Do your podcasts sound like they were recorded in a shower? While some podcasters might enjoy the reverberating sound similar to yelling from on top of the Grand Canyon, most want to have a clean sound, without the echo. If your podcast recordings have an echo quality, this post will give you some tips on how to get rid of that.The echo sound is usually created when sound waves from your voice hit a wall and bounce back, creating, in this case, an unwanted reverb effect. To get rid of this, we have to place an absorbing object in between your voice and the walls in your recording space.
The way to achieve this is with acoustic foam. This type of sound treatment acts as a sponge absorbing the sound from your voice, preventing it from bouncing off the walls and coming back into the microphone, and putting the unwanted echo sound in your recording.

If you’re looking for a cheap way to get up and going fast. Hang sleeping bags or heavy blankets on the walls in your recording space or purchase “Eggcrate Mattress Foam” from your local department store. (That’s the little egg shaped foam toppers ever 90’s household had on their beds!)
