What Does a Mastering Engineer Do?

Creating music involves a series of steps that come before and after recording the song in the vocal booth. One very important step in the process of music-making is mastering the audio. Before any song is released onto platforms and distributed, the song, EP or album should go through a mastering engineer.

It seems to be more common knowledge what a music producer or even a sound engineer does but often, the objective of sending audio to a mastering engineer eludes most people so what does a mastering engineer actually do?

Early years

In the earlier years of music production, a mastering engineer’s role was to transfer master mixes to wax so they could be used for mass vinyl production and distribution. With rapid advancements in music technology, the functions of a mastering engineer go beyond just making wax masters.

Today, a mastering engineer is required to learn mastering techniques and skills that enable them polish and enhance tracks that form a song or an album to sounds great played from any source – whether it’s an iPod or a large speaker system.

Mastering audio to give it that refined and polished sound requires that the mastering engineers use a combination of analogue and digital tools to compress or limit sound, apply or adjust EQ, enhance stereo imagery and much more.

Without mastering audio, the volume across devices would vary, such that an audio mix might sound louder from one device to the next. A mastering engineer controls the overall volume thus ensuring that the music is played at a consistent volume via any playback device.

Fresh ears

The music-making process lends itself nicely to the idiom of ‘two heads are better than one’ when listening to a song. Keep in mind that when producing a song, the sound or mix engineer must listen to the same audio over and over again in order to perfect it.

This eventually makes it sound monotonous which by extension means the producer may not be able to make some necessary adjustments accurately. By sending your song to a mastering engineer, a valuable fresh set of ears would be listening to the song and as such make necessary adjustments.

Mastering engineers are also very good critiques because they are aware of the quality of sound the music should be at and so, therefore, are in a great position to help both the producer and music artist deliver the best sounding audio possible.

Mastering engineer responsibilities

During the process, the mastering engineer treats or enhances the necessary parts of the sound. Imperfections in production, mixing and recording are easily noticeable to the mastering engineer and as such need to be resolved before distribution.

In a nutshell, here is a bullet point of the functions of a mastering engineer.

  • Applies EQ, stereo imaging & limiting including final compression to the audio.
  • Balances the audio.
  • Chases the fade in’s and fade out’s in such a way that the digital silence is perfect
  • Processes every song in an album separately such that the volume of every song contained in the album is level.
  • Makes the required adjustments to the format that make the audio playable on all media
  • Removes glitches or  clicks that may have happened during the audio recording
  • Adjusts “spreads”: Spread is a term used to describe the time gap between songs.
  • Burns final master to send to the relevant client ready for mass production and distribution
