• Pro Mode: Unconstrained parametric equalization with up to 16 filter nodes across 10 equal logarithmic frequency zones (20 Hz – 8,000 Hz) with live node inspection.

◆ 7 PROFESSIONAL FILTER TOPOLOGIES
Customize every individual node with precision filter algorithms:
• Peaking (PK / PEQ) with customizable Q resonance (0.1 to 10.0)
• Low-Shelf (LS) & High-Shelf (HS) smooth Butterworth curves
• High-Pass (HPF) & Low-Pass (LPF) 12 dB/octave cuts
• Surgical Notch / Band-Stop (NO) to eliminate harsh acoustic peaks
• Band-Pass (BP) filters

◆ AUDIOPHILE BIT-PERFECT & DAC INSPECTOR
• Direct AAudio Stream Binding: Optimized specifically for high-resolution external USB DACs with native sample rate detection (48 kHz, 96 kHz, 192 kHz+).
• Hardware Auto-Routing: Automatically detects connected audio outputs (Bluetooth A2DP, USB DAC, 3.5mm Headset, and Phone Speaker).
• Device Profile Auto-Switching: Bind custom EQ presets to your favorite headphones or car Bluetooth—Tonemorph automatically hot-swaps your sound profile when you connect.

• Bi-Directional Export: Export your custom EQ curves to share with friends or use on desktop audio setups.
