AETHERN EQ-10

Graphic EQ workflow with flexible bandwidth control.

AETHERN EQ-10 is a JUCE-based equalizer plugin concept built around a familiar 10-band graphic EQ layout, with added bandwidth control through Q-mode. The project focuses on interface direction, plugin workflow, and fast access to practical tone-shaping controls.

The plugin brings the main tone-shaping controls into a compact interface, balancing fast visual scanning with enough depth for practical mixing and production workflows.

What it does

• 10-band EQ layout with dedicated input/output trim and HPF/LPF controls
• Q-mode workflow for bandwidth-focused editing
• Preset system with instrument-focused and mix-focused frequency layouts
• Clear bypass state and responsive visual feedback
• Interface concept designed around fast scanning and direct adjustment

Multi-band biquad EQ with switchable Q editing.

AETHERN EQ-10 is built in C++ with JUCE and uses a custom 10-band biquad structure. The first band runs as a low shelf, the final band as a high shelf, and the middle bands as peak filters.

The processor uses AudioProcessorValueTreeState for gain, Q-position, preset, trim, and bypass parameters. Presets define both the frequency layout and default Q behavior, while Q-mode lets the same 10-slider interface switch from gain editing to bandwidth adjustment.

Input and output gain are smoothed, filter values are clamped for safety, and the processor is structured around real-time parameter updates for responsive plugin control in a DAW environment.

Deeper control without crowding the interface.

One of the main design decisions in AETHERN EQ-10 is the switchable Q-mode. Instead of adding a second layer of always-visible controls, the same 10-slider layout can shift between gain adjustment and bandwidth editing.

This keeps the interface readable at a glance while still allowing more precise shaping when the user needs it.
