AirShape

AirShape is a premium high-frequency exciter and stereo widening plugin crafted by Plugin Nation.

Designed with a sleek, minimalist interface, it allows you to inject professional sheen, presence, and "air" into your mixes without ever adding harshness. It's the perfect secret weapon for vocals, synthesizers, drum overheads, or giving your master bus that expensive polish.

Features and Controls

1. BRIGHTNESS (Main Knob) This is the core of the plugin. Turning this knob increases the amount of harmonic saturation and high-frequency boost applied to your signal:

• How it works: Under the hood, AirShape uses a mathematically precise high-pass filter tuned at 7000 Hz to isolate the absolute highest frequencies (the "Air"). It then runs this signal through a custom Tanh waveshaper algorithm that generates lush, warm upper harmonics.
• Why it sounds great: By focusing only on frequencies above 7kHz, AirShape adds crystal-clear brightness without touching the critical mid-range or muddying up the low-end (like the punch of a kick drum).

2. SIDE EXPANDER (Bottom Knob) A powerful psychoacoustic stereo widening tool designed specifically for your high frequencies:

• How it works: When you turn this knob up, AirShape introduces a 20ms microscopic Haas delay exclusively to the generated high frequencies on the right channel.
• Mono to Stereo Magic: This technique tricks the human ear into perceiving a massive, immersive stereo field. The best part? It works magically even if your original sound is 100% mono.
• Mono Compatibility: Because the Side Expander only affects the extreme high frequencies (the "Air" saturation), the body and low-end of your track remain perfectly centered and mono-compatible.

Tips for Best Results:

• Vocals: Apply a gentle amount of Brightness (around 3 to 5) and push the Side Expander to 7 or 8. This will make the lead vocal sit perfectly in the center of the mix while the airy breathiness wraps beautifully around the listener's ears.
• Master Bus: A very subtle touch of Brightness (1 or 2) can lift a dull mix and give it that expensive, radio-ready polish.
• Synths & Leads: If your synth sounds flat or too mono, crank the Side Expander to instantly give it a wide, modern EDM/Pop character.
