Gig Summary
About this gig
A great mix deserves a master that makes it hit harder, sound wider, and translate everywhere.
I'm Julian Koehler, certified mastering engineer with over 15 years of experience in electronic music, club sound, and streaming optimization.
Working in a professionally calibrated studio with Focusrite 18i20, Adam A77X, Sonarworks SoundID Reference, and DT880 Pro, I deliver masters that are loud, clear, and competitive without sacrificing the energy of your original mix.
What's included:
Precision EQ, multiband compression, and stereo enhancement
Transparent loudness optimization (LUFS / RMS) for streaming and club playback
Tonal balance check without compromising your original vibe
WAV and MP3 master (320 kbps)
Unlimited revisions until you're satisfied
Please send:
Final mix or stems (WAV, AIFF, or 320 kbps MP3)
Notes or reference tracks for tonal direction (optional)
Genres I work with: EDM, Techno, Hardtechno, House, Hip-Hop, Pop, and more
Rated 4.9 stars by 200+ satisfied clients. An unmastered track leaves money, streams, and plays on the table. Don't let yours be one of them.

Hi, I'm Julian Koehler, audio engineer and founder of Tonstudio Audionique. With 15 years of experience in music production, my focus is on Techno, Hardtechno and electronic music, but I work across all genres.
I trained at the HOFA College and have since worked with artists, labels and content creators across Europe. My standard is simple: every track should sound exactly the way it's meant to, punchy, clear and ready for any system.
Beyond mixing and mastering I also offer vocal cleanup, podcast editing, sound design and custom EQ profiling.

FAQ
What is STEM mastering, and do you offer that?
STEM mastering refers to mastering separate groups of instruments or elements (stems) of a piece of music. Yes, I offer STEM mastering and can process each stem individually to achieve the best result for the overall picture.
What format should I send the files?
48kHz/24bit WAV files are best. I can work with mp3s, but this is not ideal. Please make sure there is no compression, EQ or limiter on the tracks or master/stereo output and at least a few dB of headroom with no clipping (-3dB/-6dB/-12dB).
How should I send the stems?
Feel free to send me the stems as a ZIP file here in the chat or via a DropBox, WeTransfer or GoogleDrive link. Please include a rough mix of your song. You are also welcome to include references, but they should be similar to your track. Before placing an order, please contact me first.
How loud do you master the tracks?
I master tracks to a loudness level that is appropriate for the genre and desired by the client, while ensuring that the track retains clarity and dynamics (-14 LUFS to -6 LUFS).
How long does the mastering process take?
Depending on the number of tracks to be processed and the current workload, the mastering process can take between 2-5 days. However, I always work quickly and reliably to get your music back as soon as possible.
How can I be sure that my track is in good hands with you?
I am a professional sound engineer with over 12 years of experience, specializing in electronic music mastering. I work with professional equipment and plug-ins and deliver high quality results. You can also check out my customer reviews to see for yourself how satisfied I am.
Do you offer discounts for larger projects or regular clients?
Yes, I offer discounts for larger projects and regular clients. Please contact me for more information and to receive a custom quote.
Can I get a free sample of the mastering?
No, I do not offer a free sample of the mastering. However, you are welcome to listen to my previous work and decide if I am the right audio engineer for your project based on my client reviews.
