How it works

From Raw Tracks to Final Delivery.

You know what is happening at each stage: prep, mix decisions, revisions and delivery.

  1. Upload Your Tracks

    Send your stems as WAV at 48 kHz / 24-bit, or send the full DAW project when that makes more sense. Export from the project's start and label tracks by instrument.

  2. Reference & Brief

    Send references and a short brief: what should feel close, what should change, and where the current version is not working yet.

  3. Mix & Master

    Your project is mixed and mastered through a hybrid analog/software chain. Revision notes are handled before final delivery.

  4. Delivery

    Final files are delivered in the format agreed in the brief, from standard streaming delivery to high-resolution masters and Apple Digital Masters when requested. Typical turnaround is 2-10 weeks depending on scope.

Frequently asked

Questions Before Booking.

If something is not covered below, send a short message before ordering. It is better to confirm the scope before the files are in the queue.

Send me a message

I reply within one business day. Your details stay confidential.

What file format should I send you?

Export tracks as WAV at 48 kHz / 24-bit, starting from the project's beginning. MIDI tracks should also start at the same point. You can send your full DAW project or individual stems.

How should I prepare and organize my files?

Label every track clearly and group them into folders by instrument (Gtr, Drums, Synths, Vox, etc.). Include a reference track or a short note describing the sound direction you're after.

How many revisions are included?

Revision rounds are included before final delivery. The goal is to resolve clear mix or master notes properly, not to treat the project as a one-shot export.

What delivery formats do you support?

Delivery is tailored to your distribution. Standard 44.1 kHz / 16-bit WAV + MP3 for streaming, plus high-resolution masters (48 / 96 / 192 kHz, 24-bit) for video, hi-res platforms, and archival. Apple Digital Masters specification is supported on request - mastered to Apple's official spec and ready for streaming and archival at the highest available resolution.

How long does it take?

Turnaround depends on the package. Reamping is 2-3 weeks, analog mastering 3-5 weeks, full mix 5-7 weeks, mix + master 6-8 weeks, and editing + mix + master 8-10 weeks. You'll get a specific ETA once the scope is agreed.

Do you handle unreleased material confidentially?

Yes. Unreleased material is treated as strictly confidential by default. A mutual NDA is available on request - just let me know before I start.

How does payment work?

Payment is upfront via the secure methods available at checkout. Refunds are considered case-by-case only if work has not yet started - if there's no communication from your side for over three months, the project is closed and the refund right is forfeited.
