Aurora Sirax Mastering Suite

Complete Mastering. Total Control.

SIRAX Mastering Suite by Aurora DSP is a powerful, modular mastering environment designed to take your music from the final mix to a polished, release-ready master.

Built around nine dedicated processing stages, SIRAX combines dynamics processing, precision equalization, stereo imaging, harmonic enhancement, clipping, limiting, and loudness optimization into one streamlined plugin.

Whether you're an experienced mastering engineer or an independent producer finishing your own tracks, SIRAX delivers the tools, flexibility, and visual feedback needed to make confident mastering decisions.

Nine Powerful Mastering Stages

• 1. GLUE — Bring Your Mix Together Create cohesion and consistency with versatile bus compression. Shape transients, fine-tune attack and release, apply sidechain filtering, and blend compressed and original signals for controlled, musical results.
• 2. SMOOTH — Control Harshness and Resonances Tame aggressive frequencies and unstable energy with four-band dynamic processing. Independent threshold, range, and focus controls help smooth problematic areas while preserving the character and clarity of your mix.
• 3. DYNAMICS — Shape Every Detail Take control of your master with advanced dynamics processing. Combine broadband and multiband compression, adaptive behavior, limiting, and parallel processing to balance punch, movement, and consistency.
• 4. EQ — Precision Tonal Sculpting Fine-tune your sound with a flexible 10-band equalizer. Adjust frequency, gain, Q, filter type, and slope to achieve the tonal balance your music deserves, from subtle mastering corrections to broad tonal shaping.
• 5. STEREO — Define Your Soundstage Control stereo width and spatial balance across frequency bands. Integrated correlation metering helps maintain a stable stereo image, allowing you to enhance spaciousness without sacrificing mono compatibility.
• 6. COLOR — Add Character and Harmonics Introduce warmth, density, and harmonic richness with selectable saturation models. Shape the amount of coloration while protecting low-frequency content from unwanted distortion.
• 7. CLIPPER — Maximize Impact Manage transients and increase perceived loudness before the final limiter. Choose between clipping curves and profiles, adjust drive and ceiling, and use oversampling and clip-reduction monitoring for precise peak control.
• 8. LIMITER — Final Level, Maximum Control Achieve competitive loudness with selectable limiting algorithms, adjustable ceiling and recovery behavior, gain-reduction monitoring, and true-peak protection. Final Edge shaping provides additional control over the finishing stage.
• 9. PUMPUP — The Final Touch Enhance perceived loudness, density, and presence after limiting. PumpUp provides the final stage of sonic refinement, helping your master achieve greater impact and energy.

Flexible Mastering Workflow

Every track is different, and your mastering chain should reflect that.

SIRAX allows you to freely reorder the first seven processing stages, adapting the signal flow to the needs of your material. Limiter and PumpUp remain at the end of the chain to maintain a consistent final processing structure.

All nine modules operate within one unified interface, reducing the need to manage multiple plugins and complicated routing setups.

Master Assistant

Need a starting point?

SIRAX includes an integrated Master Assistant that analyzes a section of your audio and proposes mastering settings.

Rather than taking control away from the engineer, the assistant provides suggestions that can be reviewed, modified, and applied according to your preferences.

Your music. Your decisions.
