Automated mastering previews land in about 60 seconds and final masters inside 5 minutes. Stem mixing and Mix & Master bundles run 1–3 weeks. Full productions typically run 2–4 weeks.

Stem Mixing, Mix & Master and Standard human mastering include two rounds of revisions. Automated mastering lets you compare all preset previews before paying, then delivers the preset you choose.

Yes, we work across every stage, from first-release artists through to majors. Mastering and Mix & Master are often the right starting point; full production is scoped around what fits the artist.

Bounce all stems from the same start point and run them the full track length so reverb and delay tails sit correctly. Keep automation and effects intact. If you're using a master chain, send two versions: one with processing as reference and one clean. Use WAV or AIFF, 24-bit (unless discussed), at your session sample rate, with no normalisation.

Keep names short and isolate anything you're concerned about. A useful baseline: Kick, Snare, other Drums, Bass, Synths & Keys, Guitars, FX, and Vocals (dry and wet where possible). Test your stems in a fresh session before sending. Include a stereo reference mix of your track.

WAV, AIFF, FLAC and MP3 stereo mixes up to 500 MB and 15 minutes. MP3s are accepted with a lossy-source warning. A WAV or AIFF will always sound better.

Our readiness check flags clipping, severe limiting, bass-width problems and brightness issues before you pay. If your source isn't suitable for mastering, we'll point you to mixing, AI finishing or full production instead.

Each preset has a loudness goal — Club Hot is the loudest — but the final level adapts to your mix. Dense, club-ready mixes reach the full preset level; very dynamic mixes are delivered at the loudest level that stays clean, usually a little quieter, instead of being crushed to hit a number. Streaming platforms normalize playback to around -14 LUFS anyway, so this costs nothing on Spotify or Apple Music and your punch survives. When we adjust the level, the preview screen and report tell you exactly what we did and why.

Balanced is the clean default, Club is denser and louder, Club Hot pushes harder for DJ playback, and Warm is smoother while keeping the same release-ready level as Balanced.

A master isn't marked finished until it passes our checks: the right loudness, no clipping, the full length, and a clean file that opens properly. If we can't deliver one that passes, you get a refund or credit, and you never see the broken file.

Standard Mastering ($75) is our human lane: a senior engineer with two rounds of revisions and a detailed report. Album, EP and catalogue mastering are scoped per project; reference matching is on the roadmap.

It's automated, AI-assisted mastering, but tuned by engineers who play these tracks out, not left to a generic algorithm. That's the difference between a master that's just loud and one that actually sings on a system.

We focus on the six places AI drafts give themselves away: arrangement, sound selection, groove, stereo image, dynamics and mixing. We rebuild what needs rebuilding and leave what works. Every finish includes real mixing and mastering. No re-mastering of a compressed AI export.

We assess every draft for free before quoting. If a track has catastrophic timing drift, unrecoverable vocal artifacts or clearly infringing content, we'll say so, and point you to production instead.

No. Uploaded audio is never used to train models unless you explicitly opt in. Guest mastering previews are deleted after 72 hours; paid one-off masters have a 30-day redownload window.

Yes, our free AI Prompt Builder helps you write a stronger, more specific prompt under 1000 characters. It covers genre, energy, mood, groove, vocal type, era and instrumentation.

Automated mastering is charged at checkout, only after you've previewed the four masters. Mixing and finishing work (Stem Mix, Mix & Master, AI finishing) is payable up-front in full or 50/50. Full productions and ghost productions typically run 50% on brief, 50% on delivery.

No. There's no monthly plan and no account hoops to unlock your download, unlike a lot of online mastering services. You preview for free and pay once for the master you choose.

If a paid master fails verification, comes back corrupted or we can't deliver, you get an automatic refund or credit, no support ticket needed. Mixing, finishing and custom work is handled through the revision rounds in the booked scope, with case-by-case credit after a support review. Full policy on the refunds page.

You retain full ownership of your source and your master. We hold a limited licence to analyse, process, store and deliver your files. Ghost production work is scoped with either a buyout or a non-exclusive licence, explicitly agreed before we start.

Single-purchase automated masters are stored for 30 days. Mix and production project files are typically retained for 12 months. Ask if you need longer.
