Severe Echo - can it be fixed?

I have a problem with a recording with a bad echo - not just a reverb. The recorder captured the initial input and also processed it and recorded that with the small delay. See the sample attached. Any technique to clean this up? It would seem to need something that can take the first instance and remove those sounds at the timing of the second instance. Appreciate any help if possible.

No. Echoes are one of the four horsemen. One of the guaranteed ways to kill your show.

You can try duplicating the track (Control-D) and then slide the new track later than the other with the Time Shift Tool (two sideways black arrows). Audacity will try to play both tracks together, so you can push a little, play it, push a little more, play it, etc.

Sorry. Missed a step. After you duplicate the track, Effect > Invert, so it’s set to cancel.

Thanks Koz

I had thought of that cancelling but unfortunately it doesn’t work, for two reasons. 1st the two sounds are not totally identical, and even if it did, secondly, then the echo of the shifted track would not cancel out so it would just delay the echo more :frowning:

This is all four.

The Four Horsemen of Audio Recording (reliable, time-tested ways to kill your show)
– 1. Echoes and room reverberation (Don’t record the show in your mum’s kitchen.)
– 2. Overload and Clipping (Sound that’s recorded too loud is permanently trashed.)
– 3. Compression Damage (Never do production in MP3.)
– 4. Background Sound (Don’t leave the TV on in the next room.)
