C4 Multiband Compressor is a four-band dynamics plugin from Waves that applies compression, expansion, limiting or dynamic EQ to each frequency band. It also works as a four-band focusing equalizer when dynamics are bypassed.
Waves describes the C4 as a multiband processor that combines compression, expansion, limiting, dynamic EQ and standard EQ in one tool. Each of its four bands can run a different type of dynamics, so you can shape dynamics and tonal balance in the same plugin. The developer says the C4 adapts to the material it processes rather than being limited to a fixed set of functions.
Each of the four bands can run any type of dynamics processing, and you can mix different dynamics types across different frequency ranges in one session. This makes it possible to tighten a low band while leaving the top end more open, for example.
Bypass the dynamics and the C4 becomes a four-band focusing equalizer. Waves presents this as a way to use the same interface for straightforward tonal shaping when you do not need gain reduction.
You can choose a fixed release characteristic for each band or use Auto-Release Control, which the developer offers as an alternative to manual setting. Individual bands can be adjusted separately, or the master controls can change all bands together.
The Range control sets limits on how far the gain can move, so the processing stays within boundaries you define. This is useful when you want dynamics to act gently on a mix bus or a full track.

Yes. Bypassing the dynamics turns the C4 into a four-band focusing equalizer, according to Waves.
