Mixing vs Mastering Explained

Mixing takes all the individual tracks of a song and balances them into one cohesive stereo mix. Mastering takes that finished stereo mix and prepares it for release, optimising loudness, tone, and consistency across a body of work and each delivery format.

They are separate creative and technical steps, usually done in that order, and most professional records go through both.

Mixing is where a recording becomes a song. The mix engineer balances levels so every element is heard, uses EQ to carve space so instruments do not fight, controls dynamics with compression, places elements across the stereo field, and adds depth and effects like reverb and delay.

A great mix serves the emotion of the song first. It makes the vocal sit right, the drums hit, the low end translate, and the whole thing move as one piece rather than a pile of separate tracks.

Mastering is the final step before release. The mastering engineer works on the finished stereo mix, optimising overall tone, loudness, dynamics, and stereo image so the record sounds its best on every system and holds up next to commercial releases.

On an album or EP, mastering also makes every track feel like part of one body of work, matching levels and tone and setting the spacing between songs.

Mixing and mastering solve different problems. A brilliant mix still benefits from the final polish, loudness optimisation, and format preparation that mastering provides. A great master cannot fix a mix where the vocal is buried or the low end is muddy.

Doing both, in order, is how you get a record that sounds intentional at every level and competitive on streaming, vinyl, and radio.

Streaming platforms normalise loudness, so chasing extreme loudness in mastering only costs you dynamics and punch. A good master sits competitively once normalised, sounding full and clean on Spotify, Apple Music, and YouTube without being crushed.

This is a mastering decision, not a mixing one, which is another reason the two stages stay separate.

It can work either way. Having one engineer mix and master keeps a single vision across the record and is efficient. Using a separate mastering engineer brings fresh ears to the final stage. We offer both together and separately, and we are happy to master a mix made elsewhere.

Whatever you choose, keep the roles clear: mix first, then master. Trying to master before the mix is finished, or to fix mix problems in mastering, leads to weaker results.

For mixing, deliver clean, well-organised stems or a tidy session, and share references. For mastering, deliver a finished mix with a little headroom and no master-bus limiting unless it is part of the sound.

Align on references before each stage. When everyone is aiming at the same target, both mixing and mastering get there faster and sound better.
