Hi, I’m Ilpo Kärkkäinen. With 16 years of experience mastering for top labels and artists, I help bring out the best in your music.
My analog-centered process gives your tracks clarity, depth and impact, with the best digital tools used where they offer a genuine advantage.
“Ilpo brought my premaster to life in a way I didn’t think was possible. Clean, precise, and powerful are a few words to describe it.”

The Professional Mastering Advantage
Expert Analysis and Objective Evaluation
The most valuable part of mastering is having fresh, seasoned ears evaluate your music objectively. I bring 30+ years of perspective in electronic music as a producer, DJ, and mastering engineer.
The Full Picture
Most production setups can’t reveal what professional mastering-grade systems catch. I’ll spot the issues your monitoring misses and ensure your music translates perfectly – from AirPods to festival sound systems.
Analog-First Processing Philosophy
Premium analog equipment gives your music the three-dimensional depth and harmonic richness that digital-only mastering can’t match. Digital tools come in for precision tasks where they genuinely improve the analog foundation.
The gear I use includes:
- Conversion: Prism Sound Titan
- Processing: Neve Master Bus Transformer, Elysia Museq, Elysia Xpressor, Elysia Xmax, Cranborne Audio Carnaby HE2, Nihon Kohden 427 transformers
- Monitoring: Genelec UNIO PRM system with Genelec 8351B
Electronic Music Mastering Expertise
Your tracks get genre-specific treatment that delivers loudness, clarity, and punch – always respecting the material and your goals.
Release With Total Confidence
Stop wondering “does this sound right?” Professional mastering means you upload to Spotify, send to labels, or press vinyl knowing your music sounds its best.
How It Works
Step 1: Submit Your Project
I’ll listen to your music and get back to you to confirm and discuss any questions you may have. If I notice any problems or potential for improvement in the mixes, you’ll have a chance to work on them before we move forward with the mastering.
Step 2: Mastering Processing
Your music receives mastering processing tailored specifically to your requirements.
Step 3: Delivery
Receive your masters. You’ll have the options to download or stream in lossless quality. I offer unlimited revisions until you’re completely satisfied with the results.
What Clients Say
“Had some mastering work done by the wizard Resoundsound recently and this is a personal recommendation to labels/artists out there. Very impressed with the finished products, attention to detail is high, the tracks are 10x more alive. Big up Ilpo, technician!”
Antagonist
“I’ve worked with Ilpo on various projects and they have always been excellent. The results have been fantastic but more than that, he’s incredibly knowledgable, open and easy to talk to. Would 100% recommend”
Modal
