Create your reflection/reverb free zone in the very cheap

YouTube content creators will often hear quite a bit of echo in their videos or a Twitch streaming will get complaints from his teammate if they use microphone to make productions in their spacious room or studio without treatment. Because there is going to be a really loud reflection from the walls, even if you just speak directly into the microphone. And they come in a delay, that is what causes reverb or echo effect and ruins your audio job. Typically, the louder you speak, the larger your room, the more noticeable the echo.      
 
The goal is to absorb the reverberating sound that will be picked up by the microphone. Set up your echo free studio on a budget is the topic of this blog post, that means the relatively “costly” acoustic panels (compare with stuff laying around your home) are not one of our choices. Mattresses, towels and blankets are pretty good at absorbing frequency across the frequency spectrum, extremely efficient at treble. But keep in mind, it should be the blankets with coarser surface. For a better result without spending much more, there are specifically designed sound blankets for your consideration.     
 
After collecting all the used materials, you should think about where to place them to block echo efficiently. There are actually four reflection points in your room: floor or desk, front and back walls, side walls and ceiling. Literally any flat surfaces reflect sound. Since you will speak into the mic, the first point is front wall, then the sides. And the desk is overlooked most of the times, but which can be problematic as well. Just a reminder that when two boundaries meet, the bass builds up, making sound bounces worse. So the corner is definitely not a good place to do any audio-related project.
 
Knowing where to hang the blankets, but how to place them on to a flat floor? Spring clamps will work great enough to hold the moving blankets to shelves. Or a much simpler and cheaper one-off method is to use gaffer tape to paste the blankets onto the walls and take them down when you finish recording or streaming.        
 
It is not only for video production and streaming but also for webconferencing and even interview. Up your game of audio with just a simple trick!
