Mastering is the final breath your music takes before it meets the world—the moment where everything aligns, sharpens, and becomes undeniable.
This is where detail turns into impact. Where subtle adjustments unlock depth, clarity, and cohesion you didn’t know were waiting beneath the surface. Every frequency is refined, every dynamic carefully shaped, so your track translates effortlessly—from headphones in the dark to speakers that fill entire rooms.
We approach mastering as both precision and poetry. It’s not about making your music louder—it’s about making it felt. The low end gains weight without losing control. Highs shimmer without harshness. The entire mix opens up, balanced and alive, ready to carry your intent exactly as it was meant to be heard.
Whether your sound is cinematic, raw, electronic, or organic, we preserve its character while elevating its presence. Nothing is overdone. Nothing is left untouched.
Because mastering isn’t just the final step.
It’s the moment your music becomes timeless.

We prefer to work with .wav or .aiff files at a quality of 24bit - 44.1 Khz or higher. In the case high res. files aren't available it will depend on the quality of the files and the clients expectations before we decide to take on the job.
Export/print your mix with the same settings as your mix session. Name it "Artist/Band Name - Song Title".
Make sure that you didn't clip the stereo buss, and verify that you haven't cut anything off at the beginning and end of your song. (first note of an instrument, reverb/delay tails, etc...)
Make a folder and name it "Artist/Band Name - Song Title".
Add to the folder:
1. The exported/printed file of your song to be mastered.
2. At least 1 reference song in the same genre that has the sound and loudness you are after. (If you really can't get hold of the file(s) you can list the reference song(s) in the text file).
3. A text file containing: Song BPM, reference song title(s), and any additional important info, that you left out the intake survey, that can help us deliver exactly what you want.
If you are going to release your music on digital carriers (CD/USB/etc...), and want META - data embedded in the song file, you should also include the following in the text file:
Artist Name(s)
Songwriters Name(s)
Producers Name(s)
Composers Name(s)
Cover Art
ISRC (usisrc.org), NOTE: ISRC is Not mandatory.
ZIP/COMPRESS the folder. Name it "Receipt Number(mailed to you on purchase) - Artist/Band Name - Song Title".
Now you 're ready to upload the zipped/compressed archive file to [email protected] using a file sharing service of your choice.
High Res. Main Master (24bit - 48KHz .wav)
Main Master optimised for CD (16bit - 44,100KHz .wav)
Main Master optimised for streaming platforms (16bit - 44,1KHz & 24bit - 48KHz .wav)
Main Master MP3 (320kbps .mp3)
All submitted alternative versions (16bit - 44,1KHz & 24bit - 48KHz .wav)
With STEM mastering the mix is split up into busses (drums, bass, etc...). The benefit of working in this way is that the engineer has control over each individual STEM. Resulting in the engineer being able to process and balance each individual STEM correctly to get the very best from the song.
You should only order STEM mastering if you think the mix of your song isn't at it's very best yet, and you or your mix engineer can't get it any better... If the mix is really bad even STEM mastering can't safe it and you will need to have your song mixed properly first!
No, it is advised to remove all plugins you used to master your song. If you have plugins on your stereo buss where you mixed into since the start of the mix they are part of the mix and can definitely stay. Just make sure to remove the final limiter and everything you added after the mix!
Although this is NOT advised!!! If an mp3 is the highest quality file you have and you are unable to obtain a high resolution .wav file, we can work with it in a way that will still yield a better result. Off course it will be inferior than if you send us a high resolution file...
If there are any issues with the mix we will always contact you with suggestions on where to improve it before we continue with mastering.
If the mix is just not ready for mastering on many levels we will not proceed with mastering but suggest our mixing service or issue a full refund.
If you know that the mix of your song isn't exactly where it needs to be yet, and you want to improve it yourself but are stuck and need some guidance...You can order detailed (written) feedback on your mix. You can then use the guidelines to improve the mix before uploading for mastering.
