Engineered Without Compromise

Psychoacoustic codec repair. Adaptive AI intelligence. Content-aware loudness maximization. Three shaping modes. 205 parameters of broadcast-grade processing.

Adaptive Perceptual Reconstruction

APRE is the first stage in the chain — a psychoacoustically-modeled engine that detects and repairs codec artifacts from lossy sources in real time. Transient restoration, SBR harmonic stabilization, stereo coherence repair, and micro-dynamic density recovery. No user controls needed — it listens and adapts.

  • 4-stage codec artifact repair (HE-AAC, AAC-LC)
  • SBR harmonic stabilizer to improve high-frequency coherence
  • Stereo coherence and micro-dynamic recovery

ProcIQ Supervisory Intelligence

ProcIQ performs real-time 8-band spectral analysis on every sample, deriving spectral centroid, tilt, flux, and energy ratios. It classifies content as Voice, Music, or Mixed, then applies bounded, smoothed offsets to every processing stage — adapting the entire chain before problems become audible.

  • Real-time scene classification with Neural Lite engine
  • Closed-loop effectiveness tracking (30% minimum floor)
  • Transparent telemetry with reasoning output

Loudness That Listens

MixBus Platinum doesn't just process — it pays attention. SmartBand EQ's adaptive 7th band corrects spectral tilt in real time. The TruePeak Limiter delivers brick-wall compliance with zero overshoot. And Clipper GX — the almost-magical final stage of the Shaping engine — pushes loudness to the edge with harmonic density that stays musical. Together, they form an active-aware system where every stage of loudness enhancement is driven by what the program actually needs.

  • SmartBand EQ with ProcIQ-driven adaptive HF correction
  • TruePeak Limiting with 48-tap Kaiser FIR precision
  • Clipper GX for high-fidelity loudness maximization
The Signal Chain

14 Stages. Absolute Precision.

Audio passes through each stage in strict serial order. ProcIQ supervises stages 5–12, applying bounded offsets in real time. All parameters are smoothed to prevent zipper noise.

    Two Worlds. One Processor.

    Built for Both. Settling on Neither.

    The same engine that powers world-class broadcast radio delivers stunning results on your master bus. No concessions, no trade-offs — just extraordinary sound.

    For Broadcasters

    The Standard in Broadcast Audio Processing

    MixBus Platinum is an ultra-powerful, high-precision audio processor engineered to help you deliver the world's best sounding broadcast radio. Four format-specific delivery modes with automatic pre-emphasis, overshoot protection, and stereo safety — so your station sounds louder, cleaner, and more present than the competition, every hour of every day.

    • Online, HD Radio, FM 75µs & FM 50µs delivery modes
    • APRE repairs codec artifacts before they reach your chain
    • BS.1770-4 LUFS metering for loudness compliance
    • ProcIQ intelligence adapts to voice, music & mixed content
    • Automatic stereo ratio limiting for FM safety
    For Producers

    Your Secret Weapon on the Master Bus

    The same low-latency, high-fidelity audio tools that broadcasters rely on to deliver world-class sound are a surprisingly powerful addition to your DAW's master bus. Drop MixBus Platinum on your final output and hear what 14 stages of broadcast-grade processing do to a mix. Try it as a final polish — you might never take it off.

    • Full 14-stage mastering chain in a single plugin
    • Three shaping modes from subtle warmth to assertive density
    • TruePeak limiting for streaming-ready masters
    • 0.5–5 ms latency — low enough for real-time mixing
    • Standalone app, AudioUnit & VST

    What Engineers Say

    Trusted by Professionals

    ★★★★★
    “We replaced an $8K hardware processor with MixBus Platinum and our listeners noticed — they said we sounded better. The Clipper alone is worth the price of admission.”
    JR
    James Rodriguez Chief Engineer, Metro FM
    ★★★★★
    “I use MixBus on every master now. The multiband compression is incredibly transparent, and the limiter gives me 2-3 dB more headroom than anything else I've tried.”

    Sarah Kim Mastering Engineer
    ★★★★★
    “The signal chain approach is genius. Having broadcast-grade processing as a single plugin insert changed my entire workflow. Nothing else comes close at this price.”
