AI-Powered Room Optimization


Tailored acoustic engineering services.

Our Process

 In the pursuit of acoustic excellence, the journey is just as critical as the destination. At REDI Acoustics, we've refined a process that doesn't just solve acoustic problems — it anticipates them, providing you with a tailor-made solution that ensures your room is acoustically optimized from every angle. Whether you're designing a state-of-the-art recording studio or a high-end home theater, our process integrates science, technology, and real-world expertise.  Our specialized algorithms, NIRO and TORA, are powerful tools in our arsenal, but they are part of a larger, holistic approach to room acoustics design that is built on data, tested in theory, and proven in practice.   


 At the heart of any successful acoustic project lies a deep understanding of both the space and your specific needs. During the initial consultation, our team engages in a collaborative dialogue with you to lay down the acoustic goals and constraints for your room, setting the foundation for all the steps that follow.  The dual-phase approach allows us to tailor our algorithms and design principles to your environment with remarkable precision. 

Phase 1: NIRO

Phase 1: NIRO

Phase 1: NIRO

 For the NIRO phase, we require architectural drawings that detail the room geometry. Additionally, we need to know the specifications and quantity of the speakers you plan to use, as well as the desired listening positions. This information enables us to calibrate NIRO's algorithms to your room's unique characteristics. 

Phase 2: TORA

Phase 1: NIRO

Phase 1: NIRO

Once the NIRO phase is complete and its recommendations are integrated into the room design, we transition to the TORA phase. For this, we need to know the available treatment locations and areas within the room, as well as the depths at which treatments can be placed. This data ensures that TORA's optimization is aligned with the room's updated state post-NIRO.

What are we improving?

Room Modes and Standing Waves

Low-frequency Response and SBIR

Low-frequency Response and SBIR

Room modes play a pivotal role in shaping the room's sonic characteristics, especially at low frequencies. Uneven distribution of these modes can lead to problematic nulls in the frequency response at the critical listening positions. 

Low-frequency Response and SBIR

Low-frequency Response and SBIR

Low-frequency Response and SBIR

A balanced low-frequency response is key for the perceived sonic quality of a space. The placement of speakers directly influences the destructive interference caused by sound waves reflecting off nearby boundaries. This effect, known as Speaker-Boundary Interference Response (SBIR), heavily contributes to the low-frequency response at the listening position. 

Temporal Decay and RT60

Low-frequency Response and SBIR

Early Reflections and RFZ

Sound's behavior over time is captured by the room's temporal decay and the reverberation time (RT60).  While RT60 provides octave-filtered values of how long sound takes to decay by 60 dB in a room, the temporal decay spectrogram offers a detailed, frequency-specific visualization of sound decay over time. 

Early Reflections and RFZ

Early Reflections and RFZ

Early Reflections and RFZ

 Early, high-energy reflections can compromise the sonic image of a stereo system, particularly the phantom center. Managing these reflections and establishing a Reflection-Free Zone (RFZ) prevents frequency coloration and maintains audio clarity, which is crucial for critical listening. 

Reverberant Field

Early Reflections and RFZ

Industry Standards

The support and spaciousness of a room are significantly influenced by the behavior of its late reflections, known as the reverberant field. Ensuring this field is consistent across all frequencies, with diffuse reflections at specific angles minimizing ear-to-ear correlation, augments the immersive envelopment of sound in the room. 

Industry Standards

Early Reflections and RFZ

Industry Standards

In line with established industry metrics, our optimization strategies integrate the foundational standards of acoustic engineering and the insights from the latest psychoacoustical research. This synthesis ensures that our rooms not only meet recognized technical criteria but also resonate with the nuances of the human auditory experience. 

PHASE 1: ROOM GEOMETRY & POSITIONS OF SPEAKERS AND LISTENERS

Optimization with NIRO

 Embarking on Phase 1 of our process, the focus turns to the powerful Non-cuboid Iterative Room Optimizer (NIRO). Leveraging the data gathered during the initial consultation, NIRO employs multi-objective optimization algorithms to refine your room's acoustic properties. Specifically, it concentrates on optimizing the room's geometry and the positions of speakers and listeners to achieve several key objectives: 


  • Improved Low-Frequency Response: Enhance the clarity and presence of low frequencies for a more immersive listening experience.
  • Minimized Spatial Deviation: Establish a consistent sound field across the listening area, reducing the acoustic disparities that can distract from the listening experience.
  • Reduced Interfering Reflections: Target the Reflection-Free Zone (RFZ) to minimize distracting reflections, contributing to a cleaner, more focused soundstage.


 NIRO's optimization serves as the foundation upon which we build the subsequent phase, Treatment Optimization with TORA, ensuring a cohesive and holistic acoustic strategy from start to finish.  

PHASE 2: ACOUSTIC TREATMENT DESIGN

Why Our Process Matters

 Transitioning to Phase 2, our attention shifts to the innovative Treatment Optimization for Room Acoustics (TORA). Building on the foundation set by NIRO, TORA employs multi-objective optimization algorithms to further enhance your room's acoustics. This phase zeroes in on adjusting the locations and characteristics of various acoustic treatments in the room, aiming to achieve the following critical goals: 


  • Balanced Frequency Response: Achieve a consistent and balanced sound signature across the entire frequency spectrum.
  • Enhanced Low-Frequency Temporal Decay: Control the decay times of low frequencies to create a tight and articulate bass response.
  • Optimized Reverberation Time: Fine-tune the reverberation characteristics to match the room's intended purpose, whether it's for critical listening or live performances.


The TORA phase is vital for meeting industry metrics and standards, ensuring that your acoustic environment not only sounds good but also stands up to rigorous performance standards.

Documentation & Reporting

Upon the successful completion of the NIRO and TORA optimization phases, we assemble comprehensive documentation that serves as the guiding blueprint for your acoustic design. These reports are available in two formats:


  • Standard PDF Report: Includes detailed specifications, drawings, guidelines for optimal speaker and listener placement, a curated treatment plan, and a complete set of acoustic metrics in compliance with industry standards.


  • Interactive HTML Report: Features the same comprehensive data as the PDF but adds interactive plots for enhanced data visualization, allowing for a deeper understanding of the room's acoustic characteristics.


These documents act as a roadmap for architects, audio engineers, and contractors involved in the building or retrofitting process, ensuring a smooth and accurate implementation.
