0550 – Mic Muck-Ups Solved!: Echos

2022.07.04 – 0550 – Mic Muck-Ups Solved!: Echos

Echo

It’s not quite the same echo as you get when talking in a tunnel or cave, where your sound comes back a split second later, but it’s the same principle: the sound of a voice is reflected off rather than absorbed by the environment in which you are making the recording. This ‘colours’ the voice and makes it sound thin – great if you want to paint a picture of being in a huge empty warehouse but less good if you are not. In fact, that’s a good point, the larger and emptier a room, the greater the problem may be. A good pre-recording check is to clap your hands once and hear what sound you hear – but remember, the mic will pick up noise in a different way from your ears will, as your brain will help compensate for some of the potential distortion. A smaller room, one with carpets and curtains or lots of different edges to break up the soundwaves as they move around the room, will reduce the echo effect as the waves won’t return to the mic at the same time.
