This example illustrates the use of the binauralFIR node to spatialize in real-time an incoming monophonic audio stream around the head of the listener. The process can be easily replicated for multiple sources or multichannel audio streams. In this implementation, the binaural process simply relies on the convolution of the incoming audio stream with Head Related Impulse Responses (HRIRs) measured on a human head in free field conditions (anechoïc room). See  for implementation details and implementation alternative.
The basic user interface provides control of the rotation on the horizontal plane (azimuth) and on the vertical dimension (elevation). In the current version, the set of HRIRs is imposed. In a future release, the user interface will propose to download different sets of HRIRs from a public server that will host a database of individual HRIRs.
