What it is

Dirac Live helps your sound system perform better in your room. It measures how your speakers and room affect the sound, then applies correction so music, movies and games sound clearer, more balanced and more precise.

Ideal for

Home Hi-Fi Audio Systems
Home Theatres
Music Studios

What it does

Our advanced software analyses how your room and speaker setup affect the interaction between sound waves and your space. By applying comprehensive corrections, it fixes any misalignment to improve clarity, imaging and balance.

The main benefits

  • Audio that sounds like the creator intended.
  • A more defined and aligned sweet spot for listening.

Key features

  • Impulse Response Correction

    Dirac Live adjusts volume levels and timing across frequencies. This ensures sound from all speakers is coherent, improving imaging and spatial detail.

  • Phase Alignment

    By aligning the phase of your speakers, all drivers and channels work together seamlessly, reducing distortion and smearing.

  • Multi-Position Measurement

    The system captures data from several positions to create a correction profile that improves the audio experience across the whole listening area.

  • Custom Target Curves

    Use built-in target curves or draw your own to explore personalised tuning of your system’s tonal balance.

  • Frequency Ranges and Channel Limits

    Dirac Live can correct either the full 20 Hz–20 kHz range, or when using a Limited Bandwidth license, focus only on the most problematic low-to-mid frequencies (up to 500 Hz).

    Dirac Live Processor for computer audio always applies full-range correction, but lets you choose between stereo and multichannel processing.

  • On-Device Filter Processing

    Once calculated, filters are applied directly on compatible devices for continuous correction with no added steps or latency. For non-compatible devices, see the desktop audio tool below.

The details

Where it runs

Dirac Live correction filters run directly on compatible audio devices (AVRs,
soundbars, streamers) after calibration.

For non-compatible devices, use our desktop audio tool to apply correction in real-time from your computer.

Check for compatibility

  • Setup

    1. Calibrate using the Dirac app

    Using a measurement microphone (such as the miniDSP UMIK-1) and the Dirac calibration software on your Windows/Mac computer or iOS/Android device, you'll measure your room from multiple listening positions.

    2. Generate correction filters

    The calibration software analyzes your measurements and creates custom correction filters tailored to your room and speakers.

    3. Apply filters

    For compatible devices: Filters are automatically uploaded to your device and run continuously during playback.

    For non-compatible devices: Use the desktop audio tool to apply filters in real-time to your desktop audio (standalone or DAW plugin).

  • Two options for playback

    Dirac Live Room Correction can be run:

    Directly from a compatible audio device: After calibrating, correction filters are uploaded to your device and run automatically during playback. No computer is needed after setup.

    As a desktop audio tool: For non-compatible devices, the desktop audio product applies correction in real-time to your computer audio (standalone app or DAW plugin). Speakers must be connected to your computer during playback.

  • Technical requirements

    All users:

    • Computer or mobile device for calibration tool (Windows 10+, macOS 11+, iOS, or Android)
    • External calibration microphone
    • A compatible device, or, if using the desktop audio tool, a computer with Windows 10+ or macOS 11+
