Akos Janca

description | etude for graphical additive sound synthesis
realization | drawn microtonal stereo spectrogram
summary | The piece is based on a 65.4 Hz frequency pure sinewave (the great C note). Its additional harmonics are created artificially, resulting changes in composition of spectrum, rhythm and volume.
premiere | 7 June 2017, Liszt Academy, Budapest, HU

SPEKTRA, excerpt • pulsation and noise that builds up and then fades into one

SPEKTRA, excerpt • offset, tinkling overtone-garlands

SPEKTRA, excerpt • a close up of two small sinusoidal components, approx. 8 cents apart and shifted in time, approx. with 60 ms attack

SPEKTRA, excerpt • contrast of comb-like complementary spectrum components: one continuous, the other intermittent, accelerating-decelerating

SPEKTRA, excerpt • rhythmic contrast: accelerating and decelerating pulsating components close together

SPEKTRA, excerpt • nice tinkling sound: components out of time, then synchronizing, coming together into one sound

SPEKTRA, excerpt • inverse timbre-melody (v-shaped sweep, notch filtering), which eventually blends into the harmonic spectrum

SPEKTRA, excerpt • recurring v-shaped principles: in time, amplitude etc.

SPEKTRA, excerpt • moving the timbre by changing the amplitude of the spectrum components (and also dashing)

SPEKTRA, excerpt • time-synchronizing components approx. a semitone apart (at the line) and then shifting them again
