Measure audio input/output latency and round-trip delay for real-time audio applications. Test microphone-to-speaker latency, detect audio buffer issues, and verify low-latency audio performance. Critical for music production, live streaming, or real-time communication apps.
Audio latency is the delay between when sound is produced and when it's heard. Professional audio interfaces achieve latencies under 5ms, while consumer devices typically have 10-50ms latency. For music production, latency under 10ms is essential to avoid timing issues. This tester helps you measure your actual audio latency.
Start with the live tester below. Supporting details, FAQs, and troubleshooting guidance are placed after the tool so the main action is easier to find and use immediately.
Measure audio input/output latency and round-trip delay.
Common problems
If the live tester does not behave as expected, these are the first checks most users should try before assuming the hardware is broken.
Test in quiet environment for accurate results
Use quality audio equipment for best results
Test with different browsers - latency varies
Check audio buffer settings - lower buffers reduce latency

Test your keyboard input, detect dead keys, and verify all keys are working correctly.
Test mouse buttons, scroll wheel, pointer tracking, and touch input.
Test your microphone input levels in real-time. Verify microphone is working.
Test your speakers or headphones with reference tones.
Helpful questions
Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.
Open the live audio latency test on this page and follow the prompts shown in the tester area. The tool runs directly in your browser, so you can check your device without installing additional desktop software or signing in.
Check browser permissions, confirm the device or browser feature is enabled, and reload the page if needed. Many browser-based testers depend on permission prompts, secure context support, or hardware access that must be approved before the test can run fully.
Music production - ensure low latency for recording. It can help you confirm whether the issue is caused by the hardware itself, a browser permission setting, or a system configuration problem before you spend more time debugging.
