Acoustic 3D Ray Tracing

Importing a 3D scene as an 'stl' file, obtaining the transfer func from point to any point within the scene and rendering the sound out.

An iPhone can be utilized to generate a 3D scan of a room, producing a file with an "stl" extension. These STL files can be imported into MATLAB®, where a sound source and microphone location can be designated within the 3D environment. The "acoustic room response" function released in 25a can provide an impulse response between the source and the microphone. Finally, a WAV file is processed through the response and render a simulated sound of what would be recorded from the specified location within the room.
