Audio Latency Test
Test your audio system's latency by measuring the delay between input and output. Lower latency is better for real-time audio applications.
Make sure your microphone and speakers/headphones are properly connected and configured.

Understanding Audio Latency
What is Audio Latency?
Audio latency is the delay between when an audio signal is generated and when it's heard. It includes processing time in your audio interface, drivers, and software.
Browser vs Native Apps
Web browsers typically have higher latency than native applications due to additional audio processing layers. Values of 50-150ms are normal for most systems in browsers. Updated standards below reflect realistic performance.
Latency Categories
- • Excellent: < 50ms (Optimized setup)
- • Good: 50-100ms (Typical desktop)
- • Fair: 100-150ms (Laptop/mobile)
- • Poor: > 150ms (Needs optimization)
Factors Affecting Latency
- • Audio interface quality and drivers
- • Buffer size settings
- • CPU performance and load
- • Audio software configuration
- • Operating system audio stack
Improving Latency
- • Use ASIO drivers (Windows)
- • Reduce buffer sizes
- • Close unnecessary applications
- • Use dedicated audio interfaces
- • Update audio drivers
