Two Tone Techno (2021)
While experimenting with very basic principles of electronic sound - sine waves, white noise, sampling rates, one result became my submission for Community Scratch Games 2021 experimental category.
The piece is firstly built from two alternating sine tones, one a very low frequency, the other very high (just within my own hearing range). This alternation is controlled using [Gen~] within Max for sample accuracy, this allows to cut each wave at a different position in its phase giving rise to a huge variety of rhythmic possibilities.
White noise is then filtered and gated and finally the original two sine waves are degraded using a rolling downsample, this lowers the nyquist frequency and folds over the waves creating many more frequencies. See video at the bottom of the page for a visualisation of this process.
The final video is composed using footage from Edward Moybridge's early studies of human motion. The luminosity values are mapped to a z-plane and controlled by the audio amplitude to give the moving images a third dimensionality.
The video below shows a sonogram of the sine waves being downsampled over time and shows the complexity of the signal. 15X Speed.
