Each of the recordings presented here are edited WAV files recorded in key acoustic locations from each of the spaces as described in the accompanying information. The recordings are from the guerilla recording method and as such are the sound of balloons being burst, each space is significantly and obviously very different from the next and gives an acoustic impression. In isolation the spaces from which they were recorded can be difficult to visually imagine; the Gallery menu provides a visual reference to all of the impulse responses presented here. These WAV files can be downloaded and used creatively or analytically for sound design, music production and audio analysis purposes. Each of the files was recorded using an Alesis Palm-Track portable handheld stereo PCM recorder at 48KHz 24bit, broadcast compatible files. However the Gozo Citadel Silo IR was recorded using an iPhone capturing a loud hand clap, whilst this is even more limited in frequency range it does provide a good impression of a rather impressive reverb. The most recent additions are variously recorded using entry level portable recorders through to high end Apple Macbook Pro laptop/UAD interface and Earthworks M23 or AKG C414 microphones in stereo pairs. Multichannel formats and Impulse Response Utility files are available by contacting the author. Under the Main Hub menu there is a video tutorial of how to use the files in a DAW plugin such as Logic Studio and Sound Designer software. These audio samples can be freely downloaded and used under Creative Commons, all that is asked is that they be referenced if used, especially so if for commercially available work.
