NJT: Hello.
 

Raon ANC: Hello.
 

NJT: Can you introduce your company Raon ANC to our audience?

Raon ANC: Raon ANC is a company that develops and supplies realistic sound solutions. We came to the CES 2023 with a solution that can provide realistic sound in online performances such as YouTube. After COVID-19 broke out, there were many online performances on YouTube, but general users did not like online performances. Also, musicians and event planners did not like them, either. It is because even if musicians or planners create an atmosphere similar to that of a concert hall, it is not exacty the same as the offline concert.

We offer a great solution. 

If a singer sings while moving from right to left, we make the sound move together in real time as well. This has the advantage of being able to give the same feeling of moving from the right speaker to the left in a concert hall on YouTube. So it has the advantage of being slightly differentiated and feeling a more special sound.
 

NJT: Our audience watching this video can't hear the sound, but can you show us a little bit of what you just said through the screen.

Raon ANC: If you look there, in the case of the existing stereo, even if I move the sound from left to right, I just hear the sound in stereo on both sides. Applying our solution, the vocalist moves from left to right as the person sings. Then the sound moves from the left to the right, so you can hear the realistic sound. Similar to the concert hall, there is an advantage that you can listen to the music on YouTube with our system.

NJT: You said earlier that if you want to listen to BTS Jungkook's voice intensively, the listeners can do that. Could you please explain it?

Raon ANC: So, if BTS were to hold an online fan meeting all over the world, fans would connect to YouTube saying to other people, “Come to YouTube.” Then, if the fans want to hear Jungkook's voice louder, then the person in charge of the concert might just pull Jungkook's voice forward and let it be heard. Or you can pull out another team member's voice and let them hear more precisely.

Because the audience and the performer can communicate in real time while performing, it is possible to convey the feeling of being in a real fan meeting or concert hall.

NJT: Instead of hearing one-sided, the emphasis is on interaction and the fans can choose what to hear. 

Raon ANC: On YouTube, end users can't control the sound. In our system, when fans send a message saying, “I want to hear this, I want to hear that,” the mastering people can control it and deliver it to the end user.
 

NJT: Many people practiced the choir through Zoom during the COVID-19 era, but the sound did not harmonize well. I heard there is a solution for that part.

Raon ANC: Many people did a lot of choir and practice using Zoom, but the biggest problem is that the video conferencing system has mono sound, so there are many people saying that the sound quality is not good.

So, in order to solve the problem, we created a system in which musicians in Busan, Daejeon, and Seoul perform at their homes, and the band master puts together the performances online and transmits them with a 3D effect. It is expected to launch at the end of this year or early next year.

NJT: It's innovative. I'm really looking forward to it. Thank you so much for agreeing to this interview. I wish you good results.

Raon ANC: Thank you for visiting our booth. Thank you.
