Mastering is the last step of an audio project before it’s release. The purpose of mastering is to bring the audio content to the perfect balance, eventually add some color and optimize the release on all related systems and media formats. 

You can think of mastering as the last polish & quality check that optimizes playback quality on all devices (from little in-ears to high end audiophile monitors or huge club’s soundsystems).

Mastering helps to ensure listeners will hear – as most as possible – the sound as the artist meant it.

The name comes from the idea of a master print. Which is then used to make all copies/duplications of the project. Copis, which are then distribued under multiple formats such as streaming, digital download, CD, Vinyl, Tape etc…

Additionally, mastering is the place for the final quality check (QC) allowing to spot and fix the eventual clicks, pops, crackle or small issues that hadn’t be addressed in the final mix (or earlier).

Mastering is also the place to ensure consistency and uniformity of sound over the multiple tracks of a project. Bring a cohesive feeling to it.

Why master?

The goal of mastering is to ensure that your audio will sound the best it can on all platforms. Music has never been consumed on more formats and devices than today.
One of the other main aspect of mastering is also to have your track reviewed by a fresh pair of ears, still objective on the project.  Who, if needed, will fix the issues or enhance it using high grade tools carefully selected.

A good mastering job also makes an EP/Album consistent and balanced across all tracks. 

So what does mastering do?

Mastering is a complex process. Here are some of the techniques involved:


Fixing any small clicks, clips or other similar issues .

Ensuring a proper Stereo Image

Ensuring a proper Tonal balance

Ensuring a perfectly volume optimized & dynamics respectfull master with enhanced perceived loudness, definition in the hits, punch & tightness.

Ensuring optimisation for digital release following the codecs specifications of each platforms.

Ensuring best Sample Rate/Bit depth for distribution using high quality Resampling & Dither if needed.

Ensuring Metadatas are properly inserted in the final files using appriopriate tools.

Ensuring good sequencing & spacing between multiple  tracks in a same project.
