  • Developing high performance VoIP software
  • Virtual relationships between parties are on the
  • Nuances in voice exchanges are a key attribute in
    productive relationship.
  • Presence management systems (enhanced IM and
    social networking tools)
  • always on demands new audio solutions.
  • Developing integrated enterprise communications
  • World class technology since 1994
  • Lead with the highest Quality of Service (QoS)
    and lowest latency available.
  • Used by the U.S. military Special Forces.
  • Ready for release into multiplayer gaming and
    always-on Enterprise VoIP conferencing
  • Including IP PBX and small platform mobility

Management Team
  • KEITH WEINER CEO and Cofounder is the passionate
    audiophile and software architect leading
    DiamondWare to build 4th generation VoIP
    solutions. His drive and entrepreneurial ambition
    have transitioned DiamondWare from a two-person
    programming shop to a world-class engineering and
    business development team with 12 people on board
    making profits. He is the author of several
    patents, a recognized audio industry leader and a
    frequently requested industry presenter.
  • ERIK LORENZEN VP, Engineering and Cofounder
    guides the development team, contributing his
    unique expertise in mixers, audio pipelines, and
    elsewhere. Erik designs the key algorithms,
    deserving direct credit for both the radical
    efficiency and good localization of Palantir's 3D
    positioning engine. Erik's engineering passion
    has led to many breakthroughs like voice
    colorization and multi-conferencing--on a server
    which supports 60 users on a 1.2GHz Pentium III.
  • JOHN WILL VP - Business Development is
    spearheading partnership development around
    Wi-Fone and Palantir, and introducing them to
    Asia. He also runs DiamondWare's military
    communications business. Prior to joining
    DiamondWare, John has worked for the U.S.
    Government engineering radar, radio, and
    communications systems. Then, as a contractor, he
    defined program requirements for a converged VoIP
  • STUART HENSHALL VP - Marketing Strategy is
    championing the vision of enterprise product
    solutions that integrate VoIP with mobility,
    real-time presence, collaboration, and learning.
    Stuart brings a broad international background to
    DiamondWare. Prior to DiamondWare he was a
    futurist and Internet strategist at GBN. Over 20
    years, he developed a track record of innovative
    consumer products as General Manager and VP Sales
    and Marketing. Stuart is also a qualified

Upfront Conclusions - POV
  • Always on access to multiple simultaneous
    conference calls is the way communications will
  • Next generation web collaboration platforms will
    all integrate with telephony and ultimately video
  • We are about to enter the age of the online
    presence spiral where presence and social
    networking will integrate with work, play and
  • All this will be available from handheld devices.

Conferences to Always-On Collaborative Listening
Industry views trapped in the change.
  • Interest and usage of collaborative conferencing
    environments is increasing.
  • Remain a compromise between face to face and a
    phone call - save money and time
  • Proliferation of new options emerging
    unfortunately most aimed at cost cutting rather
    than increasing collaboration.
  • Primarily aimed at structured / scheduled
    meetings setup seldom spur of the moment.
  • Few understand the need to integrated phone and
    mobility solutions.

Understanding Interactions Key to Emerging
Conference Opportunity
  • Sending and receiving is a rather old-fashioned
    and mechanistic view of communication. Its a
    view that, in my experience, gets organizations
    into all kinds of trouble.
  • A dialogue or a conversation occurs in (or
    emerges from) the interaction of two or more
    people, and the idea of sender and receiver is
    neither technically accurate nor, in my opinion,
    a very powerful interpretation. Nothing is
    communicated directly to another. All
    (utterances) go through the interpretation
    processes of context, meaning, significance,
    content, etc. Even apparently sensible speaking
    is frequently merely noise to its intended
    recipient. You may choose to call yourself the
    receiver but what is occurring is not a linear
  • For communication to take place on any scale
    worth talking about, it will be iterative
    generation towards a shared understanding. The
    understanding of both the originator sender?
    and others will alter as the process
  • Until we begin to give up the mechanistic
    metaphor of sending and receiving as the basic
    mode of communication, we arent going to crack
    the problems we keep confronting.
  • Michael McMaster in a posting to the Learning
    Organization email discussion group.

Traditional communication models
  • Classic ordered / tell model
  • Takes on a paternalistic or hierarchical top-down
  • Talk at rather than listen to
  • Whos listening?
  • Scanning around us is inhibited
  • Online fails to mimic social structures and
  • Currently too many deterrents to increased

Enhanced Communications Understanding
  • Our own radar provides active scanning of the
    conversations around us
  • Other conferences perturb us to listen or
  • New information sources resonate and make a
  • Order in Chaos enabled through broad listening
  • Examples RBC, IRC.

Emergent Communication Systems
  • Autopoietic models of communications are much
    closer to the messy, incomplete and complicated
    nature of communication than the traditional 1 to
    1 telephone.
  • A conference format is required that enhances
    listening and enables positioning ---
    eliminating people talking over people problems.
  • Additionally, for an online system to be
    effective it must connect multiple conferences to
    expand listening capabilities.
  • Now a system is in place that encourages new
    conversations, increases shared understanding and
    thus accelerates learning and action.

The User and the Conference
  • Enhance Listening create establish and join
    conferences of interest
  • Create a persistent set of conferences to enable
    a resonance and increase personal bandwidth for
  • Enable ownership of personal communication spaces
    or project conferences both public and private.
  • Use multi-modes --- text, voice, and application
    sharing to stimulate, capture and record progress
  • Encourages an always-on interconnected
    environment of ongoing exchanges.
  • Examples include my office, meeting rooms,
    situation rooms, the lobby, project

The classic example
  • Years ago Xerox began using receiver-based
    communication to improve continuously the work of
    its repair teams. Each worker has a
    walkie-talkie which is on all the time, carrying
    messages, just like the radio in a taxi. When a
    repair worker hears something relevant to a
    problem they are interested in, they will pay
    close attention. In this way, improvements spread
    rapidly across the group.
  • Same thing applies for IRC channels amongst
    software developers.

What must my online conferencing system do?
  • Provide 3D Sound Positioning for conference
    participants and additional presence
  • Enable broad listening so users can participate
    in multiple conferences at the same time, via
    audio, text or in combination. Always-on.
  • Be location agnostic and device adaptive to
    enable mobility and enhance always on features
    regardless of the users device.
  • Scale rapidly and easily to thousands of users
    maintaining profiles, security, and usage logs.

Changing Telephony Environment
  • The concept of telephony is changing as voice
    management and data converge new communications
    opportunities are being defined.
  • End to End Telephony Stupid Networks
  • Converging Devices - Telephone, PC, PDA, Cell
  • Enhanced Mobility local, global, virtual
  • New Feature Sets way beyond caller ID
  • Explosion of Growth and Interest News Headlines

Redefining Telephony
  • Happening all around us, individuals, homes,
    small companies and in the largest enterprises
  • Voice over Internet Protocol (VoIP), SIP
  • Wi-Fi
  • PC to PC Telephony
  • Presence and Messaging Systems
  • New handsets and headsets
  • Smart Phones
  • Intelligent PDAs

2004 -2005 Transition Point
  • Key social insights drive next level of
    technology development and value creation.
  • Begin to leave old telephony behind.
  • Acceleration of broadband deployment
  • Decreasing costs of talking
  • Advancements in software, including softphones,
    IM (instant messenger) NAT and Firewall
    transition programs
  • Changing social patterns for work and play,
    including virtual offices and work anywhere
  • The online conference becomes always on to become
    part of the work process rather than a call

Enabling Conversations Key
  • Tomorrows communications systems must
  • Enhance Conversation FLOW
  • Enable Conversation VELOCITY
  • Manage Conversation EVENTS
  • Broker Conversation SPACES
  • Seamlessly integrate with the ways in which
    people really want to use them
  • Conversations that help an organization learn
    faster are the key element for retaining
    competitive advantage.

Leadership Requirements 1
  • DiamondWare identifies key technology enablers
    and differentiators that are redefining
    communication for collaboration, presence and
  • Sound Quality Hear an audible difference as
    telephony moves to a higher quality audio
    solution. There will be a clear perception and
    audible difference between the sound of
    traditional telephony and next generation
  • 2. Spatial Positioning Since Stereo first
    introduced the sound stage we have increasingly
    brought the surround sound experience into our
    lives. Telephony has not kept up. Stereo VoIP
    technology closes the gap between the online
    conference and the physical meeting room. Future
    integration of video will further narrow the gap
    with face to face meetings.
  • 3. Presence Online presence reduces the number
    of failed connections, repetitive messages, and
    improves understanding of availability. Presence
    is only now becoming multi-modal and being
    integrated from the desktop into other devices.
  • 4. Communications Centric IM systems have
    traditionally been text centric with poor support
    for audio and video. Communications-Centric
    presence platforms are redefining how calls and
    texting work in tandem as the first step in
    enhanced collaborative communication.

Leadership Requirements 2
  • 5. Always On As call costs trend to zero,
    closing a call (hanging up at the end) resulting
    in termination may no longer make sense. In an
    open plan office chatter goes on all the time.
    In an always-on world of telephony you may
    participate in multiple concurrent conferences.
  • 6. Push to Talk Push to talk and intercoms may
    seem like a very old idea. However look at a
    money trader example and see the benefits of
    multiple lines and always on connections in a
    fast moving information environment. That
    whisper from another conference may just provide
    the answer.
  • 7. Mobility As devices combine PDAs, mobile
    phones, tablet PCs and Wi-Fi solutions are
    enabling new forms of connectivity and
    decision-making. We are preparing for a day when
    every mobile device exceeds the capabilities of
    todays PBX. Engineering reflects small devices
    and efficient solutions.

Client / Server provides controlled enterprise
solutions vs. P2P
  • Each peer adds to bandwidth
  • Audio streaming duplicated across the network
  • Adds clock time alignment complexity
  • Significant Security Issues
  • Centralized audio mixer reduces latency, enhances
  • Enables larger conferences and scales at lower

3D Positioning
  • Human ears are amazing organs. They process
    spatial cues based on phase and frequency
    response differences between the left and right.
    They use this information to determine the
    location of each sound emitter. With eyes closed,
    one can discern if a sound is in front, to one
    side, behind, or even above or below. This same
    sense works to help one focus on one particular
    sound, among many.

DiamondWare Media Stack (1)
  • APipe is DiamondWare's software component to
    manage any audio pipeline. It abstracts objects
    for source, sink, and everything in between such
    as encryption, compression, logging to disk, echo
    cancellation, jitter buffering, voice disguise,
    automatic gain controller, etc.
  • Telephony Sound ToolKit is the answer to the
    hardest problems in the client, in both streams.
    It handles the audio from mic to application, and
    from application to loudspeakers. Tele-STK was
    developed to break out of the conventional
    latency-robustness tradeoff. If the audio latency
    is too high, then the system does not provide
    business-class communications. But trading off
    sound quality for low delay is not acceptable.
  • JitPP is a dynamic jitter buffer. It performs
    three functions (1) take the packets received
    from the network out of order and unevenly
    distributed in time and turn them into an
    ordered, periodic stream (2) correct for clock
    "drift", i.e. the fact that even if the remote
    host is programmed to the same sampling rate, its
    clock rate will differ from the local clock and
    therefore it will send either too many or too few
    samples and (3) conceal lost packets.

  • DirectMixer solves a problem that is not
    apparent until one develops a softphone
    application it doesn't work unless the recording
    source is the microphone, the mic is unmuted for
    recording but muted for playback, loudspeakers
    are the digital audio destination, the
    loudspeakers are unmuted, and the volume levels
    for record and playback are appropriate. It turns
    out that this is an exceedingly difficult thing
    to achieve using the Windows API calls, but it is
    required nonetheless.
  • Mixlib is the heart of Palantir. It provides
    control mechanisms for joining/parting
    conferences and other actions which can affect
    who hears who, as well as for setting 3D
    positions, voice colorization, volume levels, and
    other real-time parameters. And it can give
    indications such as VU meter, member list in a
    conference, etc. The heart of mixlib is the
    mixing itself. This part of the code base is
    critical it must be extremely efficient because
    it executes so many times per second.
  • DDD is the algorithm and code to convert a
    monaural voice stream into a stereo sound stream
    that is perceived to be outside the listener's
    head, with a particular location vector. Like
    mixlib, this function has to be extraordinarily
    fast to run.
  • Red, Blue, Green, etc. These are the algorithms
    that colorize voices and "tag" up to eight teams
    with a unique and distinctive sound. For the same
    reasons, must be very fast to run.

  • DWSIP is DiamondWare's Session Initiation
    Protocol stack. It was developed after looking at
    several commercial and several more open-source
    SIP stacks. Although low-performance SIP stacks
    are a commodity item, there are none that require
    under 100K of memory, and none under a megabyte
    that support the latest Internet Engineering Task
    Force Request For Comment (IETF RFC) standards,
    namely RFC 3261 and SIMPLE. Reluctantly,
    DiamondWare built its own SIP stack, which saved
    on license fees and enables a truly small PDA
    voice application. Other devlopers who target
    small embedded platforms may want to consider
