ABOUT

Acoustic simulation platform that generates synthetic audio data for training voice and sound AI models.

Treble develops software that simulates how sound behaves in physical spaces and turns those simulations into training data for audio AI. Developers model rooms, materials, devices, and ambient conditions as digital twins, then generate labeled training data and test edge cases without prototypes. The company reports its high-fidelity room-acoustic simulations cut median word error rate by up to 38 percent in multichannel speech enhancement tests. The Reykjavík-based company raised $18 million in September 2026 and offers a free trial.
