The Mixing Process

Once all the tracks are recorded, they will be mixed by the mixing engineers. The first step is to organize and name the tracks for easy identification.

Next, the gain plug-ins on each track are checked to ensure that no track is too loud, too quiet, or overpowering the others unless it is a deliberate choice. The mixing engineer then uses DAW faders to edit the levels for each track, pan them, and organize the workflow for a balanced output. This results in a first draft stereo file or rough mix that’s accessible via the Digital Audio Workstation.

The tracks then go through the EQ stage, where low-pass and high-pass filters achieve a better tonal balance for the mix. Compressors are applied to adjust the range of each track, while modulation, reverb, delay, and other effects can be added to individual tracks based on the desired sound.

Mixing involves editing, adjusting, experimenting, and tweaking until a good-sounding mix is achieved.

The Mastering Process

After the mixing process, the final step is mastering, which is crucial to ensure the quality of the mix is top-notch and ready for distribution on various platforms.

Mastering engineers are responsible for using several effects, such as EQs, stereo wideners, compressors, brickwall limiters, and linear phase EQs, to enhance the mix’s vibe and preparing it for radio play and mass distribution.

It is essential to understand that mastering is not about making drastic changes to the mix but refining and perfecting the details. It is not a fix for a poorly mixed track. Mastering involves minor tweaks and adjustments to ensure the mix sounds right.

When this process is applied to old tracks and released, it will result in a remastered track.

What Is the Difference Between The Mixing and Mastering Process?

Although mixing and mastering are sometimes used interchangeably, they are two distinct processes in the music production workflow.
