Real world audio is difficult to reproduce
Audio systems need to perform across changing environments, devices, and listening conditions. Physical recordings and lab tests take time to set up, while simplified simulations can miss acoustic effects that influence performance.
For engineering teams, that means gaps in training data, slow design iterations, and uncertainty about the situations they haven’t tested. Exploring a new idea or investigating an edge case often means another round of measurements or prototypes.
What Treble Enables
Bring in your device, configure the acoustic scene, and connect simulation to your development workflow. Explore designs, generate data, and evaluate performance with less reliance on physical prototypes and recording campaigns.
Real world acoustics
Simulate
Import device geometry, define microphones and sources, and configure your environment. Model how sound interacts with the design and, for wearables, the wearer before investing in physical hardware.
High fidelity data at scale
Generate
Vary acoustic conditions to create labelled datasets tailored to your device and use case, with detailed metadata. Cover scenarios and edge cases that are difficult to record at scale.
Benchmark & evaluate
Validate
Use the generated audio in your evaluation pipeline to test hardware and algorithms across repeatable scenarios. Understand where performance holds up and where it needs work.
