Grav-LF

Grav-LF is a bass enhancement processor built around a dual-layer FFT analysis engine that monitors both input and output signals in real time. It focuses saturation strictly on the low end (30Hz-350Hz).

"Fully coded DSP & GUI — no images, no SVGs, no skins. Pure signal."

Demo Version Limitations:
• All saving and project recall features are disabled.
• 20-minute session limit. Simply reload (remove and re-insert) the plugin to reset the timer.

Key Features

• Engine: Dual-Layer FFT-Driven Bass Enhancement Processor.

• Modes: 7 selectable harmonic modes.

• Display Frequency Range: 20 Hz to 1000 Hz.

• Analyzer: Dual-Layer Dry/Wet FFT display for precise harmonic monitoring.

• FFT Engine: 4096 / 8192-point resolution with Blackman window.

• Response Model: Internal 4.5 dB tilt and 350 ms ballistic decay.

• Gain Structure:

- Drive: 0 to +24 dB.

- Output: -12 dB to +12 dB.

• Metering: Dual-layer LR Peak meters (background = input, top ticks = output).

• Interface Scaling: Runtime dual-sizing layout (Standard and Compact).

• Precision: 32-bit floating-point audio processing throughout the signal path.

• Sample Rates: Multi-rate support (44.1 kHz - 96 kHz), dynamically matching host DAW settings.

CPU-Efficient Processing

The DSP and GUI are written entirely in code—free of heavy images, SVGs, or skins. By eliminating graphic overhead at the source, this lightweight architecture ensures stable, low-latency processing that remains highly CPU-efficient, even under heavy analysis or at high sample rates.
