Adaptive Digital’s iPVoice VoIP engine is a software package that provides all the voice processing necessary to VoIP-enable an iPhone application.

Adaptive Digital Technologies (Adaptive Digital), a dominant player in the voice software landscape for over sixteen years has made available to Apple Inc. iPhone application developers its toll-quality voice engine software with the introduction of iPVoice™ VoIP Engine.

Well established in the telecom and VoIP communities with a reputation for providing high quality digital signal processor (DSP) software, Adaptive Digital first broke into the Mobile market with the successful launch of anVoip™ a voice engine product enabling VoIP for Android development. With a solid understanding of a processors capability and limitations, and a comprehensive library of optimized algorithms Adaptive Digital was able to offer the mobile market a VoIP solution that did not excessively burden the mobile device processor. Adaptive Digital has now applied that same expertise to Apple’s iPhone and developed a VoIP voice engine that will bring true toll-quality to iPhone voice applications.

Adaptive Digital’s iPVoice VoIP Engine for iPhone is a software package that handles all the processing needed to transform PCM samples to VoIP packets and VoIP packets to PCM samples. In other words, it provides all the voice processing necessary to VoIP-enable an iPhone application.

iPVoice VoIP engine includes a complete suite of Adaptive Digital’s CPU and memory efficient fixed-point telephony, VoIP, and voice quality enhancement (VQE) algorithms that enable developers to create toll-quality next generation mobile device applications for iPhone users. iPVoice VoIP engine includes acoustic echo cancellation (AEC), AGC, G.711 with DTX, RTP, tone generation, and network optimization algorithms including packet loss concealment (PLC), and adaptive jitter buffer (AJB). Additionally features can be added such as noise reduction, SIP and a wide variety of compression algorithms including both narrowband and wideband codecs. With the wide variety of Adaptive Digital’s fielded voice software at their fingertips, developers can now deliver the highest level of quality voice enabled applications.

Adaptive Digital provides for easy implementation and flexibility through the VoIP Engine API functions. iPVoice VoIP Engine brings the same type of ease to a iPhone VoIP developer as is brought by the existing iPhone frameworks that handle other functionality. All the developer needs to do is include the iPVoice library into his or her project and make use of the VoIP Engine API functions. The API functions configure the VoIP Engine as well as handle PCM to Packet and Packet to PCM processing. The processing APIs are designed to interface with the audio I/O and IP stack, which further enhances the developers’ flexibility.

Adaptive Digital has over the years met and surpassed all of the challenges that are currently problematic in the mobile device network. Adaptive Digital has applied its voice application software expertise to the mobile digital device market. Adaptive Digital’s extensive knowledge of digital voice processing is proven by their outstanding reputation and repeat customer base.
