lakers! >> reporter: or does it? from the sound of it, you might forget that this year's nba playoffs are unfolding in a fan-free arena. thanks in large part to mark ditmar and fire house productions. >> we're taking human voices and trying to make it sound like an actual crowd in an 18,000 seat arena. >> and you anemic human voices and they're reacting to everything that's going on. >> correct. >> reporter: it was almost impossible to imagine when the nba suspended its season in march. the league's biggest star, lebron james said it would never happen. >> play games without the fans? no, it's impossible. i ain't playing. >> mark ditmar heard lebron loud and clear. >> it was like well, that's a giant bummer. i woke up the next morning and had this crazy idea in my head of what if he didn't know there were no fans. >> the man in charge of live

presentation was wondering the same thing. >> we want to create the environment the players are used to, knowing that if the players feel comfortable, they'll play better. >> what was your initial response to his idea of how they could help bring that regular arena sound into an empty arena? >> my response was let's do it. let's try it. figure out a way to bring this experience home for the fans and the players. >> the start of the idea was putting a multichannel sound system like we have sitting around us right now around the court. >> reporter: it feeds into ten large clusters of speakers all facing the court. >> and how do you create this? you didn't get 18,000 people in an arena and start recreating this sound. >> a lot of this is sound effects libraries. >> reporter: they spent weeks building an audio library with layers of sounds. and a system to deliver them. >> they're launch pads with buttons and each vertical row is a set of information. so, murmur might be one row,

1-8. the game director is talking to them some, narrating the story, but they are somewhere between playing a video game, playing a musical instrument. >> reporter: audio sweeter nathan -- >> let's hear a base murmur. >> reporter: -- joined us from the orlando bubble to show us how it works. >> you have eight additional audience levels, basic audience pre-game kind of level, that being level one. level eight being basically everybody in an arena on their feet cheering, clapping. and really kind of scale up the sound and scale it back down. >> they first demoed the technology for myers at a gym near fire house productions in new york's hudson valley. >> had the speakers set up and everything. and as they started layering the sounds, you got the feeling you were in a building with 17,000 people. and at that moment i knew it

would work. >> reporter: down in orlando, each game was an opportunity to improve. >> the more practice those guys have in doing games, the better they get at it. there's a lot of nuance to basketball, so you have to learn certain situations. and they have really learned how to sweeten those situations to sound extremely natural. >> we layer multiple reactions based on what may happen. >> air ball! air ball! >> let's go build it up and let's go really big. >> that's relatively close to the level we were at when he hit the three-point in overtime the other night. >> pulls up, three-pointer, bang, bang! it's good! >> if you just listen to the crowd, it certainly sounds fake. you can hear that it is synthetic. then you get the basketball bouncing up and down and you get the players yelling at each

other and all that. now it's so far down in your brain that it sounds completely realistic. >> hammers it home! >> it even surprised toronto raptors coach nick nurse. >> it doesn't feel that much different. i know that's kind of hard to believe, but it really doesn't. >> the refs asked early on if we were going to have ref, you suck, and things like that. and one team came forward and said, our fans boo. we want booing. >> and the nba took those specialty sounds a few steps further. adding ones associated with each team's home arena like in miami. >> the p.a. announcer, when there's two minutes left in the quarter, he says two minutes, dos minutos, so we got him to record that, send that to us, and when that happens during the

game when there's two minutes left in any quarter, we play it. >> say hello to the virtual fans. >> that's right. they even added fans. >> we wanted to give fans the opportunity to access the game. they've been very excited to be involved and i think the players get a little bit of energy from looking up in the stands and seeing -- not in the stands -- but on the screens and seeing fans there live. >> reporter: do you have those veteran play by play announcer called the first two rounds of the nba playoffs for tnt. >> the crowd is kind of like the broadcasters and broadcast symphony. it's like the orchestra that fills in the back of a call. on first brush, just turning it on, you think, my gosh, there is a crowd. it feels real. >> do you have those moments
