What Is a Mixing Engineer

Show table of contents

A mixing engineer is responsible for creating a final mix (a mixdown) of a musical piece. After the recording is completed, the mixing engineer blends all the tracks together using different processes and effects. Mix engineer is exactly the person who creates a cohesive song where all the parts work perfectly together.

What does a mixing engineer do?

Mixing a song is more of art than it may seem. Similar to painting, with all the experience and understanding of the rules, mixing engineers still have to create a new and unique music artwork each time. Knowing the trends of modern music and the sound quality standards is great, but not enough. So, what does a mixer do? Let’s dive deeper.


What Is a Mixing Engineer-photo 1The first and the biggest part of the work consists of listening. An engineer listens to the track and has to notice general impressions, big mistakes, and also tiny details. They have to have a trained and sharp musical ear to hear the slight differences in pitch, in the sound volume, and to be able to understand what sounds great and what doesn’t. And with all this listening process, mix engineers must not get tired and lose this sharpness of the musical ear, and still be very attentive and devoted to seeing the little things and the little parts of a complex composition they’re working on.



What Is a Mixing Engineer-photo 2When listening to the composition, the mixer has to dive deep into the meaning of the song, into its emotions and feelings, and have the idea of how to enhance that and how to make that more expressive and more obvious, more vivid in the song. He has to see, which themes and which lines in a son are the most important, and which should be in the background; what is the whole complex picture of this song and what is its main idea. This is like the work of a sculptor, to be able to shape the track.

The engineer needs to see the feelings and emotions of the songwriter and be able to understand them even if they don’t coincide with his own feelings and emotions. He has to be able to perceive, understand correctly, and reproduce the idea that was created by the artist. Together with understanding, mixing engineers must also be able to actually express it all correctly using the available audio tools and plugins.


What Is a Mixing Engineer-photo 3This job is usually done by the mixing engineer’s assistant. After the recording process is completed, there can remain some mistakes or little tiny details that should not be present in the final mix. Using the trained and sharp musical ear, the mixer or the assistant spots those parts and uses the right tools to eliminate those defects. Sometimes an engineer even does it manually, working with certain parts of the recording. It also can be pitch correction of a vocal part or some instrumental track.

On a bigger scale, some tracks like guitar part or kick, snare, or other instrument parts may catch mistakes on the recording level. Maybe the whole recording is somehow of low quality, and the mixer has to notice it and replace or correct it if possible.

Of course, we know, that recording mistakes are much better to be avoided on the recording level, and sometimes, mixing engineers can not help. But ther are mistakes that can be dealt with while mixing and this is what a good mix engineer will do.


What Is a Mixing Engineer-photo 4Mixing engineer understands what the track should sound like, and shapes it accordingly to receive the desired effect. The engineer determines how the track should sound, how dynamic it must be, what impression it brings, what emotion it conveys. Of course, vocals, instrumental parts, and the whole song idea have their impact, and how they all perform has a tremendous effect. However, the mixer brings to the song even more emotions, more atmosphere, more additional features, and beauty. This is the person who actually takes all the parts and makes the mix sound like one song.

The result should be an industry-level and highest-quality sound. All the elements are seamlessly united together like pieces of a puzzle, where you can not see them anymore as individuals, but as a complete picture, something really whole, something that by itself is a masterpiece

How one becomes a professional mixing engineer

What Is a Mixing Engineer-photo 5Of course, one has to study mixing, but only years of practice and genuine interest in the job can educate a professional audio engineer. This work requires having a passion for music in general, that’s why many great mixing engineers and producers own huge record collections.

And then tons of listening. Professional mixing engineers listen to music and learn from it. Music becomes his or her university, professor, and textbook. With studying and experience, a professional sound engineer learns how to understand sound and how to implement mixing ideas using available tools and gear.

How many hours does mixing engineer work?

What Is a Mixing Engineer-photo 6It all depends on the kind of work. Listening to a pretty loud mix is a dangerous task and to preserve good musical ears this can be done for no more than four hours a day.

However, if the engineer can work mixing at a medium volume level, longer hours can be allowed.

Also, during the day, mixing engineers have to do some other work with sound files and multitracks that doesn’t require listening to loud music. Of course, they can spend as much time on this type of work as they want.

The skills mixing engineers have

What Is a Mixing Engineer-photo 7Mixing engineers usually have a vast range of skills. They may have a background in music, and know quite a bit of everything in the field, starting from recording up to music production and distribution.

Mixing engineers may have expertise in the following areas:

  • Music theory. Educated mixing engineers have a solid understanding of music theory and have a trained musical ear. They can distinguish different harmonies and chords and know how a music piece is put together.
  •  Recording. They usually know recording pretty well, have skills in recording session musicians and know the best recording equipment. At the beginning of their career, many of them have worked as recording engineers.
  • Mixing in DAWs. Mixing engineers must know different DAWs, software, plug-ins and effects that are used for mixing music. They know well different audio formats and codecs as well.
  • Analog gear. Professionals can easily work with analog consoles and perform analog mixing as well.
  • Speaker set-ups. They know different speakers and playback devices. How to choose professional monitors, their qualities and set-ups.
  • Modern music and genres. Audio engineers should be well versed in the modern music and different music genres and trends. They should know up-to-date music quality standards of different genres. Their finger should be on the pulse of the modern music trends to watch for the latest news and technologies.
  • Physics of sound waves. This could sound strange, but mixing is all about the interaction of different sound waves within a recording, so your mixing engineer probably knows a lot more about the properties of sound waves than you do. They understand why you need to treat a studio for sound properly and how to do it. They also learn some physics to understand how analog gear and monitors work, and what their settings mean. A good audio engineer, of course.
  • Streaming and distribution. During their work, mixing engineers learn a lot about streaming platforms and song distribution in general. Each popular streaming service has slightly different requirements for music, and especially if a mixer does mastering as well, he or she knows these requirements and specifics. Professionals know and have worked with record labels and can advise you on how to get signed.
  • Mastering. Quite often, a mixing engineer is a mastering engineer as well. They should know different requirements for masters and can make a perfect master record for each streaming platform.
  • Music production. Usually, mixing engineers can create music themselves if needed in their studio.

    Looking for a High-Quality Sound for your song?

    Tools mixing engineers use

    What Is a Mixing Engineer-photo 8Mixing engineers can use analog gear and/or digital tools for mixing a track in their studio to produce the desired effect of the sound. Digital ( or in the box) mixing can be used in combination with analog mixing, in this case, the process will be called hybrid mixing.

    The important editing elements for in-the-box and hybrid mixing are the following plugins:

    • Different equalizers and filters, panning
    • delay-based plugins: reverb, delay, flanger, and others
    • different compressors, expanders, gates
    • saturation, distortion, fader, clipper
    • de-esser, de-noise, de-click
    • autotune, Melodyne
    • stereo expanders
    • and others.

    Each mixing engineer has their own favorite choice of plugins and way to use them.

    The goals of working with mixing engineer

    #2 – Eliminating problems. There are certain problems a mixing engineer has to eliminate in a track in the first place:

    • mess in the low end
    • sounds masking each other
    • clashing frequencies
    • and others

    #3 – Creating beauty. Aiming to create beautiful music, mixing engineers can do the following:

    • add various effects and processes like reverb, compression, and others
    • design stereo image
    • highlight the groove
    • Emphasize certain instruments or voices during certain periods of time, create the expressiveness and emotion of the song
    • Preserves the needed dynamic range
    • Balancing the mix

    But in addition, you may also ask for:

    • Mix in the form of multitrack
    • Alternative mixes like radio edit, instrumental version, or other
    • A master record also, if you were allowed to order mixing and mastering together

    How to recognize if the mixing engineer did a good job

    You need to listen closely to the mix. How do the vocals and individual recorded instruments sound? Carefully compare the mix with the reference tracks.

    Remember, before comparing you have to normalize the volume levels, make sure that your recording is the same volume as the reference track. Your reference track most probably is already mastered, and your mix is not. Subconsciously, we always feel that a louder mix is better. To remove this bias, make sure the tracks you are comparing are of similar volume.
