Microsoft Real-Time Communication (RTC) Testing Service
Professional Audio & Video Validation for Video Conferencing Laptops
What Is Microsoft RTC?
Microsoft Real-Time Communication (RTC) is a comprehensive testing and quality validation framework designed for laptops and mobile computing devices. Its purpose is to ensure stable, clear, and reliable audio and video performance in real-time conferencing environments such as Microsoft Teams.
RTC testing focuses on real-world usage scenarios rather than isolated component specifications. It evaluates the complete system-level experience, including microphones, speakers, cameras, system integration, and hardware–software collaboration.
What Problems Does Microsoft RTC Aim to Solve ?
In today’s hybrid work and remote collaboration environment, users have very low tolerance for poor video conferencing experiences, such as:
-
Audio dropouts, echo, and background noise
-
Unclear speech or unstable volume levels
-
Blurry video, incorrect exposure, or poor low-light performance
The core objective of Microsoft RTC is simple:
To ensure that a laptop performs like a professional conferencing device in real meeting environments.
What Does Microsoft RTC Testing Include soft RTC ?
Audio Performance Evaluation
RTC evaluates not only microphone and speaker components, but the overall system-level voice experience.
Audio performance is categorized into three tiers: Entry / Mainstream / Premium
Key differentiators include:
- Microphone Signal-to-Noise Ratio (SNR)
- Microphone array architecture (dual-mic / multi-mic)
- Speaker Total Harmonic Distortion (THD)
- Echo coupling performance
- Near-field and far-field voice performance
RTC specifies defined validation tools and methodologies, including:
- Azure Speech Tool
- Talk Analysis Suite (DNSMOS / AECMOS)
- Windows Studio Effects (Voice Focus)
- Voice Clarity HLK
Video Performance Evaluation
Video performance is also divided into three tiers: Entry / Mainstream / Premium
Each tier sets different requirements for image quality, low-light performance, frame rate, and field of view (FOV).
Core measurement parameters include:
- Luminance
- Gamma
- MTF (Sharpness)
- Spatial and Temporal SNR (Noise Performance)
- Color Accuracy (Delta-C00)
- Frame Rate (Low-light / High-light)
- Texture Acutance (Detail Retention)
- Field of View (FOV)
- Video Latency
Real-World Scenario Based Testing
RTC testing is not limited to ideal laboratory conditions. It simulates real-world environments such as:
- Open office spaces
- Small meeting rooms
- Work-from-home setups
- Various user distances and angles
This ensures that products meet Microsoft’s expectations for conferencing quality under actual usage conditions.
