The IC3 Media-Quality team is a small team with a wide scope. We are developing a flexible yet precise test framework that allows us to validate the end-to-end media quality of Teams calls and conduct comparison tests to ensure the best call quality for end users.

Our task is to validate audio quality and related aspects like noise suppression and echo cancellation, as well as video quality and related metrics like video resolution, frame rate, and quantization. We also look at screen sharing use cases and set metrics to quantitatively rate screen sharing quality.

Therefore, we also examine network aspects using a Netem network simulation.

Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
