Notes

  • Program notes: 

    «FLUTR. You wave your hands like fluttering wings,...but you cannot fly!»
    “The piece is inspired by all aspects of fluttering: the world ́s fluttering drive into disorder, abnormal heartbeats, rapid permutations of something that might be a melody trying to reach the sky but is trapped like a Flutter Echo between two parallel, reflecting surfaces common in many rooms. The major sound effect is the extensive use of an algorithm simulating not only the rhythmic and directional aspects of flutter echoes, but more important: the rapid, gradual change of timbre, (which in real rooms is due to diffraction and the transformation of spherical waves into plane waves), giving the mid-/high frequency “tail” typical of flutter echoes. This material is then manipulated further, with extreme settings that of course do not appear in real rooms. In order to perceive the “reflections between the “walls”, the piece is a mixture of two layers: a quadrophonic layer and a more overall layer incorporating all loudspeakers.

  • Technical specs: 

    The composition will be presented as 8+1 ch. wav-file, 44.1 kHz, 16 bits.
    All speakers should be of the same type/size. The piece will be given as 8+1 ch. wav-file, thus including a dedicated sub-bass-track (track 9). If you set up does not provide a 9 ch. playback, the sub-channel must, of course, be skipped, but the inclusion of this sub is highly recommended. The sub-bass speaker should be positioned between speaker 1 and 2 in the first picture above.
