Delay time (seconds)
The amount of delay between the echoes, in other words the length of each echo.
Usually a number between 0 and 1. A value of 0 means no echo, and a value of 1 means that each echo is exactly as loud as the original, so this merely extends the current selection unchanged. A value of 0.5 reduces the amplitude or loudness of each echo by half each time, so the audio dies out quite slowly. Smaller values make it die out more quickly. Values above 1 increase the amplitude of the echo each time, which you could use as a special effect.
|Because echoes are often added to the original audio, the processed audio will often have a higher peak level than the original. If clipping results, you can the Echo effect, to a lower level, then apply Echo again.|
- If you want a loop with no volume changes, use instead.
- You can also create echoes with which generates the additional audio needed for your chosen delay time and number of echoes.

- plays a short preview of what the audio would sound like if the effect is applied with the current settings, without making actual changes to the audio. The length of preview is determined by your setting in , the default setting is 6 seconds.
- applies the effect to the selected audio with the current effect settings.
- aborts the effect and leaves the audio unchanged.
