue IP audio from the studio to the transmitter with BLADEs on both ends of an IP wireless or other STL. IP radios connect to the switch on each end, which are connected to the BLADE for managing audio and any devices hanging off the network. If the STL should lose connection, the new BLADE-3 will not only detect silence, it can trigger the startup of playback audio stored on the BLADE-3 itself.


Multi-stage venues. Place BLADE I/O units in the van, on stages or throughout the field, and connect them together over fiber and CAT6 via the network switch for audio transport between them. Great for music festivals that require real-time communication between multiple stages.


IFB. Talk to talent over your IP network. Any WheatNet-IP BLADE access unit that routes audio also can provide the IFB pathway, whether it’s on location or in the studio; simply change crosspoints to create routable IFB throughout the facility.


AoIP Tip: Gaming the System

ScreenBuilderWidgetSampler PreviewWindowIf you are doing some serious sports coverage this season, here’s a tip. You can create a map of all your sports venues through one customized Screen Builder interface for your WheatNet-IP audio network, and click between them to bring in feeds, set processing, and call up mic presets.

All you have to do is arrange faders, knobs, buttons, clocks, timers, meters, events and other widgets in a drag and drop environment. Then link widgets to hardware such as microphones, codecs, and consoles located in the network and determine what each widget does using a simple Script Wizard.

SaveDiffusionScreenBuilderMap2AgileScreenBuilderIn addition to mapping out all your sports venues for the season, Screen Builder can be used to customize the WheatNet-IP audio network for a million and one purposes.

He Who Listens, Likes

You’re going to love how BestRadio Brasil measures listenership, and we think you’ll like the studios too!

IMG 6655_v2What’s not to like about independent online station BestRadio Brasil in São Caetano do Sul, São Paulo, Brasil?

The music is eclectic, the sound is distinct, and the studio is magnificent. BestRadio Brasil is using WheatNet-IP audio routing and control with an IP-12 digital audio console, which pulls double duty for live webcasts as well as for production purposes.

“We use this studio as a hybrid studio,” says David Jill, the station’s CEO and Program Director. It’s not uncommon to have live programming going on in the studio at the same time an operator is finishing up production. The IP-12 fits the studio’s busy, multi-prong workflow because of its size and IP routing.

The IP-12 feeds four audio IP channels directly into a recording computer for 100 percent digital operation throughout. David says the all-digital operation using WheatNet-IP audio networking makes all the difference in the quality of programming, which covers a wide spectrum of music, including eurodance, pop, rock, and R&B. The proof seems to be in the numbers: BestRadio Brasil netted 47 percent of the votes in the Top 2009 Web Radio survey and continues to rank among the top online stations in the region.

Clearing the Air on Loudness

Did we hear you say, “Let’s start an audio cleanliness war?”

BoxingAirAuraX3 2560sm“I want to start an audio cleanliness war…Who is with me?”

It was music to our ears when we saw these words posted on the Facebook “I Love Broadcast Audio Processing” discussion page recently.

If only!

In many ways, we at Wheatstone have been slowly working our way toward that day when ears no longer bleed and modulation monitors look like they’re glued to 100%.

So while we’ve built into our audio processors the tools you need for both a loud and an open and clear sound on the dial, so much more can be done. Even with so many AirAura’s, VP-8’s and FM-55’s in the field, it’s time to talk about what it takes to create clean audio on the radio -- something that can be applied no matter what type of processor you use.


  1. Make sure that your source material is linear. Storage is cheap. There’s no reason to use lossy audio codecs on the air. It’s said that cleaning up your source material can have the same impact as getting a new on-air processor.
  2. Set standards. Having a set of standards in place for production is paramount for a consistent sound. When people come in and record anything at any level they want, or add equalization while others don’t, this adds up to a poor overall sound on the air.
  3. Weed out unnecessary equipment. Your on-air signal could be passing through two or three devices in the air chain that are no longer needed, but no one took the time to remove or bypass. Go over your air chain and simplify it as much as possible. The less gear the on-air signal needs to pass through, the better.
  4. Optimize STL paths. It’s not always possible to have a linear path, but when you can, do so. Also, you will get better results almost every time when you use composite over discreet AES left and right. The stereo generator in a modern audio processor is almost always better than one built into an exciter. Of course, with Wheatstone processing and the right exciter, you can have both AES and composite!
  5. Maintain your transmitter. Transmitter site maintenance is key in making sure your station sounds good. Proof of performance, while no longer required, is still a good idea. The engineer and the transmitter building should not be strangers!

Your processor can do amazing things, but only when it’s fed amazing audio and feeding a linear path. If you haven’t had time to focus on your audio plant, make yourself an early New Year’s resolution to do so!
