Profiler is a tool that lets you optimize the way SoundScape3D renders sound binaurally over headphones. Binaural rendering involves the use of Head Related Transfer Functions (HRTF) to give listeners the impression of a sound coming from a certain direction. Because they are based on the shape of a person’s head, pinna, and upper-body, HRTFs are unique to each individual. This creates a problem because measuring each listener’s HRTF is an involved process and is not practical in most cases.

As a remedy to this, we’ve pioneered the use of a best-fit selection process that finds the best matching HRTF for each listener from a database of over 90 HRTFs. Profiler does this using a scientifically validated technique that guids the user through a series of listening tests resulting in the selection of their optimal HRTF. This process results in the creation of a listener profile that can be selected for use in VibeStation.
