What we do (make your audio sound great) isn’t seen, it’s heard—around the world and around the clock. Great audio knows no limits on time or geography, because it’s everywhere, all the time. When audio is done right, it’s part of the environment. The ambiance. The total experience.

It used to be that a technical professional had to be in the room to operate the AV equipment for every conference call. We’ve made it our mission to change that by creating smart equipment that makes system installation, operation, and management incredibly easy. Oh, and it has to sound great. If it doesn’t sound great, we’ve failed you. This is how we do audio at the most basic level.

It’s a thankless job, though, being in the audio business. But we do it because we love it. If you scratch the surface of our engineering team, down where the passion is, you’ll understand that we live and breathe audio. We understand why it’s important to the world, to every environment, and to every human on the planet. We hear you, and we want to help your clients be heard, too.

W e l i v e & b r e a t h e a u d i o

We break audio down into two different categories: Everyday and Enterprise. Our products fit into those categories and we’ll be talking about them in terms of application and process instead of just function and features. We’re taking things up a notch and digging a little deeper.

2 Bread and Butter DSP

Everyday audio is easy in and easy out. It’s audio that meets the simple, everyday needs of end users by providing professional audio at an affordable price.

Every audio installation needs a certain basic DSP toolbox regardless of the system size or purpose. It used to be that if an installation required a little more or less than what was offered in the toolbox, the end user either compromised on what they wanted, or overpaid to get the system they needed. No more!

How We Do Audio

Say your client needs a networked conferencing solution for two conference rooms that connect to Lync®. They also want the conference rooms to connect with each other.

*Just to clarify, that would be turning an Everyday audio system into an Enterprise audio system. Isn’t scalability great?†Totally false. Except the application-specific and fixed I/O parts. Those are true.

We believe in creating audio solutions that give end users everything they need, and nothing they don’t, without having to pay a premium.

Enter custom-built DSP systems to fit the audio environment and customer need. We’ve also built our systems to be easily expandable with other Biamp equipment, and compatible with third-party equipment and controls. We work hard to make products you can install with pride. Products that are relevant across environments, offering smart small- to medium-sized solutions.

That’s the exact solution to meet the exact daily-use needs of the client. If they later decide to install a facility-wide audio system using AVB, the necessary number of Tesira and TesiraFORTÉ AVB CI servers can be purchased as needed to expand the existing system. There wouldn't be any do-overs, just add-tos.*

The basic DSP toolbox is extremely important. Customizing it to fit is where the magic happens. Unless we’re talking about TesiraFORTÉ, of course, which are fixed I/O devices with application-specific powers such as flying, communicating telepathically with animals, and time travel.†

You’ll need one TesiraFORTÉ AVB CI server for each room. That’s it. The TesiraFORTÉ AVB CI can directly connect with Lync (or other soft codec applications) via its USB port, in addition to providing general high quality

audio for the room. Using AVB as its networking protocol, the TesiraFORTÉ AVB CI servers can seamlessly communicate with each other.

Nex ia®

We’ve referred to Nexia as our basic DSP, but that doesn’t mean it’s not robust and able to take on complex applications. Its processing capability makes for a very powerful system that can do everything for a single room: video- and teleconferencing, speaker processing, and multimedia presentation. A “basic” DSP, as far as Biamp is concerned, still comes packed with a full set of sophisticated audio design tools.

Aud ia®

As an Everyday audio solution, Audia gets you customizable analog hardware that we configure for you in the factory, and that you can easily change later in the field. That’s one of the best things about it. You can choose exactly how many channels in or out, and add telephony, too. Do you need POTS or VoIP? You can use both! The ability to adapt and customize audio distribution as needed is important to your clients, which means it’s important to you, which is why it’s important to us.

Tes iraFORTETesiraFORTÉ merges all the classic functionality of Nexia to the power of the Tesira platform by using AVB. This great set of tools comes in four different models with optional AVB networking, and optimized for specific business applications with fixed I/O configurations. TesiraFORTÉ speaks to the heart of our Everyday audio promise: giving end users everything they need, and nothing they don’t.

3Starship Audio

So, what qualifies as an Enterprise audio system? To us, Enterprise means

it’s not just a “big” system (i.e. lots of inputs and outputs), it means the

system is comprised of many different applications like conferencing, BGM,

paging, general audio, lecture capture, mix-minus, and court recording.

Enterprise means all of those applications (or some combination) on one platform with the capability

to integrate with other products and systems to create a single, cohesive,

networked system. That’s Enterprise (or Starship, as we like to call it) audio.

An Enterprise network can consist of more than just a robust audio system. It can include any system that runs on a network: printers, security system, manufacturing equipment, even the sprinkler system. All these mini systems that would have been handled separately, are now running on one network, and coming back to one centralized point (although there may be many devices at that point). Our equipment can be a part of that one system that rules them all.

All the systems on an Enterprise network don’t have to run on the same protocol in order to communicate and integrate with one another. With that said, the design of a DSP is fundamentally tied to the protocol it runs on. If the DSP only runs on a third-party proprietary protocol, then it will only be able to communicate with equipment that’s compatible with that protocol. Should that protocol be open standard or third-party proprietary? AVB or CobraNet®? Should we use a Dante® card? What combination of features will give integrators the best price-performance ratio? These are the questions that keep us up at night. So, we decided to program it all to be possible, and leave it up to the customer to decide what they want and need.

Bored with Using the Same Set of Processing Items When

Programming Tesira Inputs?

If you select a group of processing objects and add them to your Processing Library as a set, you will get a new item representing that group of objects. Drag it into your design and voila!, you just found a new way to save yourself some time. This method can be used as an alternative to custom blocks.

THE SITUATION

THE SOLUT ION

You have a healthcare client who’s looking to completely revamp the audio distribution and overhead paging and life safety system throughout their multi-campus facility, without interfering with the current Nurse Call system.

Here’s an Enterprise application:

much more easily with Tesira SERVER or SERVER-IO to receive direct BGM and general audio signals over CobraNet, instead of tying up limited CobraNet channels by going through the Vocia world.*

*Vocia 1.6 also integrates with Audia for this same purpose!

Tes iraFORTE

TesiraFORTÉ enhances the Tesira platform by offering four different models with optional AVB networking. Each model has a fixed I/O configuration that has been optimized for specific business applications. Equipped with a robust toolbox designed with Enterprise systems in mind, TesiraFORTÉ offers multiple combinations of inputs and outputs, and 8 channels of USB audio. TesiraFORTÉ can serve as the heart of your audio network or help you re-imagine your existing Tesira system. The choice is yours.

Voc ia®

A little different from the audio focus of our other Biamp products, Vocia focuses very specifically on professional-grade critical paging, life safety and voice evacuation. These functions are so important that they need a very focused system that specifically addresses them. With Vocia, the intelligence of the system is in the endpoints—the desk or wall paging station devices, in this case. This decentralized architecture distributes processing and page routing across the network, and eliminates the potential for a single point of system failure.

Tes ira®

Tesira is really our flagship DSP, and we couldn’t be more proud of it. The Tesira platform takes our legacy for customizable, configurable, medium-scale platforms and extends it to the large, extra large, and super-scale platforms. By using AVB, its networking capabilities are easily among the most flexible, scalable, and affordable on the market. There’s just so much you can do with Tesira:

• Partition an audio system into zones• Take advantage of the configuration engine (the intelligence marrying your design to a physical system)

• Customize the amount of DSP power in a single Tesira SERVER chassis

4 Audio Tech Deep Dive

We’ll just come right out and say it: we’re geeks!

We get extraordinarily excited when debating the benefits of floating-point and fixed-point analog to digital conversion. Our pulses race when we think about how to compile a software program that runs two and a half seconds faster. We tear up a little when we hear a customer say, “Huh, that’s clever,” when working with our products. So, if you’ll allow us, we’d like to tell you about some of the things we’ve come up with, and why we think they’re super cool.

How We Do Technology

5Processing Technologies

The core technology in the processing of digital media has grown and evolved

over the years. We are proud to have been a part of this. We embrace a

blend of well-known best practices and innovative, cutting edge techniques to

bring a rich and powerful set of tools to all of our customers.


25

State processingA design file contains processing blocks. Many of these blocks have parameters that are set during commissioning and then those parameters sit in that state for a long time. Or maybe they are tied to end user control for manual changes. These are things like levels, mutes, and router selections.

Dynamic ProcessingWe have many processing blocks that have dynamic individual parameters. These parameters are set by the system designer, and will stay in that state, or change on their own if certain specific criteria are met. Good examples of dynamic processing are found in automixers, compressors, and limiters.

Adaptive ProcessingSo, what is the next evolution in smart processing technology? Well, how about processing that “listens” to a room and has an understanding of the room’s characteristics at all times? There would also have to be processing blocks that could use that model of the room to maintain and dial in the precise performance of the processing parameters in response. And, just for kicks, it could do all that constantly, and to many different parameters simultaneously.

An example of adaptive processing is Automatic Gain Control (AGC). A microphone level is set. If the person speaking into that microphone is below a certain threshold of input level, gain will be added automatically to bring the audio up to the specified level. If the person speaking is louder than a certain threshold, the microphone signal is turned down accordingly.

6Acoustic Echo Cancellation

We never stop working on the technology behind our processing, and

refining our AEC is of particular interest to us. Of all the technologies available that enhance audio and make it more

intelligible, AEC is the fundamental component.

These days, the relative ease with which we engage with AEC can lead the world to believe that it’s easy. A given. Even trivial. We use the speakerphone on our mobile phones, or have web conferences over Lync®, GoToMeeting®, and Google Hangouts®. But the truth is, the process of acoustic echo cancellation is quite complex,

and the difference between ordinary AEC, good AEC, and great AEC is remarkable.

The less you notice the acoustic echo, the better the AEC is working. If you notice the echo, then you have a problem. When you’re conferencing over a system with great AEC it leaves you feeling that the conference

was effortless from a communication point of view. You don’t realize how hard the AEC was working for you. If it does its job really well, you’ll never know it was there. That’s great AEC. That’s Biamp AEC.

7 PARTITIONS

Over the years, you’ve shared stories with us about the inconvenience of having to bring an entire Enterprise system online at the same time, instead of being able to bring different sections online as they’re completed. That leads to system down time, which your customers may only allow after business hours, which means late nights and long hours for you.



30

We are very happy to have put an end to all that. With the partitions in Tesira, we created a tool that makes it easier to build in phases, and perform upgrades and maintenance.

The software partitions in Tesira are software-only boundaries that can be used to separate parts of a system file. Elements can be grouped by function, specific location, or even a mix of groupings. Regardless of how the partitions are divided, they can go on- and offline independently of each other.

CONVENTION CENTER

TRADE SHOW HALL

LOBBY

CONFERENCE ROOM A

CONFERENCE ROOM B

Even if the whole system is in one configuration file, a single partition can be brought offline and changed. It can then be compiled again without the other partitions being affected. And when the new file uploads into the system, the other partitions never even have to stop running.

Developing partitions made us happier than getting control of Australia in a game of Risk®. (You can’t win Risk without Australia. You just can’t.)

How to Set Proper Input Gain

To establish proper gain structure, your first concern should be input gain. Each system input provides adjustable Gain In or Trim Level, with an associated Peak indicator.

[1] For best performance, increase the gain on a given input until the Peak indicator just begins to flash on normal signal content. The Peak indicator first comes on with 6dB of headroom remaining (before clipping occurs).

[2] To provide additional headroom (that is, allowing for occasional louder input signals), we recommend that the gain then be reduced by 12dB (two 6dB decrements).*You’ll find more helpful information like this on Cornerstone at support.biamp.com

8REDUNDANCY REDUNDANCY

When Tesira was released, we created two different server types. One that

could handle a lot of analog input and output (SERVER-IO) and one that was

meant for processing centralization with lots of expanders (SERVER). But we know that centralizing processing means that people might be worried

about having too many virtual eggs in one virtual basket. So, we recognized

the need for basket insurance. While we know that one of our SERVER’s failing is

extremely unlikely,* we also know that peace of mind is worth a lot.

*No really. We even wrote a blog post about it: “Leading Causes of Biamp Equipment Failure.” Want to know the leading (non-user) cause? Lightning strikes and other power surges. 33

Now you can deploy a redundant pair, or even multiple redundant pairs of servers, and give your customers that added level of comfort. In order to make the system work the way you need it to, we made the redundant pair a true pair. Meaning the secondary SERVER knows it

needs to update itself with every change the primary SERVER makes, and it does. This way, we ensure that if a failover occurred, the sound system would behave and sound appropriately according to the last update to the primary SERVER.

Furthermore, if the secondary has to take over the system, when the primary comes back it knows that it isn’t in charge of the system anymore, and may not be up-to-date anymore. So, it reads all the changes since it was last running, and then acts as the secondary. Brilliant!

VoIP BasicsHere’s a simple overview diagram summarizing steps involved in a VoIP call:

[1] The voice signal is first encoded into a known compressed audio format, packetized in a real-time-protocol and then transmitted over the network.[2] A VoIP protocol takes care of managing the communication session.[3] On the receiving side, data is extracted from packets and the signal is decoded back to analog audio. Success of this process is obviously sensitive to delay and packet loss.

9Protocol Bridging

We rolled out a new networking card for the Tesira SERVER and SERVER-IO. It’s

the DAN-1 Dante interface card. With this new card, a Tesira system can have

input and output interfacing with Dante-based audio networks and equipment

outside of the Tesira network.

Translation: Systems that use a Dante networking protocol can now benefit

from all the power of Tesira processing.

You can put a DAN-1 in a SERVER or a SERVER-IO. A SERVER always has an AVB card in it, which means you can now have one chassis interface between an AVB network and a Dante network. Cool? You bet. But here comes cooler:

You can also put a DAN-1 card in a SERVER-IO along with an AVB-1 card, and (drumroll, please) you can even put an SCM-1 CobraNet card in that same SERVER-IO! Go ahead and read that again–we’ll wait. With Tesira, you can have a single chassis that interfaces with AVB, CobraNet, and Dante. This digital networking protocol bridge just added two lanes in each direction. Road trip, anyone?

10 Tesira and Vocia Coming Together

A preoccupation for us since Tesira was released has been how to make it integrate better with Vocia. Some of our customers have crafted ways of doing it in their installs, but we wanted to create something more direct for you. With the Vocia 1.6 firmware update, Vocia amplifiers will now be able to receive unicast CobraNet bundles from Tesira or Audia servers. That means your customers’ BGM audio channels can be sent from Tesira or Audia directly into existing Vocia amplifiers via CobraNet channels, and out through the existing speaker system.


38

Before Vocia 1.6, the BGM signals took over entire CobraNet bundles in the Vocia world, which left fewer available channels for emergency paging–the priority function of the system. The beauty of this release is that because the BGM now flows through the Tesira or Audia servers, the intelligence inherent in the 1.6 release enables Vocia to override the incoming BGM signals to prioritize the paging messages without having to operate on fewer channels.

The Vocia VI-8 increases the interoperability with Tesira and Audia by allowing paging audio inputs (either analog audio or CobraNet from Tesira or Audia) to be routed to any assigned page code within a Vocia world. You would use this to interface with existing non-Vocia paging stations (either permanently or during cutover), with fireman’s mics or integrated voice evacuation modules, and interfacing with standard sound reinforcement systems. Here’s an example: If you want to send a facility-wide broadcast from an auditorium using Audia or Tesira, you can take over the paging system and send your page throughout the entire Vocia “world.” It will override everything except priority emergency pages.

11 Configuration Engine

When we launched Audia in 2001, we developed a software compiler to go with it. But it was always a lot more than just a compiler. We didn’t make a big enough deal about it back then, so we’d like to retroactively make a big deal about it now.


42

A traditional software compiler takes code that’s written in a human-readable format such as a programming language like C, C++, Fortran or Pascal, and converts it into machine code. Machine code contains all the commands that the actual processing chips read, and sets all of the ones and zeroes to make the program work. That is what a compiler does at its most basic.

In the case of a visual programming environment like Audia or Tesira software, our compiler is taking visual representations of a program and turning that into machine code. So, everything about an input block, for example, needs to be turned into machine code. The number of inputs, what those inputs are “wired” to inside the design file, and what physical inputs are actually being assigned to that block, all needs to be converted into machine code. Every single block. No matter how big the file. It’s kind of a big job, and it has to be perfect.

In computer time, that’s a lot of work and a lot of computation cycles. But when we rolled out our compiler in Audia, we were proud because all that manual programming was no longer necessary. The compiler quickly did all the hard work. It also setup and configured CobraNet connections for the system.

When we were developing Tesira, we asked the compiler to do a lot more. We always knew that our compiler was capable of great things, and we wanted to realize that potential in Tesira. That’s why we call it our “Configuration Engine.”

What does it do? It does all of the things that Audia did, and then some. For example, anytime audio needs to move from one piece of Tesira gear to another, AVB streams are set-up to contain any number of channels within the 420 x 420 channel count, connect listeners and talkers, manage both kinds of devices, and ensure all the right lines of audio are going to the right place. Automatically. The system designer never even needs to deal with it.

The configuration engine also computes the most efficient scenario of hardware that can operate the design file, and tells you exactly what Biamp gear is needed. By “most efficient,” we mean “least expensive.” Yes, the configuration engine will give you the most affordable system that can do what your design is built to do. We know, pretty mind-blowing.

The configuration engine also keeps track of your partitions and knows what changes have occurred. If you’ve changed a few partitions, but not all of them, and you hit the “Compile All” button, the configuration engine will only compile the partitions that changed, dramatically cutting the compile time.

In addition, the configuration engine takes responsibility for only taking down changed partitions when you send an updated file back into a system that is running.
