I didn't click the link, but you can also cook up your own echo effect by copying your audio track, paste to the track below (or above) and set it several frames back. Then play with deepening the tone and adding more tracks.
If you're miking the audio yourself, use two or more mics with the first nice & close to your speaker's lips, then each sucessive mic placed much further away, then slide the tracks back a few frames, etc.
