Mastering

Who this service is for

Mastering fits when your mix is creatively settled and you mainly need loudness, finish and format compatibility. Solo artists releasing a single, labels sequencing a four-track EP, and producers aiming instrumentals at streaming all use this stage. Broadcast and video jobs also arrive when a final file must hit a specific loudness profile without reopening the mix.

If arrangement or level questions remain, book a mix session first or send rough stems for a quick opinion. We will say plainly when mastering would add little, for example on a demo still in flux. Spoken-word work such as podcast recording follows different workflows; we treat music mastering separately from speech finishing.

What to deliver

Supply your mix as an uncompressed file: WAV or AIFF, preferably 24-bit 48 kHz, with comfortable headroom on the mix bus. Include exact tempo and title, and note any fades or silence at the start or end. For albums, send track order and desired gaps or crossfades between songs.

Reference tracks are welcome as listening anchors, not mandatory. Avoid sending only an mp3 unless we agree that upfront for a quick check. Export guidance lives in mix delivery formats explained. If you are unsure about stems versus stereo mix, contact us before paying.

Room and workflow

Mastering runs in the control room on midfield monitors, away from the 38 m² live room. Daan Vermeer and Mira Jacobs alternate mastering depending on the calendar; you get one point of contact per project. We log target loudness, limiter choices and any per-track exceptions so the next single can sit in the same line.

We do not rely on one-size-fits-all automatic chains. We do use meters (integrated loudness, true peak) so platforms do not reject or normalize your release in a way that reshapes the mix. Vinyl cuts are discussed separately: sometimes a dedicated lacquer prep follows the digital master.

Streaming, vinyl and broadcast

For streaming we balance impact and dynamics, keeping true peak safely below clipping. Platforms normalize on their side; we deliver a master that survives that without surprise level jumps in a playlist. For vinyl we talk about side length, bass mono compatibility and how tight limiting may be.

Broadcast and corporate video often specify an LUFS target. Send the profile (for example -23 LUFS for many European broadcast chains) or your client brief. The table below is indicative; we align to your distribution channel.

Revisions and feedback

Each mastering project at Nazeriniedgevi includes up to 2 revision rounds based on reasoned feedback. One round means one set of updated masters or a clear note when a request would unintentionally alter the mix. Bundle comments in one email with timestamps or track names; phone calls are fine via 020 737 0284.

Extra rounds or stem rework sit outside the fixed price and are billed hourly or per song under our terms and conditions. We schedule revisions on weekdays where possible within Mon–Fri 10–20, Sat 11–18, depending on queue length.

Pricing, VAT and payment

Fixed rates for Mastering are listed below. Amounts include 21% VAT unless you invoice as a business with a valid NL887390869B01 number under our terms. Consumers usually pay a 40% deposit on confirmation; business clients may receive 14-day payment terms after delivery.

More than twelve titles on one album? Request a quote via contact or [email protected]. Cancellation is free up to 7 days before the planned start; after that, terms apply.

Delivery formats and archive

By default we supply 16-bit/44.1 kHz WAV for broad compatibility, plus 24-bit/48 kHz when you need it for video or high-res stores. HD variants on request. File names follow an agreed pattern (artist, title, ISRC if available) so aggregators do not scramble order.

We keep project files and masters for 6 months on secured storage, then delete unless you book an extension. Download within that window and keep your own backup. Intellectual property and usage are explained in mastering rights and delivery and our privacy policy.

What is not included

Mastering does not remix individual stems, tune vocals, edit beats or produce music from scratch. We do not distribute to Spotify, Apple Music or vinyl plants; you or your aggregator uploads the files we deliver. Multi-host podcast editing belongs under podcast recording, not music mastering.

If mastering reveals a technically troubled mix (clipping, severe phase issues), we pause and discuss: a short mix correction is sometimes cheaper than forcing the issue in mastering. That saves double spend later.

Visits and access

Most mastering is offline; you do not need to attend unless you want an attended session. To listen in person, book within Monday to Friday 10:00–20:00, Saturday 11:00–18:00, closed Sunday.. Address: Van Ostadestraat 184, 1072 AK Amsterdam (De Pijp). From De Pijp metro (North/South line) it is about a seven-minute walk via Ferdinand Bolstraat. Tram 12 stops at Ceintuurbaan, five minutes on foot to Van Ostadestraat. On-street parking is limited; use P+R at Zuid or Arena if you drive.

Lars de Vries coordinates scheduling; engineers handle technical mastering questions. See FAQ or all services if you combine mastering with tracking or mixing in the same week.
