Acousteer revolutionizes sound system design by offering an unprecedented level of live interaction at full-bandwidth resolution. Now, you can move virtual loudspeakers within your EASE 5 model and instantly see the impact on SPL coverage. This dynamic feedback loop allows for unparalleled experimentation and fine-tuning, empowering you to optimize system performance with precision. No more lengthy recalculations or guesswork – Acousteer puts the power of immediate visual feedback at your fingertips, making the design process more intuitive, efficient, and ultimately, more successful.
Interactive coverage optimization
Acousteer introduces a paradigm shift in acoustic modeling with its real-time mapping capabilities. It delivers instantaneous visual feedback by leveraging sophisticated CPU/GPU algorithms. The dynamic response to manipulating loudspeakers, DSP settings, and room parameters facilitates precise optimization of system coherence, coverage uniformity, and listening experience across the venue.
Full audio bandwidth
Acousteer offers low-frequency control by covering the full bandwidth from 20 Hz to 20 kHz. The interactive configuration of subwoofer setups and analysis of their radiation enables optimization of low-frequency coverage and elimination of unwanted cancellation effects. It empowers engineers to achieve an impactful bass response and an immersive listening experience across all frequencies.
Deeper understanding of the soundfield
Acousteer’s simulation engine breaks the limits with its high spectral resolution of more than 1/24 octave bands and the massive amount of up to 200 000 mapping data points that it can manage in real time. Explore the radiation pattern of your loudspeaker system in the greatest frequency detail. Identify local SPL hot spots and resolve problematic loudspeaker interaction anywhere in the venue. Take advantage of Acousteer’s resolution capabilities and get to learn about the sound field unlike ever before.
The future is interactive
Within just twelve months, Acousteer has evolved from a specialized real-time tool into a versatile simulation platform. Each update was a deliberate step toward a more holistic and integrated design process. Development began with interactive field analysis, followed by quantitative and temporal analyses and now continues with the integration of the room itself.
Steps towards fully interactive workflows
Acousteer is evolving into a comprehensive real-time acoustic simulation suite that will allow every aspect of a sound system's performance and its interaction with the listening room to be modeled, visualized, and optimized with an ease that was a dream just a year before. The boundaries between electro- and room acoustics in a real-time environment are blurring, and EASE 5’s Acousteer engine is setting the tone.
Sound Localization with Arrival Time Mapping
The Acousteer engine brings real-time psychoacoustic modeling to EASE 5 through its high-performance Arrival Time Mapping this feature moves beyond basic temporal arrival to incorporate Precedence Effect (Haas Effect) masking in a live, interactive environment. Users can instantly evaluate how SPL offsets and timing intervals interact, ensuring that localized imaging remains locked to the primary source. By dynamically calculating masking thresholds within the critical 50 ms window, the Acousteer engine allows for the immediate optimization of complex distributed systems to maintain total directional stability.
Acoustics parameters join the real-time loop
Identify the transition between wave and geometric acoustics with the integrated Schroeder Frequency display, and visualize the reverberant field as it dynamically interacts with the properties of your room materials. All with an expanded spectral bandwidth of 25 Hz to 20 kHz.
Total SPL, D/R Ratio, and SNR
The Acousteer engine further synchronizes electro-acoustic and room-acoustic analysis through a new suite of mapping functions, led by Total SPL—the real-time summation of direct sound and the reverberant field. This holistic approach allows you to evaluate the Direct-to-Reverberant Ratio (D/R) with surgical precision, visualizing the balance between the source and the room's energy across the full frequency range. By integrating environmental factors, the engine also facilitates the mapping of the Signal-to-Noise Ratio (SNR). These parameters interact dynamically with material changes and loudspeaker adjustments, ensuring that every design decision is backed by a complete, high-resolution picture of the acoustic environment.
Quantitative Insights: The Distribution Graph
The Distribution Graph provides an immediate statistical summary of the Acousteer engine’s high-resolution calculations, offering a real-time histogram that quantifies coverage uniformity across the venue. By analyzing the percentage occurrence for each user-defined result class, users can instantly assess performance using high-fidelity metrics such as level-weighted Average, Standard Deviation, and Max/Min values. Because the graph is derived from raw mapping data and updates dynamically with every project adjustment, it ensures that your acoustic designs meet the most rigorous standards for data integrity and spatial consistency.
