How to Prepare Your Mix for Mastering: A Practical Checklist for Independent Artists
You have spent weeks (or months) on the song. The beat hits, the vocal sits right, and the mix finally feels good. Then it goes off for mastering, and the engineer sends back a polite email: the file is clipped, there is no headroom, and could you send a new export? It happens far more often than you would think, and it is almost always avoidable.
Mastering is the final polish that makes your track translate on every system, from club speakers to phone speakers and streaming platforms. But a master can only be as good as the mix it is built from. This practical checklist from the team at Movinloud in Coventry will help you deliver a mix that gives your mastering engineer the best possible starting point.
1. Leave headroom, not loudness
One of the biggest myths in home production is that your mix should already sound loud before mastering. In reality, loudness is the mastering engineer's job. Your job is to deliver a clean, balanced, unclipped mix with room to breathe.
Aim for peaks around -6 dB to -3 dB on your stereo master channel. The exact number matters less than making sure nothing clips.
Remove the limiter or maximiser from your master bus before exporting. If it is part of the creative sound, send two versions: one with and one without.
Gain-stage your individual tracks so plug-ins are not being overloaded. Pull faders and clip gain down rather than pushing the master up.
2. Export in the right format
Your export settings can quietly make or break a master. Follow these basics every time:
Use WAV or AIFF. Never send an MP3 as your mastering source: the compression has already thrown away detail that cannot be recovered.
Export at 24-bit (or 32-bit float) and keep the same sample rate as your project, for example 44.1 kHz or 48 kHz. Do not upsample just for the sake of it.
Turn dither off when exporting at 24-bit. Dither is only needed when the final file is reduced to 16-bit.
Name your files clearly, such as ArtistName_SongTitle_Mix_v03.wav, so nothing gets mixed up.
3. Use reference tracks properly
Reference tracks are professionally released songs you compare your mix against. They are one of the quickest ways to spot problems with low end, vocal level or brightness. To get real value from them:
Pick two or three tracks in a similar genre, whether that is UK rap, drill, R&B, pop or afrobeats.
Drop them into your session and route them around your mix-bus processing.
Match the volume before comparing. A louder track will almost always sound better, which can trick you into making the wrong decisions.
Compare one thing at a time: kick and bass balance, vocal presence, stereo width, top-end sparkle.
It also helps to send your references to the mastering engineer with a short note on what you like about them. It gives them a clear idea of the direction you are aiming for.
4. Check your mix on more than one system
A mix that sounds incredible on your studio headphones might fall apart elsewhere. Before you hit export, listen on:
Your main monitors or headphones
Earbuds or AirPods, which is how most listeners will hear it
A phone speaker or Bluetooth speaker
A car stereo, if you can
Mono, to check that nothing disappears and the bass stays solid
If the vocal vanishes or the low end turns thin in mono, you may have a phase issue worth fixing before mastering.
5. Sending stems? Keep them aligned
Some projects benefit from stem mastering, where the engineer receives grouped sections such as drums, bass, instruments and vocals, alongside the stereo mix. If you go this route:
Start every stem at exactly the same point (bar 1 or the very start of the session) so they line up perfectly.
Export them all at the same sample rate and bit depth.
Keep effects, panning and automation printed, but avoid heavy limiting on any stem.
Include the full stereo mix as a reference so the engineer can check that everything sums correctly.
6. Final pre-flight checklist
Run through this quick list before you send your files:
No clipping on any channel, bus or the master
Clicks, pops and unwanted noise cleaned up
Fade-ins and fade-outs included where needed
Start and end of the file checked, with no clipped intros or chopped reverb tails
Alternate versions saved: instrumental, clean, vocal up and TV/performance versions if you need them
Song title, artist name, credits, track order and ISRC codes ready for release
Common mistakes to avoid
Mixing with a limiter on the master channel and forgetting to remove it
Trying to make the mix 'as loud as a commercial release' before mastering
Sending a low-quality bounce from a phone or video editor
Making last-minute changes to the mix after the mastering has started
