Treble simulation of diffraction (RS6)

Abstract

Diffraction is a prominent low frequency phenomenon that is known to be difficult to simulate with traditional geometrical acoustics (GA) software even with some compensations. Treble outperforms the conventional GA software in simulating diffraction from a large barrier by directly solving the wave equation as shown in the BRAS (Benchmark for Room Acoustical Simulation) RS5 scene. This study compares Treble simulations and BRAS for the RS6 scene called finite diffracting body.
In this paper you can see how Treble's simulation validated against BRAS rs6 data on sound diffractions around a finite obstacle at low frequencies.

Synthetic realism in speech enhancement: Training models for the real world with ai-coustics

Tim Janke, Co-founder and Head of Research at ai-coustics, examines why voice AI systems struggle outside controlled environments and how training data is often the limiting factor. The article introduces synthetic realism as a data driven approach to teaching models what truly matters in real acoustic scenes, from distance and geometry to room acoustics. It also shows how physics based simulation with the Treble SDK enables spatially accurate training data that translates into more reliable speech enhancement and voice agent behavior in production.
