Mastering creates a final opportunity for quality control  before your music is released, and in our DIY age of sole songwriters and producers, provides essential objective input. After all, it’s easy to lose objectivity while working on your own on a piece of music in your own studio.

What is Mastering?

Mastering is the final stage of audio engineering, following the recording and mixing production stages, immediately before manufacturing and distribution. It provides an opportunity to ensure all the tracks across an album sound balanced, creating a stylistic cohesion so that when played through, an album sounds like exactly that—a tightly-knit collection of related tracks, rather than a random assemblage of disparate elements. A well-mastered album will sound great on all formats, on all playback systems. Mastering is the crucial final step after you’ve gotten your final mixes together but before you start putting your music online or on CD. The purpose of mastering is threefold:
To create unity between the various tracks of a record and create a final product

To create unity between the various tracks of a record and create a final product. When you’re mastering a full record, you can have individual tracks/songs which were recorded in a wide array of different environments and perhaps even with different producers. At the very least, every song will be mixed down to different levels. It’s the mastering engineer’s job to create a unified flow and relation between the tracks which make up a record to turn it into that final product.

To make everything on the record sound as good as possible

To make everything on the record sound as good as possible. Tools like compression, limiters, and equalization can be applied to tracks to get the best possible sound even after the final mix has been handed over to the mastering engineer. Getting the best sound possible and overwhelming the client with quality is really the main objective.

To create the record itself and all that that entails

To create the record itself and all that that entails. This means nitty gritty things like setting how tracks flow into one another, the space between tracks, setting the overall output (volume) level of the CD to be on par with other commercial releases, making sure the CD adheres to RedBook standards, and even adding information to a CD like ISRC codes.

In short, the mastering engineer has a lot of responsibilities and because they are the last ones to touch a record before it gets sent off to the CD replication plant, everything has to be just right; otherwise it’s a costly mistake.

So what does a mastering engineer do?

A mastering engineer employs many techniques and processes during a session in order to achieve optimal results, maximising the track’s sonic potential. It is a combination of the skilful use of these processes, in conjunction with the engineers carefully honed hearing and professional experience, that makes the mastering process so effective.
Every project has unique requirements, but some of the more common processes utilised include:

To ensure every track is spectrally balanced, from sub-bass to treble, as well as creating a natural album-wide cohesion from track-to-track, so the album flows effortlessly.


To tie together the whole mix, bring out depth and detail, and occasionally rein-in unruly peaks.


To optimise track headroom, increasing the overall track level for a competitive loudness, limiting peaks without distortion or unduly affecting the track’s punch.
