C4 Multiband Compressor

4-band multiband dynamics and equalization

Optimize Your Tracks with
Detailed Multiband Dynamics

The C4 blends an optimum combination of compression, expansion, limiting, dynamic EQ, and standard EQ to edit both dynamics and EQ with ease and accuracy. Whether you need to fix flaws, add intensity, or create character, this multi-purpose, time-tested tool is the answer.

Unlike multiband dynamics processors with rigidly defined capabilities, the C4 is a sonic chameleon that adapts its processing and functionality to your needs, and your tracks.

Apply any type of dynamics to each of the four bands
Bypass dynamics, and you have a four-band focusing equalizer
Mix and match dynamics control on different frequency bands
Choice of release characteristics, or Auto-Release Control
Control individual bands or all bands (master controls)
Unique Range control locks gain control action to limits you set

Double Down on Your Sound
by Editing Dynamics and EQ

De-Construct Mixed Drums
Take control over individual elements in drum loops and drum buses—limit the kick, tighten the toms with expansion, compress the highs, energize the snare with upward expansion—all while also EQing the drums.
Easy Editing of Your Dynamics
The C4’s Range parameter is a Waves exclusive. It defines the maximum amount of gain change (positive or negative), while Threshold sets where you want the gain change to start. Editing dynamics processors was never so easy.
Exceptional Equalization
The C4 is also a four-band equalizer with variable band frequencies and crossover slopes. The bands can be wide or narrow, and steep or gentle—and you can also add dynamics processing to any or all of them.
Choose Your Release
Choose the vintage-style, smooth release like optical compressors, or a release that accelerates as the audio decays for a quicker response. Or make it easy on yourself, and dial in the Auto-Release setting.
Artist Presets to Speed Your Workflow
Multiband processors have a reputation of taking time to edit, but with over 50 presets from pros like Dave Pensado, Ross Hogarth, Dave Aron, and Scott Gershin, the right sound is only a couple clicks away.
