Meridian

Meridian is a channel shaper built for tracks and group channels that need both surgical EQ and character. It combines a 5-band parametric EQ with variable frequencies, a soft-knee compressor, and analog-style saturation in a purpose-built signal flow.

Unlike traditional mixing chains that separate tonal shaping from dynamic control, Meridian uses an intentional hybrid approach: exciter before compressor, saturation after. The compressor reacts to the harmonics you create with the exciter — resulting in denser, more organic glue. Saturation then adds warmth on top, subtly coloring the already-shaped dynamics. The result is neither overprocessed nor sterile — just focused shaping that stacks intelligently.

Every move is visualized in real-time: a 1/3-octave-smoothed FFT spectrum shows your mix after processing, with an amber EQ-curve overlay displaying the exact effect of each band. Phase correlation and goniometer monitoring ensure your stereo image stays tight and intentional. Solo bands to isolate problem frequencies, and export your settings as a structured Markdown snapshot for AI-assisted feedback and iteration — this is mixing that shows its work.

Features:

• 5-band parametric EQ with variable frequencies (Bass, Lo-Mid, Mid, Hi-Mid, High).
• Per-band slope selection (A/B/C: gentle / medium / steep).
• Tilt EQ for tone shaping (±1.5 dB around 1 kHz pivot; warm/bright toggle).
• High-frequency exciter with harmonics-only saturation (placed BEFORE compressor).
• Soft-knee compressor (1.5–4.0:1 ratio, automatic knee, with GR envelope visualization).
• Parallel compression for transparent tone shaping (0–100% mix).
• Tube-style warmth saturation (DC-biased tanh, even harmonics — placed AFTER compressor).
• Global stereo width control (0–200%, L/R matrix).
• Real-time FFT spectrum (Blackman-Harris 4-term window, 1/3-octave smoothing).
• Amber EQ curve overlay showing exact band response.
• Stereo phase correlation meter and goniometer visualization.
• SNAP export — structured Markdown snapshot for AI feedback.
• Zero-latency processing with denormal protection.
