■ Bibi Profile
A creator specializing in editing (tuning) vocals for vocal synthesis software. Since starting her activities in 2012, she has been in charge of vocal editing for songs produced by many Vocaloid producers such as Jin, *Luna, and Marasy. In addition, she has worked on the tuning of several virtual singer songs implemented in the smartphone game "Project Sekai Colorful Stage! feat. Hatsune Miku".
1)"This isn't a human!" I was really shocked.
Sasaki: When did you first become aware of Hatsune Miku, and what was the reason for that?
Bibi: I was originally interested in manga and anime, which were considered "subculture," and it was through that connection that a friend introduced me to Hatsune Miku, saying, "This is what's popular right now!" The first song I heard was "Miku Miku ni Shite Ageru♪" I remember being really shocked, thinking, "This isn't a human!" Since then, I've listened to various Vocaloid songs, seen singers and people who enjoy creating illustrations and videos based on the songs, and I've become very drawn to the culture centered around Vocaloid.
Sasaki: It's true that this culture originated on Nico Nico Douga, but back then, there was also the background of internet culture like 2chan. I remember a sense of celebration, like, "Wow, something this interesting has come out on the internet!" We even waved leeks as a symbol of joy. So, Bibi-san, you went through that phase too.
Bibi: That's right. Until then, the internet was simply something I consumed, but since I had originally been drawing illustrations, it stimulated my desire to "create something myself!"
Sasaki: It was a time when everyone was listening to Hatsune Miku because they wanted to hear her. Then came the "Melt Shock," and we got a sense of family with Kagamine Rin & Len, Megurine Luka could sing in English, Megpoid was a bit of a rival, and oh yeah, Gakupoid was a shock too... Back then, there was a thrilling sense of not knowing what would happen and how everyone would use the characters. When Megpoid came out, I was surprised by the charm of her singing voice, which was completely different from Hatsune Miku's. Bibi, who are your favorite virtual singers and creators?
Bibi: My absolute favorite is Kagamine Len (laughs). That's one of the reasons why I love Giga. Also, cosMo@BousouP is a pioneer in making Vocaloids sing in a unique way. The impact I felt when I first heard "The Disappearance of Hatsune Miku" was incredible. I had never heard a song like that before, so I felt the immense potential of Vocaloid. I still love it to this day.
Sasaki: I see. That kind of edgy impact is unforgettable, isn't it?
2)"I'm tuning the voices with the desire to see the moment when the character shines."
Sasaki: When I listen to the vocals that Bibi has worked on, I get the impression that the intention is clear and easy to understand, and that the person who did the tuning is someone with a deep understanding of vocal and musical expression. Earlier we talked a little about "singers", but how did you become a "vocal tuning specialist"?
Bibi: I've always loved music and singing, but more than anything, I love characters. Ever since I learned about the expressive technique of covering songs with Vocaloid, my desire to express my favorite songs with these characters has grown even stronger. Now, I listen to human songs and think every day about how I could express them using the VOCALOID Editor. I've studied the project files that KannazukiP has made publicly available so many times that I practically wore them out.
Sasaki: I see. Bibi's love for the characters, or rather, her desire to see them come alive, is what connects to the charm of her singing. I can even sense her determination to realize the expression she loves.
Bibi: I think my desire to see the moment when that character shines is what ultimately led me to specialize in voice tuning. If I liked music, I could pursue other paths like composing, but I love voices, and I want to pursue how that character can shine the brightest. If I had to put it into words, it would be "fandom activities". I do voice tuning as a form of fandom activity, so I think I'll continue doing it even if I end up alone in the future (laughs).
Sasaki: Perhaps that's what makes Bibi so appealing to listeners. The characters Bibi likes are also characters that everyone likes, aren't they? It feels like the nuances that everyone loves and wants to hear resonate with Bibi's feelings and become embodied in her music. For example, in Marasy's "Mugen no Ticket," there's a moment where you feel like, "This is where KAITO's eyes suddenly opened wide". Of course, Marasy's song is wonderful, but you can also feel the dynamism of the character's energy coming alive through his voice.
Bibi: Thank you. However, my style of work is based on the fundamental premise that I borrow everything from other people. That's why I want to cherish the songs and characters. In the end, that might lead to what everyone is looking for.
Sasaki: Bibi's vocal tuning, while using Vocaloid, also has a very lifelike quality. Do you ever expand on your vocal tuning ideas by singing yourself?
Bibi: Although I only sing as a hobby, when I first started, I would adjust the vocals while singing. I would try singing along, thinking about how to reproduce the original, and it felt like I was singing together with the song.
Sasaki: This might be the first time I've heard someone describe the feeling of "singing together." Singing along with the characters...that sounds great. Bibi, you really must love the characters.
Bibi: Yes, that's all it took to get this far (laughs).
Sasaki: Conversely, are there any specific points you focus on when tuning the voice to bring out the "Vocaloid-like" quality?
Bibi: I think it's about not drastically altering the dynamics. With humans, there's quite a bit of variation in vocal volume, but because it's not human, that difference isn't as pronounced. I think that's what makes it sound like a Vocaloid.
Sasaki: Bibi-san, it seems you also like that "saturated voice" feeling that's characteristic of Vocaloid, or that "overload" feeling where the Vocaloid's voice gets louder due to the volume difference at the transitions.
Bibi: I really love it. That's why I always set my attack power to a high level. My absolute favorite is Kagamine Rin & Len's Act 1 (the nickname for the first released version). That's the image I have of Vocaloid.
Sasaki: For Kagamine Rin & Len act1, we recorded their voices dynamically, partly to differentiate them from Hatsune Miku. We asked Asami Shimoda to push her voice to its absolute limits, and that resulted in that overloaded feeling. It wasn't an easy style to control, but it certainly had that dynamic quality that's characteristic of Vocaloid.
