/phgvzqubdy23onei9j4l)
Step into the dreamlike world of Seoul Dreams, the latest sample pack from producer and songwriter Sung-Woo. With a deep love for lofi and R&B, Sung-Woo blends classical influences with modern textures to create an evocative soundscape that feels personal and immersive. In this interview, he shares his journey from classical piano to music production, the inspiration behind his samples, and his unique approach to vocal production and sound design.
Splice: Tell us about yourself – what led you to production and creating samples?
Sung-Woo: I’m a producer and songwriter with a passion for crafting dreamy, lofi/R&B sounds that evoke emotion and atmosphere. My musical journey began with classical piano training at a young age. While I appreciated the discipline and structure of classical music, over time, I began to feel limited by the constraints of playing pieces composed by others. It sparked a question in my mind: What if I could create music that was entirely my own—original, unique, and unbound by traditional rules?
This curiosity led me to experiment with music production during middle and high school. At first, I dabbled in genres like dubstep and pop, discovering the joy of shaping sounds and layering melodies. My passion deepened in college, where I pursued a Bachelor of Arts in Music. During that time, I immersed myself in production by watching countless YouTube tutorials, collaborating with other musicians and producers, and pushing my boundaries into genres like lofi, R&B, and hip hop. These experiences allowed me to develop my own sound—a blend of introspective textures, soulful melodies, and innovative production techniques that reflect both my classical roots and modern influences.

Splice: What inspired the sounds included in this sample pack?
Sung-Woo: The Splice sample pack is designed to embody the feeling of being lost in a dream. It’s a sonic exploration of time, space, memory, and emotion. Through bittersweet chords, ethereal vocal melodies, and reflective drum patterns, the pack captures the duality of nostalgia—both its beauty and its weight. I leaned heavily on spatial effects like lush reverbs and polyrhythmic delays to create an immersive and introspective mood, allowing listeners to feel as if they’re floating through a hazy memory.
Each sound was inspired by the organic imperfections of life—the quiet moments and fleeting thoughts. The chords and melodies invite introspection, while the textures and effects evoke the sense of a journey through one’s subconscious. It’s not just a collection of sounds; it’s an invitation to dream, reflect, and create.

Splice: Are there any other insights you’d like to provide readers around this instrument/piece of gear?
Sung-Woo: This sample pack was born in the quiet hours of the night, created in a bedroom studio with just a keyboard, steel guitar, and vocals. My goal was to preserve a raw, ‘lofi’ quality that feels authentic and unpolished, embracing the beauty of imperfection. You’ll hear little details like guitar taps, the sound of cups clinking, and even the faint hum of cars passing by outside. These ambient, organic noises give the pack a unique character that sets it apart from highly polished, commercial sample packs.
For me, originality was key. I wanted the samples to feel personal and intimate, like a musical diary rather than a product. Every sound carries a story, a moment of creation, and a connection to the environment where it was recorded.
Splice: What’s your approach to vocal production?
Sung-Woo: When recording vocals, I aim for precision and emotional resonance. I typically record line-by-line, carefully comping the best takes together and blending them seamlessly with crossfades. There are times when I’ll record just a single word or phrase multiple times until it’s perfect. Consistency is important to me, so I try to complete all vocal recordings for a track in one session to ensure my voice maintains the same tonal quality throughout.
I also prioritize capturing the emotional essence of the lyrics, using subtle variations in delivery to enhance the story being told. The result is a vocal performance that feels polished yet deeply human.
Splice: What are some processing techniques you commonly employ when producing vocals for a sample pack?
Sung-Woo: In terms of processing, I often rely on pitch and formant shifting to experiment with tone and create unique vocal textures. EQ is essential for sculpting frequencies, and I use reverb and delay to add depth and space. I’ve developed several pre-made vocal effect chains tailored for different purposes, such as lead vocals, adlibs, and harmonies.
For lead vocals, I aim for clarity and presence, using processing to ensure they sit front and center in the mix. Adlibs, on the other hand, are treated more creatively—they might sound distant, drenched in reverb, or modulated for a dreamy effect. Harmonies are given a wider, brighter treatment to fill out the stereo field and complement the lead vocals. These techniques ensure that each vocal layer has its own distinct place in the mix, enhancing the overall production and making the samples feel dynamic and layered.
