They strive to create a balanced mix, where all the elements of a song (vocals, instruments, synths, etc.) harmonize to create a cohesive sound.


A mastering engineer, on the other hand, comes in after the mixing process.


They take the final mix and enhance it, making minute adjustments to the sound’s overall EQ, compression, and stereo width.


The goal here is to ensure the track sounds polished and professional, no matter what device it’s played on.


Despite these being separate stages in music production, both mixing and mastering play crucial roles in shaping the final sound of a song or album.


  • The Mix engineer 一 Ensures all the musical components work together harmoniously, creating the song’s overall feel and emotional depth.
