Echo Effect

What is Echo Effect?

Echo Effect lets you record or upload audio and apply real-time echo and delay effects using the Web Audio API. Adjust delay time, feedback, and mix to create anything from subtle room reverb to dramatic canyon echoes.

How to use

1. Record audio using your microphone or upload an existing audio file (MP3, WAV, OGG).
2. Adjust the echo parameters — delay time (ms), feedback (how many repeats), and dry/wet mix ratio.
3. Preview the effect in real time, then download the processed audio file with the echo applied.

Result

A podcaster records a spooky intro, sets delay to 400ms with 60% feedback and 50% wet mix, creating an eerie cave echo perfect for their horror episode.
