Mastering and delivery
Your mix becomes a finished master suited to streaming, download and optional vinyl — with clear loudness, sensible sequencing and files you can upload straight away.

Mastering is the last listening pass before your music reaches a platform. At Miekpixel in Amsterdam we look beyond volume: balance between songs, transients, stereo image and how a track behaves after Spotify, Apple Music or Bandcamp normalisation.
You can send a mix made elsewhere or have us mix via mixing and editing. Offline mastering with written feedback is standard; if you want to listen in and decide on the spot, book a two-hour attended session in our 22 m² control room.
How it works
- 01
Brief
You send the mix, references and target platform. We confirm format, loudness goal and turnaround within 2 business days.
- 02
Analysis
We check headroom, clicks, silences and sequenced length. On EPs and albums we align track order and gaps.
- 03
Master
EQ, dynamics and limiting follow your genre and references. You receive a first master for review.
- 04
Delivery
After approval (and any revisions) you get final files plus a short delivery note explaining technical choices.
Who this is for
Mastering at Miekpixel suits solo artists, producers, labels and podcasters who want a consistent finish without maintaining an expensive mastering chain themselves. Singles due online within two weeks, three- to five-track EPs and albums where every transition matters — we work to your timeline within sensible planning.
Only stems from a home studio? Mixing is often the better first step; we prefer a mixed bounce with enough headroom. Unsure, send a short note via contact — we will say honestly whether mastering makes sense now.
What to deliver
Send your mix as uncompressed WAV or AIFF, ideally 24-bit 48 kHz (other sample rates are fine if you state them). One file per song, no master-bus limiter squashing everything. In your upload notes include title, ISRC if you have it, and two reference tracks whose loudness or tone you want to approach.
For EPs and albums: a text file with track order, desired gaps and any fade-outs. Instrumentals or clean edits are mastered at the same per-track rate unless we agree a bundle upfront.
- Mix without clipping on the master bus
- File name: artist — title — mix.wav
- References as streaming links or short WAV clips
- Vinyl plans if you need a cutting reference
Offline vs attended
Offline mastering means we work in the suite, send a first version and handle feedback by email or phone. That suits busy schedules and clients abroad who cannot travel to Amsterdam. 2 revision rounds on the same mix are included; extra rounds after you replace the mix are quoted separately.
Attended mastering (€165 for two hours) is for anyone who wants live decisions on EQ, punch and loudness. You sit in the control room, listen on our monitors and A/B against references. In that window we usually finish one or two tracks; a full EP in one attended block is rarely realistic — plan multiple sessions or combine offline work with a short attended check.
Loudness and platforms
Streaming services normalise playback; mastering louder rarely helps. We set integrated loudness and true peak for your distribution channel while keeping dynamics where the genre needs them. Our guide loudness targets for streaming explains the meters we use and why chasing maximum level is a dead end.
Download-only releases (Bandcamp, your own shop) can keep slightly more headroom. Vinyl reference masters are available on request: an extra file for your cutting engineer, not vinyl manufacturing — that is outside our service.
Formats and naming
Standard delivery:
| File | Typical use |
|---|---|
| 16-bit / 44.1 kHz WAV | CD master, many aggregators |
| 24-bit / 48 kHz WAV | Streaming and high-quality download |
| Instrumental / TV mix | On request, same mastering chain |
Files use clear names (artist — title — master) and sit on a secure download link. We keep project assets for 14 months; download and back up locally. Mix delivery formats are covered in bounce or stems for mixing.
Turnaround
A single track is usually mastered within five to seven business days after we receive a complete delivery and quote approval. EPs and busy periods may take longer; we give a concrete date. Rush is sometimes possible at extra cost if the calendar allows — ask via [email protected].
Studio hours: Monday to Friday 10:00–19:00, Saturday 11:00–17:00, closed Sunday. You do not need to be on site for offline mastering; attended sessions are booked within those hours via appointment.
Pricing and payment
All listed rates are consumer prices including 21% VAT. The per-track rate €82 applies to finished songs up to about six minutes; longer pieces are agreed upfront. The EP package €295 covers up to five tracks mastered as one batch. Net rates for business invoicing are available on request (€67.77 excl. VAT per track).
Booking requires a 35% deposit; the balance is due before we release final masters. Approved business accounts may pay within 21 days under our terms and conditions. Free cancellation up to 4 days before a scheduled attended session.
Not included
Mastering does not replace mixing: severe frequency clashes, spatial issues or vocal tuning are not fully fixable at the master stage. Remastering old cassette transfers without restoration is not our default — see mixing if cleanup is needed first.
Distribution to Spotify, copyright registration, artwork, metadata translation and vinyl pressing sit outside Mastering and delivery. We deliver files that meet common aggregator rules; you remain responsible for upload and rights.
Space and contact
Mastering is done by our mix and mastering engineer in the control room at Wibautstraat 224, 1097 DN Amsterdam. The room is set up for critical listening on full-range monitors; attended clients hear the same position we use during the session.

FAQ
Should my mix already sound loud?
No. Aim for 3 to 6 dB headroom on the master bus. Heavy limiting makes later mastering harder. If unsure, send a short clip via contact.
How many revisions can I request?
2 rounds on the same mix are included. If you upload a new mix afterwards, we charge for a new master or a smaller update fee depending on scope.
Do you supply DDP for CD?
On request we deliver a DDP image for professional CD replication at a small extra fee. Mention this when booking so we set sequenced gaps correctly from the start.
Can I listen in over video call?
Attended sessions expect you on site so you hear studio monitors. Remote listening is not a substitute for an attended slot; offline email feedback often works better at a distance.
What if my track is longer than six minutes?
Longer pieces such as live recordings or DJ mixes are quoted separately. Send length and genre; we reply within 2 business days with a proposal.
