Adding echo to audio in iMovie
Is it possible to add an echo effect to the audio tracks in iMovie?
iMac G5, Mac OS X (10.4.2)
Yes, sort of like a reverb effect?
One way that comes to mind is to select the clip you want to add the echo. If you only want to apply it to part of the clip, then split the clip as needed to get a single clip with the one part you want to echo.
Now select that clip and use the Extract Audio command. This command will create a copy of the audio in the clip, paste it on the timeline under the clip, and mute the audio in the original video clip. So right now there is no difference if you play the clip.
To create your echo, simply un-mute the audio in the original video clip. Then grab the extracted audio below and drag it to shift it slightly. The more shift the more pronounced the echo. You can copy and paste the extracted audio if you need to create additional echos.
Also keep in mind that the original video audio and the extracted audio are at 100% volume, so that clip will play at double volume. So you may need to go back in and 50% both clips or maybe the original clip at 80% and the extracted at 20% to make the echo faint. You get the idea. Goof around with it until you find something that works.
Have fun,
