Treble Technologies, an Icelandic acoustic simulation company developing synthetic audio data and digital twin technology, has raised $18 million in funding to expand technology for audio-enabled devices and physical AI applications. Paladin Capital Group led the round, with participation from KOMPAS VC, Frumtak Ventures and the European Innovation Council Fund, bringing total funding to €36 million.
The investment will support expansion across consumer and enterprise audio products and physical AI, helping device manufacturers and AI developers train and test systems across simulated real-world acoustic environments.
Expanding Sound Capabilities for Physical AI
Treble develops acoustic simulation technology for intelligent systems that need to understand voice and sound across changing environments. Applications include wearables, head-worn devices, humanoid robots and autonomous vehicles. Treble has worked with companies including Amazon and Logitech on audio development.
“In many stages of developing Alexa as an AI assistant, we rely on virtual acoustic environments to accelerate product design and model development,” said Wontak Kim, Senior Audio Research Manager at Amazon. “Treble provides an accurate and scalable way to model those environments. It allows us to virtually assess audio quality and performance and evaluate scenarios that are difficult to reproduce through physical testing alone. Its platform and expertise have made Treble a trusted partner and a valuable extension of our team.”
"Logitech prides itself on delivering robust, immersive experiences for enterprise users. Treble allows us to accurately simulate complex acoustic environments that are difficult to reproduce or test at scale in the real world. Crucially, the fidelity of the underlying physics gives us confidence in those simulations, enabling stronger engineering conclusions and ultimately better-performing products,” said Andy Harper, Head of Audio AI and Signal Processing at Logitech.
Using Digital Twins to Accelerate Audio Development
Treble combines physics-based acoustic simulation, digital twins and synthetic data generation to recreate rooms, vehicles, devices, materials, speakers and background noise digitally. Development teams can generate labeled datasets, evaluate product configurations and test difficult acoustic scenarios without relying entirely on physical prototypes and recording programs.
The approach can reduce testing and data collection from months to days while supporting improvements in audio AI performance and product development.
“Audio and voice interaction is becoming a fundamental interface for the next generation of intelligent products, but the physical world is acoustically complex. AI models and devices that perform well in a laboratory can struggle when they encounter reverberation, background noise, or an unfamiliar physical environment. Treble gives development teams at the world’s leading device makers a faster and more scalable way to model those conditions, generate the data they need, and test products to ensure they work reliably in the environments where machines operate, and people interact with them.” - Dr. Finnur Pind, co-founder and CEO of Treble
Supporting Global Expansion
The new capital will help Treble expand the platform and address growing demand for acoustic intelligence in robotics and other physical AI systems.
“Paladin predicts that robotics will drive a profound wave of automation across the physical world. Yet today’s robots are largely limited to visual perception: they may detect what is in front of them but cannot interpret critical sounds - such as someone falling in another room or a crash around a corner. Even accurately understanding human speech remains difficult in real-world, acoustically complex environments,” said François Ruether, Vice President at Paladin Capital Group. “The Treble team has developed a simulation platform designed to help physical AI models and robots integrate visual and auditory inputs. This multimodal capability will be essential to making robots more useful, productive and safe in human environments. We are excited to support the company’s global expansion and to work alongside visionaries behind this differentiated approach to acoustic intelligence.”
