About Me
Meet the engineer behind the sound
I’m Kaiden — an audio specialist based in Basel, Switzerland.
With over 10 years of experience in sound design, editing, and mixing, I’ve worked in Brazil, South Korea, and Switzerland helping creators, authors, podcasters, and indie studios bring their stories to life through sound.
I studied Audio Production at SAE Zurich, then spent two years running my own recording studio in Brazil before moving into international post-production work. My background spans dialogue editing, SFX, music production, sound design, and audio for games.
Now back in Switzerland, I focus on delivering high-quality post-production that’s accessible, personal, and stress-free — without agency-level prices.
When I’m not crafting audio, you’ll find me learning languages, cooking, or rewatching The Office for the 20th time.
Your sound. Your story. Your style.
Here’s a selection of projects that showcase my approach to audio

League of Legends: Rise – Sound Redesign
Game Audio · Sound Design · Cinematic Mixing
This fan-made sound redesign replaces the original cinematic audio with fully custom sound effects, atmospheres, and transitions. The goal was to strengthen impact, clarity, and emotional pacing while matching the visual rhythm of the cinematic.
Built from scratch using layering techniques, dynamic mixing, and game-focused sound design methods.
Created purely for demonstration purposes — not affiliated with Riot Games.
Egda Carolyn – Saudade do Teu Beijo
Music Production · Mixing · Vocal Enhancement
A full mix and vocal treatment of Egda Carolyn’s track Saudade do Teu Beijo. I worked on improving vocal clarity, balancing the instrumental arrangement, and shaping the overall tone to reflect the song’s emotional character.

Corporate Communications Podcast – Internal Project (Excerpt)
Podcast · Dialogue Editing · Vocal Enhancement
This is an excerpt from an internal corporate podcast produced for employee communications. The full project cannot be shared for confidentiality, but this sample demonstrates my workflow for dialogue cleanup, tonal balancing, pacing, and preparing a broadcast-ready, consistent mix aligned with internal brand standards.
Canción Naturaleza – Foley & Sound Design
Foley · Field Recording · Organic Atmospheres
A sound design piece built entirely from original field recordings captured in a forest environment. Wind, leaves, footsteps, textured ambience, and natural elements were transformed into a cohesive soundscape that blends realism with musical rhythm and mood.
This project focuses on emotional, organic audio storytelling using real-world textures.
