Mastering is the final stage before a track is released. It is where the mix is checked, refined, and prepared to leave the studio properly.
That does not just mean making it louder. It means making sure the music feels finished, translates across different playback systems, and still holds onto the character of the mix. Tone, dynamics, balance, impact, and consistency all matter here.
For singles, mastering helps the track land the way it was meant to. For EPs and albums, it also helps the songs sit together as a body of work, with a consistent level, tone, and flow from start to finish.
Masters can be prepared for digital distribution, streaming, and CD release when needed. Single-track mastering is available, too.
Album mastering is about more than finishing each track on its own. It is also about how the release works as a whole.
That means paying attention to relative level, tonal flow, spacing between songs, sequencing, and the overall listening experience from start to finish. One track may need to feel more open, another more controlled, but the record still needs to feel cohesive.
The goal is to make sure each song stands on its own while still belonging to the release it is part of. For EPs and albums, that overall flow matters just as much as the sound of any single master.
Stem mastering is mastering with more access.
Instead of working from a single stereo mix, the music is delivered as a small number of grouped stereo stems. That allows more targeted adjustments without turning the process into a full remix.
For most projects, standard stereo mastering is the right choice and delivers excellent results. Stem mastering is useful when a mix is very close but needs a little more flexibility than a stereo file allows.
Typical stems might include drums, bass, music, vocals, and FX. The final goal stays the same: a finished, balanced, release-ready master that still feels like the record you made.
Mastering helps music translate.
A track might sound strong in the room where it was mixed, but that does not always mean it will hold up on headphones, in a car, on a home system, or in a club. Mastering is where those wider playback realities get taken seriously.
It also helps the music feel finished. That means better balance, better consistency, cleaner delivery, and a master that stands confidently alongside other releases without losing what makes the track yours.
Mastering is not there to reinvent the mix. It is there to help the music leave the studio in the strongest possible way.
Yes, if there is no other option, but it is not ideal.
A WAV or AIFF will always give better results because it preserves the full detail of the mix. MP3 is a lossy format, which means audio information has already been removed to reduce file size.
An MP3 can still be mastered, and the best possible result can still be aimed for, but the final master will always be limited by what is in the file. If a lossless version exists, that is always the better choice.
That is completely fine.
Some projects are straightforward, and some sit between services. If you are not sure whether a track needs standard mastering, stem mastering, lacquer cutting, restoration, or mix advice, just get in touch with the details of the project.
The best option is usually clear once the music and the goal are understood.
Preparing a mix for mastering is really about finishing the mix properly and leaving room for mastering to work.
A few things help straight away:
Make sure the mix is not clipping
Leave reasonable headroom instead of pushing the output into the ceiling
Avoid unnecessary master bus processing unless it is genuinely part of the sound
Export a clean, high-resolution stereo file
Listen through the bounced file before sending it
There is no single magic peak or LUFS number you need to hit before mastering. The important thing is that the mix is clean, intentional, and not already over-processed.

Turnaround depends on workload and on the type of project, but most standard mastering work is returned within 3 to 5 business days.
Stem mastering, restoration, and larger multi-track projects can take longer. If timing is important, it is always best to ask in advance.
Files can be uploaded securely using the upload link provided after checkout.
If you prefer to use a different transfer service, that is usually fine too, as long as the files arrive intact and clearly labelled.
Finished masters are delivered digitally, with links provided once the work is complete.
Finished masters are delivered in the formats needed for the release.
That might include WAV, AIFF, DDP for CD replication, or vinyl-ready files where relevant. If a release needs something specific, it is always best to mention that when ordering.
The goal is to make sure the final files are ready for the format they are meant for.
Yes. If something does not feel right, say so.
Revisions are part of making sure the master lands the way it should. Small adjustments are normal, especially once a track has been checked on different systems after delivery.
The aim is always to get the record where it needs to be, not to rush it out the door.
If a revision turns into a new mix, a new arrangement, or a substantially different version, it is usually treated as a new job rather than a revision.
Often, yes. Vinyl has physical limitations that digital formats do not. Side length, low-end behaviour, stereo information, and high-frequency content all affect how well a record can be cut and played back. A digital master may translate well to vinyl, but not always.
If vinyl is part of the release plan, a dedicated vinyl master is often the safest way to get the best result.
DDP is the standard format used when a release is heading to CD replication.
It is best thought of as the finished disc image of the release. That includes the audio, track order, spacing, PQ data, and any CD-Text or ISRC information that needs to be included.
Compared to sending an audio CD-R, a DDP set is more reliable, easier to verify, and preferred by replication plants. It can be delivered online, checked before manufacture, and verified with an MD5 checksum to confirm that nothing changed in transfer.
If you are replicating CDs, DDP is the format to use.
An untreated room pulls you off course.
When the frequency response of a room is uneven, what you hear is being shaped by the space as much as by the speakers. That makes it easy to over-correct problems that are not really in the mix, and miss problems that are.
It is not only a mixing issue either. If you record acoustic instruments or vocals in an uncontrolled room, the room becomes part of the recording. Sometimes that adds character. More often, it adds boxiness, ringing, or reflections that follow the recording everywhere.
If you want music that translates well and feels true to what you made, the room matters.
The best pre-mastering tip is to finish the mix properly before sending it off.
A mastering engineer wants to start with a clean, intentional mix rather than a file that has already been pushed into sounding “finished.” The goal is not to half-master the track beforehand. It is to give mastering room to work cleanly and make the right decisions.
That means paying attention to noise, headroom, export settings, mix bus processing, and final quality control before delivery.
Clean up noises, clicks, pops, and loose edits during the mix stage.
Anything left in the mix will usually become more obvious once EQ, compression, or level is added later. That can include bad fades, rough edit points, headphone bleed, lip noise, or tails that cut off awkwardly.
Getting rid of those distractions early helps the final master feel more polished and more intentional.
Do not over-process the master bus just to make the track feel more finished.
Heavy limiting, clipping, or excessive compression can flatten the mix and make mastering more constrained. If mix bus processing is genuinely part of the sound, it may belong there. But if it is only there to make the mix feel “mastered,” it is usually better left off.
A good rule is simple: keep what is truly part of the mix, and avoid what is only there to imitate the mastering stage.
If you are unsure, sending a version with and without the bus processing can help.
There is no single magic peak or LUFS number you need to hit before mastering.
The important thing is that your mix is clean, not clipping, and not being crushed on the output. Leave reasonable headroom so the mastering stage has room to work properly. A few dB of space below 0 dBFS is usually plenty, as long as the mix is not already pushed too hard.
If you are checking loudness, remember that LUFS and peak level are not the same thing. The goal is not to hit a target before mastering. The goal is to send a mix that is balanced, intentional, and still has room to move.
If you are unsure, err on the side of leaving more room, not less.
A proper loudness meter can be useful if you want to check LUFS and true peak before delivery (Youlean Loudness Meter).
For mastering, a clean stereo WAV or AIFF is usually the safest choice.
Both are lossless formats, which means they preserve the full detail of the mix and give mastering the best possible source to work from. Avoid sending MP3s unless there is no alternative.
It is also best to export at the original session sample rate and a high bit depth, rather than down-converting unnecessarily. If the mix was done at 24-bit / 96 kHz, send it that way unless your mastering engineer has asked for something else.
The cleaner the source, the cleaner the result.
Reference tracks are there for perspective, not imitation.
A good reference can help show whether your mix feels too dark, too bright, too bass-heavy, too vocal-forward, or simply off compared to the kind of record you are aiming for.
The important thing is to level-match your references as closely as possible when listening. Louder almost always sounds more exciting at first, so unlevelled comparisons can be misleading.
Good references help communicate the direction you want, not a target to copy exactly.
In addition to our standard mastering service, stem mastering is available when a project needs more control than a stereo file allows.
For most releases, standard stereo mastering delivers excellent results. But when a mix is close and still needs broader balance adjustments or more targeted control, stem mastering can be the cleaner option.
It offers more flexibility than stereo mastering without turning the process into a full mix revision.
Stem mastering works from grouped stereo stems instead of a single stereo mix.
That means separate files for broader parts of the track, such as drums, bass, music, vocals, or effects. Working this way allows more targeted moves to tone, levels, and dynamics than stereo mastering alone.
It is important to understand that stem mastering is not the same as full mixing. It sits somewhere between stereo mastering and a full mix revision, giving more control where the project needs it.
Preparing stems properly makes a big difference.
Stem mastering is useful when a stereo file is not enough. Instead of sending one stereo mix, you send a small number of grouped stereo stems so more targeted adjustments can be made. This gives more control over balance, tone, and dynamics without reopening the full mix session. To keep the cohesion of the original mix intact, we recommend sending no more than 8 stems per song.
When preparing stems:
Group similar instruments together into sensible larger parts such as drums, bass, music, vocals, FX, or synth groups
Export all stems at the same resolution
Make all stems the exact same length
Make sure every stem starts at the same point in the song
Leave headroom and avoid clipping
Remove unnecessary bus limiting or processing unless it is genuinely part of the sound
For most projects, stereo mastering is still the right choice. Stem mastering is best when a track needs a little more flexibility than standard mastering allows.
Lacquer cutting is where a recording becomes physical.
The audio is cut as grooves into a lacquer disc using a lathe. That lacquer is then used in the electroplating process to create the metal parts needed for vinyl pressing.
When ordering lacquer cutting, you can either have the music mastered here specifically for the cut or provide your own finished masters.
The lacquers are then sent directly to the pressing plant.
A dedicated master prepared here for the cut usually gives the best result.
Vinyl has physical limitations that digital formats do not. Side length, low-end behaviour, stereo information, and high-frequency content all affect how well a record can be cut and played back.
When the mastering and the lacquer cut are handled together, the music can be prepared specifically for the lathe, the side length, and the physical realities of vinyl. That gives the best chance of a cut that holds onto the energy of the record while respecting the format.
If you are supplying your own masters for lacquer cutting, a few things help straight away:
Send the highest-quality file available, ideally 24-bit lossless audio
Avoid digital clipping and extreme limiting
Keep the low end tight and controlled
Avoid excessive stereo width in the bass range
Watch for harsh sibilance and aggressive high hats
Be aware that longer sides usually involve more compromise in level and groove spacing
There is no single universal loudness target for vinyl. The important thing is that the music is clean, controlled, and prepared with the format in mind.
If in doubt, a dedicated vinyl master is the safest route.
