05 / Why Charlie
You've spent weeks on the mix. The arrangement is right, the elements sit where they should, and you're proud of it.
Now it needs the polish that takes it from "demo" to "release" — the part most producers either skip or hand to a $20 online service that runs your file through an AI and calls it a day.
Mastering is the difference between a track that gets skipped on Spotify and one that gets played out at festivals.
I master every Charlie Crown release with the same chain that's been on tracks released through Sony Music, Ultra, and Dim Mak — and played by The Chainsmokers, Martin Garrix, Steve Aoki, and Illenium. That same chain, on your track, hand-tuned to your sound.
Send me your final stereo mix. I send back a label-ready master in 4–5 days with the full deliverables package below. Don't love it? Unlimited revisions until you do.
06 / FAQ
4–5 business days from when I receive your final files. If you're on a deadline, mention it in the intake — I can often expedite.
Unlimited. The price covers however many rounds it takes to get it right. Most clients land at 1–2 revisions because the onboarding call clarifies the brief upfront.
Yes. I target current loudness standards (–9 to –14 LUFS depending on genre + brief) with intelligent limiting that preserves dynamics. Your master will translate across DSPs, club systems, and headphones.
I'll flag it upfront. If your mix needs work before mastering can help (muddy low end, narrow stereo, dynamics issues), I'll tell you on the onboarding call — and recommend either revising the mix or upgrading to the Full Mix + Master service.
24-bit WAV at 44.1 kHz or 48 kHz. -6 dBFS peak headroom. No master bus processing. Full prep checklist on this page.
After payment you'll receive an email with an intake form. Paste a Dropbox or Google Drive link to your file(s). No upload size limits.
If I can't deliver a master you're happy with after the first round + one revision, full refund. Unlimited revisions means we work until it's right — not until I get paid and disappear.
Verified client reviews
★★★★★
“Charlie took a super complicated song with many different elements and made the mix sound absolutely wonderful. We're electronic artists (The Keymakers) and have used a few engineers to try and bring out the best of our sound, and Charlie definitely killed it with this track. Would absolutely work with him again — amazing ear!”
★★★★★
“Charlie mixed a song for me and the end result was excellent, it sounds clean and well balanced. The process of working with him went very smoothly. He is very professional and I would recommend him 100% for mixing and mastering. Is incredible how Charlie can understand a project, and take it to a level where you never thought was possible.”
