Hi, I'm Álvaro Callejo, a Spanish sound designer based in Madrid with extensive experience in sound design, recording, editing, mixing, and music production for film, video games, television, and advertising. I've collaborated with Electronic Arts, Warner, Netflix, TVE, Disney, and other leading production companies, delivering complete end-to-end audio solutions from concept development to final stereo and 5.1 mixes. As a certified Pro Tools expert, I specialize in creating immersive soundscapes that enhance storytelling, strengthen emotional impact, and bring projects to life. Whether designing sound from scratch, crafting complex audio environments, recording ADR, or mixing for broadcast and interactive media, I focus on using sound as a narrative tool that adds depth and value to every production. Alongside sound design, I am also a music producer and composer capable of creating original music across a wide range of genres and styles, adapting each composition to the creative and emotional needs of the project. I work from my professional studio in Madrid, collaborating closely with clients and creative teams to ensure every project is delivered to the highest technical and artistic standards.
