Core Features of Bruel & Kjaer Dirac 3.0

Bruel & Kjaer Dirac 3.0 offers a comprehensive suite of measurement and analysis functions, all within a streamlined and user-friendly interface.

  • Comprehensive Room Acoustics Parameter Set
    Obtain a complete acoustic profile of any room. The software automatically calculates all essential ISO 3382 parameters, including Reverberation Time (T20, T30, EDT), Early Decay Time, Clarity (C50, C80), and Speech Transmission Index (STI).

  • High-Precision Impulse Response Measurement
    Capture accurate acoustic data using advanced MLS or Sine Sweep techniques. This forms the foundation for all subsequent analysis, ensuring reliable and repeatable measurements that meet international standards.

  • Intuitive Real-Time Analysis and Visualization
    See your results as you measure. Monitor key acoustic parameters in real-time during a measurement, and use detailed graphs and charts post-measurement to analyze and interpret the acoustic behavior of the space.

  • Sophisticated Auralization and Listening Tests
    Hear the impact of acoustic changes before they are built. The auralization feature allows you to convolve a “dry” audio signal with a measured impulse response, enabling subjective listening tests for design validation.

  • Detailed Reporting and Data Export
    Generate professional, customizable reports for clients and regulatory bodies. Easily export measurement data and graphs for further analysis in other applications, ensuring seamless integration into your broader project workflow.
