Adaptive Digital Technologies is an industry-leading global provider of highly optimized, field-proven, scalable, standards-based telecom software for developers specializing in echo cancellation, high-density conferencing, speech compression, telephony, voice quality enhancement, and audio algorithms for DSPs, Arm and general-purpose processors.
Adaptive Digital Technologies Incorporated (Adaptive Digital), founded in 1994, is an industry-leading provider of voice technology. From its’ inception the mission of Adaptive Digital was to develop efficient high quality voice compression and telephony software for DSP based systems. Originally Adaptive Digital started developing INternational MARitime SATellite (INMARSAT) telephony software on Texas Instruments™ (TI) floating point processors.
Adaptive Digital’s products include High Definition acoustic echo cancellation (HD AEC™), HD stereo acoustic echo cancellation, Packet, line and Network Echo Cancellation, Voice Engine with SIP, high-density Conference engines, speech compression, telephony, and voice-quality algorithms across many platforms. Adaptive Digital’s customers include Cisco Systems Inc., Foxconn, General Dynamics, Harris, Motorola, Northrup Grumman, Ring, Sonus, Starleaf, Texas Instruments, Windstream, and Yealink.
Adaptive Digital is a member of the Texas Instruments’ Design Network, and ARM Community.
Brian M. McCarthy, Founder and President of Adaptive Digital, is the originator of the product line of voice compression, echo cancellation and telephony signaling.
Brian incorporates over twenty-eight years of experience into his DSP development and leadership responsibilities for Adaptive Digital. His professional research and product development initiated at RCA Corporation where he worked in the Voice Compression Group, followed by a research position of new voice compression techniques at Interdigital Corporation. Brian also developed and researched voice compression software for Bell Laboratories before founding Adaptive Digital.
Brian oversees the company’s current and future strategies and plans for the next generation of Adaptive Digital products.
ADAPTIVE DIGITAL TECHNOLOGIES, INCORPORATED 1994
Founded in 1994, the mission of Adaptive Digital was to develop efficient high quality voice compression and telephony software for DSP based systems. Originally Adaptive Digital started developing INternational MARitime SATellite (INMARSAT) telephony software on Texas Instruments™ (TI) floating point processors.
Immediately following the success of that project, Adaptive Digital quickly began porting other voice compression software to fixed point TI TMS320C54x™ DSP along with echo cancellation and tone detection and began integrating these software blocks into a single solution. In 1995 as a result of success with this approach, Adaptive Digital became a registered TI third party member and began porting their software to all TI TMS320C5000™, and ‘C6000™ DSP platforms. As a parallel effort, Adaptive Digital utilized several resources behind the development of their carrier class network echo-canceller. Development efforts focused on highly efficient complex and robust implementation. In 2002 Adaptive Digital Technologies’ G.168 Echo Canceller was validated as Carrier-grade at AT&T’s Voice Quality Assessment Laboratory in Middletown, New Jersey
2002 Adaptive Digital’s G.PAK framework was born. G.PAK, a scalable/configurable voice-over-packet DSP software solution, turns a DSP into an easily controlled voice-over-packet engine, was created to run on the Texas Instruments TMS320C5400 family of Digital Signal Processors.
In 2003, Adaptive Digital developed DSP ‘Chip’ Solutions, based upon G.PAK technology, a collection of DSP algorithms and Texas Instruments hardware components, which together handle signal-processing tasks for specific end equipment. In 2005 Adaptive Digital had ported it’s robust G.PAK to TI’s C55x DSPs and developed over sixty DSP software products and solutions. By 2006, G.PAK was ported to TI’s TMS320C64x family of Digital Signal Processors (DSPs).
In 2008 G.168 Plus™, a packet Echo Canceller for Voice over Internet Protocol (VoIP) Applications was developed . The G.168 Plus packet echo canceller has the unparalleled ability to handle round-trip delays of up to 512 milliseconds well beyond the ITU standard of 128 msecs. This ability to cancel echoes with exceptionally long delays, coupled with a built-in awareness and handling of packet-loss made Adaptive Digital’s G.168 Plus uniquely suitable for VoIP applications.
2009 began the porting to ARM® processors, and development of VoIP Engine™; VoIP engine is at the core of our ARM-based VoIP applications, it provides complete PCM to packet processing. VoIP Engine is a pure data processing engine. With the development of VoIP Engine came our platform based SDKs; AnVoice™ (for Android), and iPVoice™ (for iOS), and most recently LnxVoice™ (for Linux) was added to the voice engine family.
2010 was our first Multi-core porting of G.PAK on the Texas Instruments C6472 DSP.
In the years 2012, and 2013 Adaptive Digital saw the biggest leap in VoIP technology. Adaptive Digital delved into new markets (Automated Home Control, Medical) with voice solutions such as IP Intercom. We continued the porting of individual algorithms to the ARM Cortex-A series of applications processors, and expanded the base software set available in our VoIP Engine product line.
2013 Adaptive Digital began working closely with Yealink to develop a conference phone that rivals that of Polycom. In doing so, our acoustic echo cancellation (AEC) was required to meet the highest of standards in all echoic conference situations. Today we call that product HD AEC.
2014 - 2017, 2018 and Beyond
HIGH DEFINITION VOICE QUALITY SOFTWARE
Adaptive Digital’s HD AEC™ is a High Definition (HD), Multi-Mic Capable, Full-Duplex Acoustic Echo Canceller (AEC) which includes noise reduction (NR), as well as anti-howling, adaptive filtering, nonlinear processing, and double-talk detection. It operates in narrowband, (NB), wideband (WB), super-wideband (SWB) and full band (FB) frequency ranges.
Acoustic echo cancellation is an art as much as it is a science; it is not a one design fits all solution. Each echoic situation is unique; the solution usually must be fine-tuned for a specific target application. Adaptive Digital has extensive experience in the algorithm development, implementation, optimization and configuration tuning.
Adaptive Digital’s HD AEC product provides superior voice clarity and true full duplex performance under a wide set of challenging acoustic environments. It is capable of eliminating the acoustic echo in difficult conditions such as unbalanced speech levels, close speaker to mic proximity, background noise, indoor/outdoor environments, reflective room surface, double talk, and echo path changes.
Our current roadmap: Adaptive Digital’s Stereo AEC will soon be available. We are currently optimizing our HD AEC for newer platforms such as ARM’s ARMv8 architecture.
Adaptive Digital has entered the Wearables market providing voice solutions for smart applications on smaller processors such as the ARM Cortex-M4/M7™ devices.
Adaptive Digital’s algorithms run on STMicro – STM32 series of MCUs, SPEAr1310 device, Imagination Technologies’ MIPS® Processor – MIPS32® – 24 KEc®, Analog Devices SHARC, and Freescale iMX processors.
