Spectra 99

SPECTRA 99 is designed for modern high-definition audio workflows and is fully optimized for sample rates up to 96 kHz, delivering precise and stable spectral analysis in both standard and high-resolution sessions. The VST3 plugin follows the host DAW's sample rate.

At its core is a 99-Band Balanced Log-Linear Musical Layout, providing a natural and intuitive view of your mix from deep sub-bass to the highest air frequencies.

Windows only.

Key Features

• Engine: 99-Band Balanced Log-Linear Musical Layout.

• Resolution: Adaptive 4096 / 8192-Point FFT.

• Windowing: Ultra-Low Spectral Leakage Blackman Algorithm.

• Tilt Modes: 0 dB, 3 dB, 4.5 dB Reference Slopes.

• Ballistics: 100 ms, 250 ms, 350 ms, 500 ms Decay Modes.

• Precision: 32-bit floating-point (Standalone), 64-bit double-precision (VST3).

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

• Stereo Tool: Correlation meter for width & phase monitoring.

• Safety: Output level control (Standalone).
