Mixing / mastering · London and online
Your song, finished properly
Professional mixing and mastering from a studio in Canary Wharf, London, and remotely for artists anywhere in the UK and worldwide. Send your stems and get back a release-ready record: balanced, tuned, polished and loud enough to sit next to anything on Spotify. £300 per song, mixed and mastered by an engineer with credits including Aitch, Not3s, Dappy, Sony Music and Def Jam.
What you get
Mixed and mastered, in one price
Most engineers charge for the mix and the master separately. At Choisez both are included at £300 per song, and you get a finished record rather than a stage in a process.
The difference
Mixing and mastering are not the same thing
A lot of artists pay for one and assume they got both. Here is what each stage actually does.
Mixing
Working with the individual parts of your song and balancing them against each other.
- Levels between vocal, beat and every layer
- EQ, compression and tone shaping per element
- Vocal tuning, timing and editing
- Reverb, delay and creative effects
- Stereo placement and space
Mastering
Working with the finished stereo mix as one piece, preparing it for release.
- Overall tone and final EQ
- Dynamics, glue and stereo width
- Loudness for streaming platforms
- Consistency across phones, cars and clubs
- Release-ready file delivery
You need both. A great mix that has not been mastered will sound quiet and unfinished next to commercial releases; a master applied to a weak mix cannot fix balance problems underneath it.
Credits
Mixed by someone whose work you have heard
Choisez has worked with Sony Music and Def Jam, and with UK and international artists. The engineer behind your mix trained in Music Production and Sound Engineering at SAE Institute London as the only scholarship student in his cohort, then spent years on professional analogue consoles.
An automated mastering service applies the same processing to every track it receives. A human engineer listens to your record, works to your references, and makes decisions specific to your voice and your genre.

Sending stems
How to send your song the right way
Getting your export right is the difference between a good mix and a great one. It takes five minutes and it matters more than any plugin.
- Export stems, not a bounce. Each element as its own audio file: instrumental (or its parts), lead vocal, doubles, harmonies, ad-libs.
- Start every file at zero. All stems must begin at the same point in the timeline so they line up instantly.
- Export dry. No reverb, delay, tuning or heavy processing baked in, unless an effect is the creative idea itself.
- Remove the master bus limiter. Anything crushing the mix on export limits what can be done afterwards.
- WAV, original sample rate. Keep the quality you recorded at rather than converting down.
- Send references. One or two commercial songs that sound like where you want to land.
Only have a two-track instrumental and a vocal? That works too. Send what you have and mention it in your notes.

The process
From your stems to a finished record
- Fill in the brief. Your name, artist name, contact details, genre, and notes on how you want the mix to feel.
- Send your stems. Upload the files directly, or paste a WeTransfer, Drive or Dropbox link if the session is large.
- Add your references. One or two commercial tracks that show the sound you are aiming at. This is the single most useful thing you can give an engineer.
- Pay securely online. Fixed price, taken through Stripe, so work can begin straight away.
- Review the mix. You hear it and raise anything you want adjusted before the master is finalised.
- Receive your master. Release-ready files delivered online, ready to upload to your distributor.
Good to know
Mixing and mastering: your questions, answered
How much does mixing and mastering cost in the UK?
Prices vary widely. Automated online services cost £10 to £30 per track but apply generic processing with no human judgement. Freelance engineers typically charge £80 to £250 per song, and established mix engineers charge considerably more. At Choisez Studio, mixing and mastering is £300 per song as a fixed price, handled by a human engineer with major-label credits, and includes both the mix and the master rather than charging separately.
What is the difference between mixing and mastering?
Mixing is the process of balancing the individual parts of your song against each other: levels, EQ, compression, tuning, reverb, delay and effects, so the vocal sits correctly against the instrumental and every element has its own space. Mastering is the final stage applied to the finished stereo mix, setting the overall tone, dynamics and loudness so the record translates consistently across streaming platforms, phones, cars and club systems. You need both, and both are included at Choisez Studio.
Do I need to be in London to get my song mixed and mastered?
No. Mixing and mastering is handled entirely remotely. You upload your stems or send a WeTransfer or Drive link along with your notes and reference tracks, and receive your finished, release-ready files online. Artists across the UK and internationally use the service without ever visiting the studio.
What files do I need to send for mixing?
Send your stems: each element of the song exported as a separate audio file, all starting from the same point in the timeline. That usually means the instrumental (or its individual parts), lead vocals, doubles, harmonies and ad-libs as separate files. WAV at the original session sample rate is ideal. If you only have a two-track instrumental and a vocal, that works too.
Should I export stems with or without effects?
Export them dry wherever possible, without reverb, delay, tuning or heavy processing baked in, so the mix engineer has full control. If a specific effect is part of the creative idea and the song does not work without it, keep that one and mention it in your notes. Always remove any master bus limiter or compressor before exporting.
Can you fix a badly recorded vocal?
A lot can be improved. Tuning, timing, balance, tone, sibilance and background noise can all be treated, and a mix can transform a rough recording. What cannot be undone is severe clipping, heavy room reverb recorded into the take, or distortion baked into the file. If the recording is beyond repair, we will tell you honestly rather than take the booking.
Will my track be loud enough for Spotify and Apple Music?
Yes. Every master is finished to streaming-ready loudness, balanced so it holds up next to commercial releases without being crushed by platform normalisation. The aim is a record that sounds full and competitive on Spotify, Apple Music, YouTube and TikTok as well as on phone speakers and in the car.
What genres do you mix?
Pop, R&B, Afrobeats, hip-hop, soul, alt pop, dark pop, indie, UK rap, drill, trap, Amapiano, Afroswing, dancehall, reggaeton, Latin, house and electronic and grime. Vocal-led music is the core strength, and the approach is always shaped by reference tracks you provide rather than a fixed house sound.
Do I own the rights to my mixed and mastered song?
Yes. Mixing and mastering does not affect ownership. The recording remains entirely yours and you are free to release it on Spotify, Apple Music, YouTube or anywhere else with no conditions.
Can I hear the mix before it is finished?
Yes. You receive the mix to review and can raise changes before the master is finalised, which is why reference tracks and clear notes at the start make a real difference to how quickly the record lands where you want it.
Do you offer recording as well as mixing?
Yes. If you have a beat but have not recorded yet, the £450 package covers vocal recording at the studio in Canary Wharf plus the full mix and master. If you want the instrumental made from scratch as well, exclusive production including recording, mixing and mastering is £1,990.
How do I send my stems and book?
Everything is handled online. Complete a short brief with your details, genre and notes for the mix, upload your stems or paste a WeTransfer or Drive link, then pay securely. Work begins once your files and payment are received.
