ABOUT US
WAH AUDIO PRODUCTIONS
WAH Audio Productions is a multidisciplinary company founded in 2022 by Wouter Hulsbergen. Operating under various names—including WAH Audio Productions, ALTURE, Wouter Hulsbergen, and IBEX MUSIC—Wouter works across the music industry as a Mastering Engineer, Producer, Composer, Songwriter, Mixing Engineer and Recording Engineer.
What began as a dream over a decade ago has evolved into a thriving career, currently pursued alongside a Bachelor's Degree at ArtEZ Conservatory in the Netherlands, where Wouter refined his skills and expanded his musical expertise.
Originally a Hardstyle producer, Wouter’s artistic vision expanded during his studies. He shifted towards mastering, music for media, and producing for other artists, but also developed a deeper understanding of mixing, songwriting, foley, and sound designing. During a specialized minor at eMastering, Wouter discovered his passion for mastering, while his love for composing and creating music for media grew during an internship with Tom Hoesstee.
At WAH Audio Productions, we work with high-end plugins from brands such as Universal Audio, FabFilter, Eventide, Soundtoys, Softube, Xfer, and Orchestral Tools to ensure the highest possible quality in every project.
