5 Pro Tips to Get the Best Results with Sonoris Multiband Compressor

How to Use Sonoris Multiband Compressor for Transparent MasteringMastering aims to enhance a final mix without changing its musical intent. The Sonoris Multiband Compressor (SMC) is designed to provide clean, precise multiband control with minimal artifacts — ideal when transparency is the goal. This guide walks through setup, band selection, parameter choices, workflow strategies, and troubleshooting so you can use SMC to tighten transients, tame resonances, and glue a track without pumping or coloration.

Why choose Sonoris Multiband Compressor for transparent mastering

• Transparent sound: SMC uses careful crossover design and linear-phase processing options to minimize phase issues and artifacts.
• Surgical control: Clear band routing and individual band controls let you address specific frequency problems without affecting the whole spectrum.
• Low latency and efficiency: Optimized CPU use makes it practical in mastering chains or DAW sessions with many tracks.
• Flexible metering: Precise gain-reduction and level meters help you make objective decisions.

Preparations before inserting SMC

1. Use a high-quality monitoring environment and reference tracks. Transparency is easier to judge on neutral monitors or accurate headphones.
2. Ensure your mix is well-balanced and peaks are at a reasonable level (typically -6 to -3 dBFS) so the compressor isn’t forced into extreme gain reduction.
3. Insert SMC near the end of the mastering chain — after corrective EQ but before final limiting — unless you need it for corrective duties earlier.

Recommended signal chain (typical)

• Corrective EQ (surgical cuts)
• Sonoris Multiband Compressor (transparent control and glue)
• Stereo widening / harmonic enhancers (if needed, use sparingly)
• Limiter (final loudness control)

Interface overview (key controls)

• Bands: SMC provides multiple bands (commonly 3–6). Each band has its own threshold, ratio, attack, release, and gain.
• Crossover points: Define the frequency boundaries between bands; linear-phase mode helps preserve phase coherence.
• Solo/Mute: Solo bands to hear the content within a specific frequency range.
• Sidechain: Per-band sidechain allows dynamics to be controlled from external or internal sources.
• Makeup gain: Individual and global gain compensation for transparent level matching.
• Metering: Input, output, and per-band gain-reduction meters are essential for objective monitoring.

Step-by-step mastering workflow with SMC

1. Start with unity gain: set global output to 0 dB and bypass makeup gain on bands. This avoids level-induced bias.
2. Listen in bypass vs. active: Frequently toggle bypass to ensure changes improve the track without unwanted color.
3. Choose crossover points: Start with broad bands — for example: Low (20–120 Hz), Low-Mid (120–800 Hz), High-Mid (800–5 kHz), High (5 kHz–20 kHz). Adjust to the material (bass instruments may need wider low bands). Use linear-phase mode if phase integrity is critical.
4. Set thresholds modestly: For transparent mastering, aim for gentle gain reduction — typically 1–3 dB on peaks, rarely more than 4–5 dB average. Lower the threshold until you see this amount of GR on loud passages.
5. Set ratios low: Use gentle ratios like 1.2:1 to 2:1 for glue and 2.5:1–4:1 only for more pronounced control. Avoid high ratios that aggressively pump.
6. Adjust attack & release per band:
   • Low band: Use slower attack (10–30 ms) to preserve punch, medium-slow release (100–300 ms) to avoid pumping.
   • Low-mid: Medium attack (5–15 ms) and medium release to control body without dulling.
   • High-mid / High: Faster attack (1–5 ms) and faster release (30–100 ms) to tame peaks and preserve clarity.
     Use program-dependent or auto-release if available for musical behavior.
7. Apply makeup gain carefully: Match output level to input so you’re comparing tonality, not loudness. A/B with matched loudness to judge transparency.
8. Use band solo and spectrum analysis: Solo bands to hear what you’re compressing — you might discover resonances or transient issues better addressed with narrow-band compression or corrective EQ.
9. Fine-tune crossover & thresholds: If a particular instrument or frequency range sounds squashed, shift crossover points slightly or reduce gain reduction in that band.
10. Check in context: Listen to the whole track and transitions (verse/chorus/bridge). Ensure the compressor behaves consistently across sections.
11. Automate if needed: For passages where uniform mastering compression doesn’t suit, consider automation (e.g., temporarily lowering threshold or bypassing SMC for dynamic sections).

Common goals & specific settings

• Tighten bass without losing punch

  • Low band threshold for 1–3 dB reduction, ratio ~1.5–2:1, attack 15–30 ms, release 150–300 ms.

• Reduce boxiness in low-mids

  • Focus on low-mid band 200–800 Hz, gentle ratio 1.5–2.5:1, faster attack ~5–10 ms, moderate release.

• Smooth midrange vocals/instruments

  • Mid bands: subtle gain reduction (1–2 dB), attack 3–10 ms, release 50–150 ms.

• Add clarity to high end without sibilance boost

  • High band: fast attack 1–3 ms, fast release 30–80 ms, gentle ratio 1.2–1.8:1. If sibilance appears, address with de-esser rather than boosting the band.

Transparency checklist (quick QA before export)

• Bypass comparison with matched loudness — ensure positive change without added color.
• Check mono compatibility — phase linear crossovers if needed.
• Listen at low and high volumes; quiet listening can reveal overcompression.
• Compare to reference tracks for tonality and dynamics.
• Inspect gain-reduction meters: consistent, small amounts are signs of transparent mastering.

Troubleshooting common artifacts

• Pumping or breathing: Increase release time on low band, widen crossover points, or reduce gain reduction.
• Loss of punch: Slow the attack on low frequencies to let transients through.
• Harshness: Reduce gain reduction in high-mid band or lower its threshold; consider surgical EQ instead.
• Phase-related thinness: Switch to linear-phase crossovers or adjust crossover frequencies.

When to avoid heavy multiband compression

• If the mix is poorly balanced: fix balance, panning, and EQ in the mix session rather than relying on mastering compression.
• For extreme dynamic preservation: acoustic or classical pieces often require minimal processing and transparent limiting instead.
• If you can achieve the result with EQ or automation: multiband compression is powerful but not always the best first choice for tonal fixes.

Example starting presets (templates)

• Clean Glue — 4 bands, broad crossovers, thresholds for 1–3 dB GR, ratios 1.2–1.8, linear-phase on.
• Bass Control — Emphasize low band control, slower attack/release, slightly higher ratio in low band.
• Vocal Smooth — Slightly increased gain reduction in mid band with faster attack/release for transient taming.

Final notes

Transparent mastering with Sonoris Multiband Compressor is about subtlety: small gain reductions, careful attack/release tailoring per band, and objective A/B testing with level-matching. Use SMC to correct and glue, not to reinvent the mix. When you’re done, finalize with a transparent limiter set to preserve dynamics while achieving target loudness.
