Welcome to Kupper Sound Mastering Lab

I’ve been a music and sound recording professional for over 38 years. To achieve the best possible sound from your mix is my goal, using a combination of digital and analog tools. It’s not all about volume, but quality of sound and musicality. While sonic excellence is extremely important, so is soul, vibe and character.

Mastering clients include: Ariana Grande, Pink, Diana Ross, Shakira, Jennifer Lopez, Earth, Wind & Fire, Katy Perry, Gloria Estefan, Amy Grant, Rob Thomas, Blondie, Christina Aguilera, Frankie Knuckles, Janet Jackson, Judy Garland, Universal Records, Sony/BMG, Capitol Records, Motown Records, Sony Legacy, RCA Records, C&C Music Factory Records, SoSure Music, dotdotdot Records, Nervous Records, Republic Records amongst many others.

My fees are not the least nor the most expensive in the business, but the quality of sound is top notch.
