Echo Test
Check your microphone and speaker connection using real-time echo loopback and latency measurement.
Headphone Warning
Using speakers may cause feedback. Headphones recommended for this test.
Echo Inactive
Your microphone input is captured and played back through your speakers with a short delay, allowing you to hear yourself in real-time.
Understanding Audio Loopback and Latency
Echo testing, also known as loopback testing, is a fundamental way to verify your entire audio chain is working correctly. By hearing your own voice with a slight delay, you can confirm both input and output are functioning.
What is Audio Latency?
Latency is the delay between when sound enters your microphone and when it exits your speakers. In professional audio, low latency (under 10ms) is crucial for real-time monitoring.
Why Use Echo Testing?
Echo tests help identify issues like: microphone not picking up sound, speakers not outputting audio, audio routing problems, and excessive system latency.
Avoiding Feedback
When using speakers instead of headphones, the microphone can pick up the speaker output, creating a feedback loop. The delay in this test helps prevent runaway feedback, but headphones are still recommended.
