Instant Clarity.
The high-precision, ultra-visible audio analyzer for professionals.

Concept
In mixing and mastering, you don’t need endless menus and tweaking—you need to instantly and accurately see what is happening.
SOL-3 strips away the clutter to focus entirely on maximum visibility and strict measurement logic. It is the definitive minimal analyzer, designed to accelerate your visual decision-making.

Key Features
1. High-Resolution FFT with Selectable Window Size
Choose between three FFT window sizes to match your workflow — 2048, 4096, or 8192 points. The 8192-point mode far surpasses standard analyzers, delivering smooth, organic, analog-like waveforms from the lowest to the highest frequencies. It draws “true curves” without relying on artificial interpolation, showing you the exact energy balance of your track. Switch to 2048 points for faster transient response (~46ms), ideal for dynamic or percussive material.
2. Strict Compliance Metering
Fully compliant with the ITU-R BS.1770-4 standard. It calculates Integrated, Short-Term, and Momentary LUFS, as well as LRA (Loudness Range) in real-time—essential metrics for modern mastering.
3. Precision True Peak Detection
Features True Peak metering using 4x FIR oversampling. Prevent digital clipping and confidently monitor your audio to meet strict streaming platform standards (e.g., -1.0 dBTP).
- Warning Indicator (Yellow): Exceeding -1.0 dBTP
- Clip Indicator (Red): Exceeding 0 dBTP


4 Aesthetic Themes
Carefully selected color schemes reduce eye strain during long sessions while providing intuitive visual feedback.
- AQUA: A transparent, neutral reference color.
- FIRE: Maximizes visibility to instantly catch peaks and energy shifts.
- FOREST: Deep greens optimized for long mixing sessions, ensuring minimal eye fatigue.
- RAINBOW: Intuitively displays frequency distribution with color, helping you judge spectral balance fast.
