Test Bluetooth Delay, Quality & Background Noise
What we do
Are your wireless earbuds lagging during games or videos? Our Round-Trip test plays a precise audio tone and calculates the exact millisecond delay before your mic detects it.
Want to know exactly how you sound to other people? Activate the Loopback feature. Speak into your microphone, and our engine will echo your voice back to you 1.5 seconds later.
Before you jump onto a professional Zoom call, use our Noise Analyzer. It listens to the ambient sound in your room and calculates the average decibel (dB) level to ensure it is quiet.
Watch your voice represented in real-time. Our high-speed HTML5 Canvas visualizer draws the live frequency data of your microphone, helping you spot audio clipping or static.
To ensure an accurate test, our engine disables your browser's default echo-cancellation and noise-suppression algorithms, giving you access to the raw, unfiltered feed of your hardware.
Your privacy is absolute. The audio data is processed entirely inside your local browser using the Web Audio API. Your voice is never recorded, saved, or uploaded to any servers.
