Echoes or reverb is the performer’s voice bouncing from the walls, ceiling and floor and arriving at the microphone late—after the original voice. And not just once. Several different delays depending on the size and dimensions of the room. So you are asking the software to remove the performer from himself, many thousand times.
That’s why we didn’t come racing to your rescue when you asked that question. And that’s why reverb/echo is one of the four horsemen of audio recording.
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.)
There is a Hollywood way to rescue a performance with that kind of damage. Write down the words and either have the original performers say them again in a quiet room, or hire actors to do it in a quiet room. This looping and overdubbing happens in more movies than you think.
You should go through this once to rescue the show and cure you of ever shooting sound that way again.
