Step-by-Step Guide

  1. Add subtle tape saturation to your master bus at 5-10% wet. This adds overall glue and analog flavor.
  2. Apply tube or tape saturation to the drum bus for punch and cohesion. Keep it subtle (15-20% wet).
  3. Add tube saturation to lead vocals for warmth and presence. Use parallel saturation for aggressive passages.
  4. Apply light tape saturation to bass tracks. This adds harmonics that help bass translate on small speakers.
  5. Use transistor saturation on synths for edge and bite. Filter out harsh high harmonics if needed.
  6. Always evaluate saturation in the full mix, not solo. What sounds good solo may be too much in context.

Frequently Asked Questions

What is the difference between saturation and distortion?
Saturation is gentle, musical distortion that adds harmonics gradually. Distortion is more aggressive and can destroy the original tone. Saturation enhances; distortion transforms. In plugins, saturation typically has a softer knee and more gradual onset.
Can I use saturation on the master bus?
Yes, but keep it subtle. 5-15% wet is typical for master bus saturation. It adds glue and analog flavor. Too much master bus saturation makes the mix sound muddy and reduces transient punch.
Why does saturation make things sound louder?
Saturation adds harmonics that increase perceived loudness without increasing peak level. This is why saturated mixes often sound fuller and more present. It's also why saturation is used before compression for more aggressive loudness.
Should I saturate before or after EQ?
It depends. Saturate before EQ if you want to shape the added harmonics. Saturate after EQ if you want to add character to an already-shaped tone. For vocals, try EQ → saturation → compression. For drums, try saturation → EQ for more aggressive harmonics.
What is harmonic excitement?
Harmonic excitement is a type of saturation that specifically generates high-frequency harmonics. It adds air, brightness, and presence without raising the noise floor. Aphex Aural Exciter and Waves Aphex Vintage Aural Exciter are classic examples.
Can saturation fix a bad recording?
Saturation can mask some recording issues by adding character and warmth, but it cannot fix poor microphone placement, room acoustics, or performance. Use saturation to enhance good recordings, not rescue bad ones.
