The Differences Between Mixing and Mastering in Music Engineering

If you’re a music enthusiast, you may have come across the terms “mixing” and “mastering.” These are two essential stages in music engineering that play a significant role in ensuring the final product is of high quality. However, some people tend to confuse the two or use the terms interchangeably. This article aims to differentiate between mixing and mastering, their significance in music engineering, and what each process entails.


Mixing and mastering are two fundamental stages of music production, but they serve different purposes. While they both focus on improving the sound quality of a track, they differ in the techniques, tools, and timing used. Understanding these differences is critical for anyone involved in music production, whether as a musician or sound engineer. So, let’s dive into what each process entails.

What is Mixing?

Mixing is the process of blending individual tracks together to create a cohesive sound. During mixing, a sound engineer combines different tracks that have been recorded separately into a final mix. These tracks could include drums, bass, guitar, vocals, and any other instruments used in the recording. The engineer’s goal is to balance each instrument’s sound to achieve a final mix that sounds pleasing to the ear.

Pre-mixing Preparation

Before starting the mixing process, the sound engineer needs to do some pre-mixing preparation. This involves setting the levels of each track to ensure they are all balanced, panning each track to create a stereo image, and applying equalization (EQ) to correct any tonal imbalances.

Mixing Techniques

Mixing is an art that requires the sound engineer to use their creativity and technical skills. Some of the techniques used in mixing include:

  • Balancing levels of each track
  • Panning tracks
  • Applying equalization
  • Adjusting dynamics using compression, limiting, and expansion
  • Adding effects such as reverb, delay, and chorus
  • Automating levels, panning, and effects to create dynamic changes throughout the song

The Importance of Mixing

Mixing plays a crucial role in music production because it determines the overall sound quality of the track. A well-mixed track will sound balanced, clear, and have all instruments sitting in the right place. On the other hand, a poorly mixed track will sound muddy, cluttered, and difficult to listen to.

What is Mastering?

Mastering is the process of preparing the final mix for distribution. During mastering, the sound engineer applies final touches to the track to ensure it sounds great on all playback systems, including radios, TVs, and streaming platforms. The goal is to make the track sound consistent and competitive in the market.

Pre-Mastering Preparation

Before mastering, the sound engineer needs to do some pre-mastering preparation. This involves listening to the final mix and correcting any issues that could affect the track’s sound quality during playback. Some of the things that the engineer can correct at this stage include:

  • Adjusting overall levels to ensure consistency throughout the track
  • Applying equalization to correct any tonal imbalances
  • Compressing the mix to control dynamics
  • Removing any unwanted noise such as clicks and pops

Mastering Techniques

Some of the techniques used in mastering include:

  • Applying stereo widening to create a wider sound image
  • Adjusting the overall EQ to ensure the track sounds great on all playback systems
  • Compressing the mix to ensure it sounds loud and consistent
  • Applying limiting to prevent any clipping or distortion during playback
  • Adding fades and crossfades to create seamless transitions between tracks
  • Creating a final master that is ready for distribution on all platforms

The Importance of Mastering

Mastering is critical in ensuring that the final mix sounds great on all playback systems. It also ensures that the track is competitive in the market, as it sounds professional and polished. Additionally, mastering can help to bring out certain elements of the mix that may have been buried during the mixing process.

The Differences Between Mixing and Mastering

While mixing and mastering both aim to improve the sound quality of a track, they serve different purposes, use different techniques, and occur at different stages in the production process.

The Purpose of Each Process

The purpose of mixing is to combine individual tracks into a cohesive sound, ensuring that all instruments are balanced and sound great together. The purpose of mastering is to prepare the final mix for distribution, ensuring that it sounds great on all playback systems and is competitive in the market.

The Timing of Each Process

Mixing occurs during the production process, usually after all individual tracks have been recorded. Mastering occurs after the final mix has been completed, and the track is ready for distribution.

The Techniques Used in Each Process

Mixing techniques focus on balancing individual tracks, panning them, applying EQ, and adjusting dynamics. Mastering techniques focus on adjusting the overall sound of the track, applying EQ and compression, and adding final touches to ensure it sounds great on all playback systems.

The Tools Used in Each Process

Mixing tools include a mixing console, EQ, compression, and effects processors. Mastering tools include mastering software, EQ, compression, and limiting processors.


In summary, mixing and mastering are both critical stages in music production that play different roles in improving the sound quality of a track. Mixing focuses on balancing individual tracks and creating a cohesive sound, while mastering focuses on preparing the final mix for distribution and ensuring it sounds great on all playback systems. Understanding the differences between mixing and mastering is important for anyone involved in music production.
