What is a transfer function in audio?
With Transfer Function, you can make changes to a sound system without having to run pink noise or swept sine waves through the system. This allows you to monitor system performance, or make adjustments, while the system is in use and the crowd is in the room.
How does HRTF audio work?
Head related transfer functions (HRTF) describe how sound signals bounce, scatter, and diffract when they arrive at the head, and travel towards the ear canals. HRTFs produce distinct sound patterns that ultimately help the brain infer the spatial properties of the sound, such as its direction of arrival, ��.
What is a HRTF file?
Head-related transfer functions (HRTFs) describe the spatial filtering of the incoming sound due to the listener's anatomy. HRTFs are crucially important for the binaural reproduction of virtual acoustics. HRTFs have been measured by a number of laboratories and are typically stored in each lab's native file format.
How is HRTF measured?
The HRTF measurement is typically performed in an anechoic chamber, which is used to simulate the free-field environment. In the early stage of acoustic research, analog methods were applied for measuring acoustic impulse responses, e.g., using the signal generator and level recorder, etc.
