Treble Case Study
Market: CAE
With Spatial, we’ve seen clear improvements in mesh quality and data handling, which has made our simulations more reliable and streamlined the workflow. The biggest gain has been in volumetric meshing, where we estimate a 20–30% improvement in simulation efficiency.
The Company
Treble Technologies redefines the future of sound through state-of-the-art acoustic simulation and spatial audio solutions. The company’s impressive products provide advanced acoustic simulation, spatial audio rendering, and synthetic audio data generation. Treble’s mission is to make the world a better-sounding place by equipping professionals with the most accurate, scalable, and efficient sound simulation tools.
Since 2020, Treble has rapidly scaled its technological footprint, establishing partnerships with leading global tech firms and driving adoption across key verticals where precision audio is mission-critical. Treble’s technology leverages a hybrid wave-based and geometrical acoustics engine that delivers unprecedented accuracy across a wide frequency spectrum.
Trebble serves acoustic engineers in the building industry and professionals in the pro audio sector—including venue designers and manufacturers of audio equipment. They also collaborate with industry leaders like L-Acoustics.
Their flagship products are the Treble Web Application, a cloud-native environment for acoustic simulation and auralization, and the Treble SDK, a Python-based development kit that enables scalable simulations, synthetic data generation, and seamless integration into R&D and machine learning pipelines.
Treble Web Application
The Treble Web Application is the industry's first cloud-native simulation platform for room and product acoustics, purpose-built to align with modern architectural and engineering workflows. It integrates a wave-based finite element solver and geometrical acoustics into a seamless hybrid engine, delivering full-spectrum simulation fidelity. Designed for professionals in the built environment, the platform enables rapid, high-accuracy simulation of complex environments.
Treble SDK
The Treble SDK is a Python-based programmatic interface to Treble’s high-fidelity acoustic simulation engine, designed for scale, speed, and seamless integration. It is engineered for advanced R&D, audio algorithm development, and synthetic data generation. Leading global tech companies use the Treble SDK to set the benchmark for scalable, physics-accurate audio data generation and analysis.
Leveraging Treble’s proprietary hybrid simulation core engine, the SDK delivers wave-accurate and high-fidelity monaural and spatial impulse responses with up to 32nd-order ambisonics. It supports thousands of simulations in parallel, enabling robust machine learning pipelines, virtual prototyping, and automated parametric design.
The Challenge
Saving Data Preparation Time with Automatic 3D Meshing
To understand Treble’s application needs, it is helpful first to understand the workflow.
Using the Treble Web Application, users begin by importing a 3D model of a room or space via IFC, SketchUp, or other standard formats. Within the web app, they can place sound sources and receivers, assign acoustic materials to surfaces, and configure simulation parameters. From there, the system automatically handles geometry processing, meshing, and acoustic simulation using our proprietary solver. The results can then be rendered, analyzed, and shared instantly with collaborators through simple web links. The entire workflow is browser-based, with no local installation or specialized hardware required.
In the Treble SDK, users define acoustic scenes via code, specifying geometry, materials, source, and receiver configurations, and trigger simulations through a Python API. The SDK handles geometry preprocessing, meshing, solving, and output generation in the cloud.
Treble came to Spatial for industry-proven meshing components. They needed a solution that could generate surface and volumetric meshes on which to run simulations. Spatial’s 3D Precise Mesh fit the bill perfectly.
Key Insights
Marked Improvement in Simulation Efficiency
Before integrating Spatial SDKs, Treble relied on open-source mesh generation tools, many of which stemmed from academic research. These solutions often lacked robustness and required significant manual handling. With Spatial, Treble has experienced clear improvements in mesh quality and data handling, making their simulations more reliable and the workflow more streamlined.
Simulation efficiency is critical for Treble’s customers, many of whom operate in fast-paced design environments where quick iteration is essential. The most significant gain since integrating 3D Precise Mesh has been in volumetric meshing, where Treble estimates up to 30% improvement in simulation efficiency. This has allowed them to run more simulations in less time and reduced the need for manual adjustments. It also helps reduce the operational overhead associated with simulation setup and troubleshooting. This performance boost has become a meaningful differentiator for Treble’s platform in a market where accuracy and turnaround time are key. Overall, the integration has made their simulation pipeline more stable and easier to scale.
Spatial’s SDK helps Treble focus on its main value proposition: efficiently performing acoustic simulations at scale.
