THE FINAL STAGE

A finished mix should feel finished everywhere.

Mastering isn’t about changing the identity of the track. It’s about making careful final decisions that help the music translate consistently beyond the studio. New to mastering? Read What Is Audio Mastering?

01

Balance

Tonal problems are refined so the spectrum feels controlled and the important parts of the mix remain clear.

02

Impact

Dynamics and level are shaped carefully so the track feels confident and competitive without simply crushing everything.

03

Translation

The master is considered as a complete record so it holds together across headphones, speakers, cars and larger systems.

MASTERING EXAMPLES

Different music. Same goal: translation.

From electronic music with dense low end to acoustic and guitar-driven productions, every mix needs a different mastering approach.

Listen for balance, low-end control, definition, depth and translation — not simply increased loudness.

01 HOUSE

House Mastering

Before and after mastering. Listen for low-end control, punch, clarity and a more cohesive finished balance.

02 TECHNO

Techno Mastering

Before and after mastering. Listen for weight, transient definition and greater control through the low and low-mid range.

03 DRUM & BASS

Drum & Bass Mastering

Before and after mastering. Listen for bass definition, impact and the relationship between the sub, drums and upper-frequency detail.

04 HIP HOP

Hip Hop Mastering

Before and after mastering. Listen for vocal presence, low-end balance and improved overall cohesion without flattening the groove.

05 ROCK

Rock Mastering

Before and after mastering. Listen for stronger separation, controlled density and greater impact while retaining the dynamics of the performance.

06 ACOUSTIC

Acoustic Mastering

Before and after mastering. Listen for natural tone, depth, vocal definition and a polished result that doesn’t sacrifice the dynamics of the recording.

Every track is approached as its own project rather than being pushed through a fixed processing chain.

01

START YOUR MASTER

Send me your pre-master.

Upload the finished mix, a reference track if you have one, and any useful notes about the sound you’re aiming for.

Upload Your Pre-Master

Please include your name and email address with the transfer. If you’re unsure about the mix first, send me a question.

PRE-MASTER CHECKLIST BEFORE YOU SEND
01
24-bit WAV or AIFF preferred

32-bit float is also fine. Avoid converting to a lower bit depth just for mastering.

02
Keep the native sample rate

If you mixed at 48 kHz or 96 kHz, send that. Don’t convert it to 44.1 kHz first.

03
Leave sensible headroom

A peak somewhere around -6 to -3 dBFS is a useful guide, but there is no magic target. The important thing is that the mix isn’t clipping.

04
Avoid final loudness limiting

Remove brickwall limiting or loudness maximising used only to make the mix loud.

05
Keep intentional mix-bus processing

If compression, EQ or saturation is fundamental to the sound of the mix, you don’t automatically need to remove it.

06
Include references and notes

A reference track and a short description of what you’re aiming for can be very useful.

Need more detail on export settings, headroom and final checks? Read the complete pre-master preparation guide.

01 Upload

I receive and check the pre-master.

02 Master

I work on the track and prepare the finished master.

03 Review

You receive a preview and can request one revision.

04 Pay & Download

I had my tune mastered at Product London and it was actually Kölsch’s demo of the month on BBC Radio 1.

Ross Fill Mastering Client
“

The tracks sound fab. They are loud and punchy yet still have great definition and separation.

Richard Mastering Client
“

Great communication, quick turnaround, attention to detail and, most importantly, the final product sounds great.

BEFORE MASTERING

Not completely happy with the mix yet?

Mastering can refine a finished mix, but it can’t replace the work that should happen inside the individual stems. If the balance, vocal, low end or arrangement still needs work, start with mixing instead.

FAQ

Mastering questions.

What file format should I send?+

A 24-bit WAV or AIFF is ideal. 32-bit float is also fine. Keep the file at the same sample rate used for your mix rather than converting it specifically for mastering.

How much headroom should I leave?+

There is no single required number. Roughly -6 to -3 dBFS peak is a useful guide, but the important thing is to avoid clipping or heavy final limiting.

Should I remove my master-bus processing?+

Not necessarily. If your bus compression, EQ or saturation is part of the sound of the mix, leave it. Remove processing being used purely to maximise final loudness. If you’re unsure, you can send both versions.

How long does mastering take?+

Most single tracks are sent for review within 2–3 business days. Larger EP and album projects may require a little longer.

When do I pay?+

You receive a preview first. Once you’re happy with the result, payment is made before the final downloadable master is released.

Are revisions included?+

Yes. One focused revision is included. If the issue requires changes to the original mix rather than the master, I’ll explain what I think needs addressing.

Do I need a separate Spotify or Apple Music master?+

For normal digital distribution you do not need to buy a separate mastering service for every streaming platform. The standard master is prepared for modern digital release.

Can you tell me if the mix isn’t ready for mastering?+

Yes. If I hear a problem that would be better fixed in the mix, I’ll tell you rather than trying to force a mastering solution onto it.
