📖 FAQ

What is an echo effect?

Echo is the effect of sound reflecting off surfaces and arriving at the ear with a delay. Unlike reverb, echo produces distinct, recognizable delayed repetitions. In audio processing, echo simulates this by delaying the original signal and repeating it with decreasing volume.

What is the difference between single, multi, and ping-pong echo?

Single echo produces one delayed repeat; multi echo produces multiple gradually fading repeats; ping-pong echo alternates between left and right channels for a stereo effect. Ping-pong is great for music production and creative sound design.

What delay time should I use?

Depends on the desired effect: 50-100ms for thickness (like chorus); 100-250ms for clear echo; 250-500ms for spatial echo; 500ms+ for rhythmic echo. In music, delay times synced to BPM are common.

Is audio uploaded to a server?

No. All audio processing is done locally in your browser using the Web Audio API DelayNode. Audio data never leaves your device.

What is the difference between echo and reverb?

Echo produces distinct, spaced repetitions; reverb is many dense reflections blended into a continuous decay tail. Simply put: echo is like shouting in a canyon, reverb is like speaking in a room.
