3D Audio

In the field of immersive audio, there are two main approaches for 3D audio rendering: headphones reproduction and loudspeakers reproduction. The first approach attempts to reproduce through headphones, at each eardrum of the listener, the sound pressure of virtual sources using head related transfer functions (Binaural synthesis and reproduction). In the second case, the binaural signal is delivered to the ears using two or more loudspeakers. In this case, the sound emitted from each loudspeaker is heard by both ears and a network of lters known as crosstalk canceller is usually adopted to avoid this problem.

The main topics are:

• Crosstalk Cancellation
• Binaural reproduction
• HRTF (Head Related Transfer Function) measurement
