Binaural Spatial Audio

Work­ing under KVS Hari at the Indian Insti­tute of Sci­ence (IISc) as a sum­mer intern, I had the oppor­tu­nity to explore bin­au­ral spa­tial audio. This was my first expe­ri­ence with spa­tial audio and Head Related Trans­fer Func­tions (HRTF’s), which I used in a few of my later projects.

Using the data­base of HRTF’s from the MIT Media Lab, I worked on gen­er­at­ing vir­tual sources of sound and gen­er­at­ing spa­tial sequences. I also used spline inter­po­la­tions to cre­ate a ‘rotary’ effect, where the source of the sound appears to revolve around the lis­tener. Finally, I worked on cre­at­ing a ‘spa­tial mix’ of audio from a multi-channel audio source; the aim was to mimic a sur­round sound setup for headphones.

Unfor­tu­nately, I can­not find audio exam­ples for this project; I don’t think I will have time to fix some com­pat­i­bil­ity issues in the source in the near future…
