about

Audible range of the waves emitted by function generators type KZ 1406 0.0005 Hz-100 kHz, produced in the 80's by the Polish Institute and Scientific Equipment Manufacturing -Zopan was used to create sound on these CD’s. The starting material are pure components: sine , rectangle, sawtooth wave, white noise only occasionally used depending on amplitude modulation AM and FM frequencies forming a small variation between the clear signals arranged in small distances, eg:
SIN 152.7 Hz, SQ 120.6 Hz, SAW 70.3 Hz, SQ 62.5 Hz
Module AM and FM:
KZ 1406/1 FM 152.7 Hz sine-> 70.3 Hz sawtooth
KZ 1406/2 AM 120.6 Hz square -> 62.5 Hz square
Study of dependence between pure tones emphasizes the basic assumptions about the sound generated and refers to the first experiments on the conversion of electric waves to audible sounds. All pieces were recorded live during the session in which five device type Zopan KZ were used in real-time.
