Mastering is the finalisation process where everything gets baked together. This is where the mix is perfected, and the track as a whole is worked on to give it shine, sparkle, volume, depth, punch and loudness.

During the mastering process, as audio engineers, we will typically utilise different tools like compression, stereo width tools, limiters, maximisers, EQ, automation and more to ensure that the final master achieves the right levels to meet industry standards and the proper tone for your style of music.

Mixing And Mastering: A Simple (But Complete) Guide


Mastering can indeed breathe life into a mix, but it's not a magic wand that can fix all issues. Some problems, like clipping, can't be eliminated entirely during mastering. Issues of EQ and panning can be patched up to some extent, but a mastering engineer can't separate individual tracks during an online mastering session. The key takeaway is that a clean, balanced mix, free from artifacts, gives your mastering engineer the best audio to work with. So, before you jump into mastering, ensure your mix is as polished as it can be. Remember, mastering is about enhancing a good mix, not fixing a bad one.

We aim to get a sound for the master that the artist and/or label are happy with in terms of their vision for the track, and that is technically correct, and this can sometimes be an iterative process.
