SATURATION AND DISTORTION

Adding harmonics by pushing a circuit or algorithm past clean. Small amounts read as loudness and warmth.

Key takeaways

  • Adding harmonics by pushing a circuit or algorithm past clean.
  • Small amounts read as loudness and warmth.
  • Even-order harmonics read as warmth, odd-order as edge, and both increase perceived loudness without increasing peak level — which is why saturation often does what a compressor cannot.
  • A touch of tape or tube saturation on a bass adds upper harmonics so it stays audible on phone speakers that cannot reproduce the fundamental.
  • Watch out: stacking saturation on every channel and the master.

Quick checklist

  • Can you define saturation and distortion in one sentence without looking?
  • Can you point at saturation and distortion in a real session, mix or contract?
  • Have you tried the practical move above at least once?
  • Would you catch the common mistake before it costs you a take?
  • Have you opened one of the primary sources below rather than a forum thread?

SATURATION AND DISTORTION IN DEPTH

Saturation adds harmonics by driving a circuit or algorithm past linear behaviour. Even-order harmonics read as warmth, odd-order as edge, and both increase perceived loudness without increasing peak level — which is why saturation often does what a compressor cannot.

How it works in practice

A touch of tape or tube saturation on a bass adds upper harmonics so it stays audible on phone speakers that cannot reproduce the fundamental.

The mistake people make

Stacking saturation on every channel and the master. Small amounts accumulate fast, and the result is a mix with no dynamic contrast left.

WHERE SATURATION AND DISTORTION SITS

Saturation and distortion belongs to mixing and mastering in the Sampled music glossary. The processing vocabulary, plus the loudness standards streaming services actually measure you against.

  • Universal Audio — analogue tone (opens in a new tab)

    Primary reference · uaudio.com

    “Adding harmonics by pushing a circuit or algorithm past clean.”— the claim this source supports

    Why it counts: Published by the organisation responsible for the thing being defined, so it is a first-hand source rather than a summary of one.

  • AES technical library (opens in a new tab)

    Professional standards body · Audio Engineering Society

    “Small amounts read as loudness and warmth.”— the claim this source supports

    Why it counts: AES writes and reviews the engineering standards and peer-reviewed papers this terminology comes from.
