The Signal Chain

How audio flows from source to your ears.

Signal chain = the order plugins process audio. Order changes everything.

// WHAT IT DOES

When you stack plugins on a track, audio flows through them in order — top to bottom in Live. EQ → processes the EQ-d signal through the . Swap the order and you get a totally different result.

Standard order on a vocal: → EQ → → compressor → /delay sends. Each plugin does its job on a cleaner input than the last.

Effects after the compressor change what gets compressed. Effects before don't. This is the most powerful and most-broken concept in mixing.

Think of it like → Signal chain is a cooking order. Salt before searing = different result than salt after.
▸ WHY YOU CARE
  • Plugin order is half the mix decision.
  • Same plugins, different order = different sound.
  • Knowing the order frees you from guessing.

Scenario 1/5 — Shared reverb on a return track
Classic Reverb Send
One reverb on a return is more CPU-efficient than 4 separate reverbs, and creates a cohesive 'room' that glues the mix.
GOAL: Set each send to approximately match the target levels. Press CHECK when ready.

▸ LISTEN FOR
  • Order changing perceived punch and clarity.
  • Pumping when time-based FX precede dynamics.
  • Saturation harmonics shaped differently when EQ comes after.
▸ WALKTHROUGH (5 steps)
  1. 1. DO: Add EQ then comp on a vocal.
    ▸ LISTEN: EQ shapes; comp evens dynamics.
  2. 2. DO: Swap order — comp then EQ.
    ▸ LISTEN: EQ now shapes the compressed signal — different result.
  3. 3. DO: Add a reverb and move it before vs after the comp.
    ▸ LISTEN: Before = comp pumps with reverb; after = reverb floats on top.
  4. 4. DO: Place an EQ before a compressor on a vocal.
    ▸ LISTEN: Compressor reacts to the EQ'd signal — less pumping on lows.
  5. 5. DO: Swap the order: compressor before EQ.
    ▸ LISTEN: Different result — neither is wrong, but they sound different.
▸ COMMON MISTAKES
  • Random plugin order without thinking.
  • Reverb before comp causing unwanted pumping.
  • EQing to fix problems that ordering would solve.
