Professional Mastering Services

Seattle-based, owner-operated mastering studio offering optional Apple Digital Masters, vinyl pre-masters, CD/DDPi, alternate versions, analog/tape processing, stem/restoration, and implementation-aware technical finalization for game, interactive audio, and film.

I offer professional stereo and stem mastering services from my owner-operated studio on Seattle’s Eastside, working with independent artists and labels worldwide. Deliverables are prepared for streaming, digital, vinyl, and CD release.

Singles / EPs / Albums

I master one song at a time, with the full project in mind for cohesion (when working on EPs and albums). I preserve what’s already working, then refine balance, impact, and tone so the record survives headphones, cars, headphones, and real speakers without losing its intent. I also work with podcast and live-session releases when the goal is platform-proof clarity: intelligible midrange, controlled peaks, consistent level, and clean delivery.

Sequencing and transitions

I can handle sequencing, spacing, fades, and transitions so the project plays as a coherent body of work, not a folder of unrelated files.

Deliverables

Every master is delivered in the formats you actually need, clearly labeled and ready to upload or hand off. I keep platform normalization targets for Spotify, Apple Music, and YouTube in mind, but I don’t let LUFS numbers dictate the work. The sound comes first.

Included with each song

  • 24-bit / native sample rate WAV master

  • 16-bit / 44.1 kHz (CD-quality) version

  • Reference MP3

Optional add-ons

Alternate mixes (instrumental / clean / a cappella, etc.)

If you need alternate versions delivered alongside the main mix, I can master those in the same formats so the whole release package stays consistent.

Apple Digital Masters

If you’re distributing to Apple Music and want the Apple Digital Masters deliverable, I can provide an optimized ADM file that meets Apple’s specifications.

Vinyl pre-masters

If you’re pressing to vinyl, I can provide dedicated pre-masters tailored to the format’s physical constraints, giving the cutting engineer an optimized, cut-friendly source for clean playback.

DDP (DDPi) production master

For compact disc releases, I can provide a DDPi production master — the preferred format for CD pressing plants — including your audio, track order, spacing, and metadata.

Analog / tape processing (by request)

Analog / tape processing is available by request for an additional fee.

Stem mastering and forensic restoration

When a project truly needs it, I also offer stem mastering and audio restoration. Most projects are best served by finishing the approved mix.

How it works

I keep the workflow simple so nothing gets lost and the process stays focused.

  1. Send your mix

    WAV/AIFF at the native sample rate (24-bit preferred). If you have references, include them.

  2. First pass

    Singles typically take 1–3 business days (often faster depending on workload). Albums take longer by nature — we’ll confirm timing up front.

  3. Revisions (included)

    Up to three revisions per track are included. Specific feedback is welcome — the goal is to help you land the record confidently.

  4. Final delivery

    You receive the final masters and any alternates, cleanly labeled and release-ready.

    Please credit clearly wherever you can (Mastering Engineer: Alexander Wright / Alexander Wright Mastering). And when it’s out, send the link and cover art so I can share it.

Rates and terms

I treat mastering as a craft, not a bulk service, so pricing stays consistent whether it’s one song or twenty. Albums aren’t discounted per track since achieving cohesion is a real aspect of this work. Very short pieces (intros/outros/interludes under a minute) can be priced lower. Full payment is required to secure your spot on the schedule before mastering begins.

  • Per song $140

    Includes the formats above, up to three revisions, and direct one-on-one communication.

  • Each alternate mix $35

    Instrumentals, clean edits, a cappella versions, etc. Delivered in the same three formats.

  • Apple Digital Masters (ADM) $100 (per project)

    Apple-optimized master files that meet specifications for Apple Music delivery.

  • Vinyl pre-master $100 (per side)

    Dedicated pre-masters tailored to vinyl cutting constraints for clean, cut-friendly playback.

  • DDP (DDPi) production master $70 (per project)

    Plant-ready CD master (DDP), including track order, spacing, and metadata.

A couple of important notes

  • Alternate versions should be submitted at the same time as the main mix. Late alternates are charged at the full mastering rate.

  • If you send an updated mix after I’ve started, that track becomes a remaster and is billed at 50% of the original rate.

  • I don’t offer free test masters. Instead, I provide level-matched before/after examples so you can hear the difference fairly.

Technical finalization (game / interactive / film)

I'm comfortable working with audio teams and technical deliverable requirements — clean specs, predictable files, defined turnaround. I've taken game design and game audio coursework, and I think in terms of playback context, implementation constraints, and how audio behaves in-engine.

For projects with approved content that needs a final pass before integration, I offer translation, loudness/DR calibration, asset polish, and QC informed by psychoacoustics and platform context. Not creative rework: finishing that holds up wherever the listener actually is.
