Impulse Response No. 1 by Knut Aufermann

What a joy to work with so many great recordings that came from the call to sustain the music! In constructing this piece I decided to follow my initial impulse after listening to all the minute parts. I picked a sound that seemed like a nice beginning and then added others that seemed to fit. Due to the standard length of most recordings the outcome consisted of five sections that are more or less equally long. Overall I used almost all tracks that were sent in. All I did was to place them in the stereo spectrum, set the levels, and in some cases cut them short. There is only one added effect in the piece, a long reverb at about 2:45. This reverb is created with the help of a so-called impulse response recording I made 12 years ago − a small sound file that captured the echo response of the wine mountain behind the house I live in which you can see in the photo. This reverb is what it would have sounded like if the LIO had played facing this hill.
