Reverberation is an audible effect that is heard every day as a result of sound interacting with the environment around the listener. It is an effect that is commonly added artificially to electronically recorded and produced music, as well as in other media such as cinema, virtual reality applications and computer games. Auralization is an increasingly popular technique for accurately simulating reverberation and this website supports this practice through an expanding library of downloadable acoustic impulse responses (IRs) from interesting buildings, spaces and other sources. Some examples of the data found in the library can be seen in the slideshow to the right. Click on IR Data to browse the entire database.

You can also find a library of sounds recorded in an anechoic environment on this website. Click on Anechoic Data to browse this content and download the data.
