Case Studies: Media Foundation

In the process of upgrading the audio conferencing features of their flagship product from Windows XP to Windows 7, one of Saturn Systems telemedicine clients discovered that support for acoustic echo cancellation (AEC) was no long supported in the Microsoft Real-Time Communications libraries. Saturn Systems engineers were asked to replace the system with a custom solution and a new audio codec. Using Microsoft’s Media Foundation technology, a replacement was developed that included the necessary loopback functionality required for echo cancellation. The resulting component provided better quality audio and efficiency than the original solution and was integrated with the core product successfully.
