About the Echo / Delay
Repeat the sound with adjustable time and feedback. Pro mode can sync echoes to the song’s BPM.
How to use it
- Drop an audio file (MP3, WAV, M4A, OGG, FLAC) or a video into the box.
- Pick a preset or adjust the controls — echo time, repeats and amount. Hit play to hear it live and use “Compare” to hear the original.
- Download as MP3 or WAV. Nothing is uploaded: the processing runs on your device.
Questions
