Echo is an audio effect which records an input signal to an audio storage medium, and then plays it back after a period of time. The delayed signal may either be played back multiple times, or played back into the recording again, to create the sound of a repeating, decaying echo.
The echo effect repeats the audio you have selected again and again, softer each time. There is a fixed time delay between each repeat. Like many other users, you can use MP3 Editor for Free to echo your tone on a series of repeats.
Follow the lead to add echo to an audio file:
To add an echo effect, you firstly need to launch MP3 Editor for Free and add an audio file to the waveform window. Then click “Effect” tab and choose “Echo” to specify detailed parameters or apply some popular presets to adjust the effect. Click “Preview” to listen to the music before adding the effects to the waveform to make sure you get exactly what you want. Click “OK” to add the echo effect to the selected region.
