Having trouble recording loud sounds, bangs of your airsoft? Or a grenade you made?
Record it in a garage lol, the echoes make it sound so great.
There is a youtube version, but the sound is horrible, don't recommend it.
YouTube - Indoor tokyo marui mp5a5 shooting
Also this is the apartment's garage, if i could make people get their cars out, it would be a perfect airsoft zone lol.
