Audio Engineer & Studio Owner
Tonstudio Audionique • Self-employed
Dec 2024 - Present • 1 yr 8 mos
As the founder and audio engineer of Tonstudio Audionique, I provide professional audio services across a wide range of applications, including music production, mixing, mastering, audio restoration, vocal editing, podcast production, ghost production, and sound design. I have worked with artists, content creators, and companies worldwide, delivering industry-level audio quality for music releases, film and video sound design, game audio, podcasts, and commercial projects. My work includes mixing and mastering full music productions, restoring and cleaning damaged or low-quality recordings, and enhancing vocal recordings to achieve a clear, modern, and professional sound. In addition to client work, I am also the mastering engineer for the electronic music label Illusions, ensuring consistent, competitive, and release-ready masters for digital distribution and streaming platforms. With over 15 years of experience in music production and audio engineering, I combine technical precision with a deep musical understanding to deliver results that translate reliably across all playback systems. My focus is always on clarity, balance, emotional impact, and professional industry standards.

I worked with Julian for the first time on this project, and I couldn't be happier with the experience. His response time was exceptional, and the delivery was excellent. He understood exactly what I was trying to achieve and communicated clearly throughout. I actually made a slight mistake when explaining...

Second time working with Julian now and he's always been exactly what I needed. Easy to work with, very outgoing and professional. Even often goes above and beyond to help me work out other small issues I have. Cannot recommend enough!

I had poor experiences here before, but Julian really paid attention to my project and understood what I wanted from an audio perspective, very proactive and with attention to detail. I'm very pleased and will continue to work with him.

Extremely fast turn around for a fantastic end result, can only sum up the end result as 'plug and play' as it literally just feeds perfectly back into the edit.
