EQ or Compression First? Music Production Tutorial

Exploring the fundamental question of whether to apply EQ or compression first in music production, a common source of confusion for producers.

• Why certain processing orders are chosen • Examples of signal routing with EQ and compression • Different approaches depending on desired sound

The answer depends on what you're trying to achieve and the sound you're going for, not a universal rule.

• Increases or decreases energy at specific frequencies or frequency groups • Changes the distribution of frequency content in the signal • Can shift a sound from balanced to heavily mid-focused

• Controls dynamic range by reducing peak levels • Controls transients to make sounds spiky or smooth • Adds warmth and color with analogue-style compressors

EQ and compression are closely linked because the compressor acts on signal peaks, and EQ controls which frequencies contribute most to those peaks.

Uses threshold, ratio, attack, and release controls to reduce gain on peaks without showing which frequencies trigger compression.

• Provides graphical representation of which frequencies cause compression • Shows threshold in blue and effective gain reduction in yellow • Helps visualize which frequencies have the most energy

Compression reduces the gain of all frequencies equally when active, even if only certain frequencies trigger it, potentially suppressing desired elements.

The low-end rumble and a spike around 130-150 Hz were triggering excessive compression, reducing high-end and mid-range clarity.

Imbalanced frequency content before compression causes unwanted frequencies to trigger gain reduction on the entire signal.

• Use subtractive EQ before compression to balance the sound • High-pass filter to remove excessive low-end rumble • Make targeted cuts to problem frequencies

With pre-compression EQ, the compressor is triggered by high-end transients, mid-range tone, and balanced low-end together, resulting in more natural compression.

Some compressors like FG Stress include a high-pass detection module that ignores low-end when deciding compression, achieving similar results without EQ.

After subtractive EQ and compression, use additive EQ with analogue modeling to restore warmth and thickness lost during processing.

• Subtractive EQ to clean and balance • Compression to control dynamics • Additive EQ to warm and color

Different approaches work for different contexts, such as letting low-end trigger compression for indie rock guitar effects or keeping everything balanced for dense mixes.

Follow a clear vision: clean up the sound, control peaks, and warm it back up while listening carefully to achieve the desired result.
