Automated mastering previews land in about 60 seconds and final masters inside 5 minutes. Standard human mastering runs 48 hours. Stem mixing and Mix & Master bundles run 1–3 weeks. Full productions typically run 2–4 weeks.

Productized mixing and Standard human mastering include two rounds of revisions. Automated mastering includes one free rerender to a different preset within seven days of purchase.

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 route you into mixing, AI finishing or full production instead.

The target is built into the preset. Balanced and Warm render around -10 LUFS, while Club pushes louder at around -8.5 LUFS.

Balanced is the clean default, Club is denser and louder, and Warm is smoother while keeping the same release-ready level as Balanced.

Paid outputs aren't marked complete until they pass checks for LUFS, true peak, duration, channels, decode and checksum. If verification fails you get a rerender or a refund — you never see the bad output.

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

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 route you into production instead.

No. Uploaded audio is never used to train models unless you explicitly opt in. Guest mastering uploads are deleted after 72 hours; paid masters are retained per your plan.

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 three masters. Productized lanes (Stem Mix, Mix & Master, AI finishing) are payable up-front in full or 50/50. Full productions and ghost productions typically run 50% on brief, 50% on delivery.

Automated mastering includes a money-back guarantee when verification fails, the output is corrupted or we can’t deliver. For productized and custom work, dissatisfaction on otherwise-valid source gets a free rerender first and case-by-case credit after support review. Full policy on the refunds page.

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

Single-purchase automated masters are stored for 30 days. Creator Pack for 90 days, Pro/Label for 365 days. Productized mix and production project files are typically retained for 12 months. Ask if you need longer.
