vaRays - live and ambisonic acoustical simulation

vaRays is a library for computing realtime Impulse Response for virtual acoustic of 3D environment.

vaRays loads an initial 3D model in which one or many sources can be created, moved and deleted, along with a controllable listener position. Controls are currently done by external software through a basic OSC protocol. vaRays then outputs in real time an impulse response file for each audio source, allowing the calculation of a convolution reverberation by an external software.
