Game developers are now turning to convolution reverberation effects in order to offer an immersive and realistic audio experience. This requires impulse response data that is either recorded or generated artificially, and that ideally matches the in-game environment. To help this process the Open Acoustic Impulse Response (OpenAIR) Library has recently been made available. It consists of an online resource designed to facilitate the sharing of acoustic impulse responses and related information. Open-source software tools are also provided, including an external library for the Pure Data (PD) programming environment that implements real-time convolution. Details of this tool are described in this paper, along with an example that uses computer generated impulse response data to auralize a space in real-time.
