The mix bus (or stereo output) should focus on 'global' enhancements that glue the individual tracks together and provide a final polish. The goal is subtle, collective processing—usually involving compression, EQ, and saturation—rather than fixing individual instrument problems.

What to do
  1. 1.Apply light 'Glue' Compression using a VCA or Mu-style compressor with a slow attack and auto-release to unify the dynamics of the track.
  2. 2.Use a broad-stroke EQ to add a subtle high-end 'air' shelf or a slight low-end bump to define the overall tonal balance.
  3. 3.Incorporate subtle Saturators or Tape Emulations to add harmonic complexity and round off harsh digital peaks.
  4. 4.Utilize a Stereo Imager or Mid-Side EQ to gently control the width and ensure the low-end remains centered.
Common mistakes
  • ×Avoid over-compressing; aim for no more than 1-2dB of gain reduction to prevent 'pumping' or loss of life.
  • ×Do not use heavy limiting on the mix bus if you plan to send the track to a professional mastering engineer.
  • ×Excessive low-end EQ on the bus can lead to phase issues or a muddy mix if not monitored carefully.
Pro tip

Always mix 'into' your bus processing from the start of the session rather than slapping it on at the end. This allows you to make mixing decisions based on how the processors react to your tracks.
