The image is the score. Paint bright marks onto the spectrogram; the cyan playhead reads each column as a bank of pure sine partials. Vertical = log-frequency, horizontal = time.
An image-as-score additive resynthesiser in the black-and-white idiom of Ryoji Ikeda. Row → log frequency (55 Hz – 7.5 kHz), brightness → partial amplitude. Draw a spectrum and hear it.
Sound + the playhead start on this tap. Then draw anywhere, or load a preset below.
