Spirit DSP, a voice and video over IP engines provider, today announced a significant upgrade to its TeamSpirit cross-platform voice and video engines and a set of sophisticated software development kits (SDKs) for service providers, software application developers, and OEMs/ODMs to launch high-definition voice and video calling applications and services across all popular desktop and mobile devices.

The new versions of Spirit's TeamSpirit Voice & Video Engine Mobile, TeamSpirit Conferencing Server Engine, and TeamSpirit Voice & Video Engine PC (version 3.2.2) include the following upgrades:

  • support for the new versions of Apple's operating systems iOS 5 and Mac OS X 10.7 and dozens of new Android handsets;

  • improved loss protection for the video stream;
  • increased performance (Frames Per Second) of H.264 video, improved rendering with Android’s OpenGL ES video, and decreased media delay for voice and video calls;  
  • increased productivity of mobile users, allowing videoconferencing on multiple mobile platforms with several participants;
  • new APIs for camera switching, arbitrary viewports, image mirroring, and device orientation;
  • a virtual camera interface for custom video streaming from mobile devices, offering new usage scenarios for end users;
  • an expanded set of SDK examples; and
  • improved acoustic echo cancellation technology that delivers better performance and sound quality on mobile devices.

"Quality across all platforms and time-to-market has been the driving force behind the massive uptake of our TeamSpirit engines, and we're proud to announce this latest version, which offers an even more sophisticated and rich plug-n-play API that is unparalleled in its ability to help our customers quickly deliver on the promise of anytime, anywhere premium-quality IP calling services," said Spirit DSP's product marketing director, Alexander Samarin.
