The Concept

“The doodler” is a generative art experiment, an exploration of the idea of digital automatism. It is a machine that listens to the chaos of sound and produces an irrational looking doodle. It rejects the idea that complex analysis should serve a logical purpose. Instead, it uses sophisticated audio-feature extraction to make absurd, aesthetic decisions. It’s dada in spirit, embracing chance.

What is Dada?

Dada was an art movement of the European avant-garde in the early 20th century. Born from the chaos and trauma of World War I, it was a profound “anti-art” protest. Dadaists rejected logic, reason, and aestheticism, instead embracing nonsense, irrationality, chance, and absurdity as their primary tools. It was a movement that sought to tear down old traditions and question the very definition of art itself.

Automatism and the Digital Hand

The Surrealists inherited Dada’s chaos but turned it inward — toward the subconscious and the instinctive hand. Automatism asked the artist to draw without thought, to let gesture arrive before judgment. It was a way to free creation from conscious control, allowing the unconscious to express itself through movement.” This artwork experiment borrows that idea but translates it into code. The computer becomes the hand; the song becomes the subconscious. Each image emerges from thousands of small decisions made in real time


The Strategy

  • Automatism: The “artist” here is a machine. It removes the conscious, logical hand of the human creator. The doodle is the immediate, unconscious product of the audio input.
  • Chance Operations: The audio file is a “found object”. Like pulling words from a hat for a poem, this machine pulls features from the sound. The final artwork is a direct result of this chance operation. You set the machine’s rules, but the audio provides the chaos.
  • Irrationality & Absurdity: A stable vocal pitch triggers a “calligraphy” brush. A sudden drum hit cause a “splatter”. There is no logical reason.
  • Anti-Art: The canvas is not a grand, archival sheet. It’s a procedurally generated piece of ruled notebook paper. This rejects the pretension of “high art” in favor of the doodle, the most immediate, and universal form of drawing.

The Machine’s “Guts”

The automaton is built with several “organs”:


  • The Ear (Meyda.js & p5.sound): Listens to the sound’s soul, analyzing its timbre (MFCCs), pitch (F0, chroma), energy (RMS), and rhythm (onsets) among other things.
  • The “Vocal” Brain (Vocal Detector): An internal logic that tries to distinguish a human voice from the instrumental chaos by looking for stable pitch, high chroma concentration, and low spectral flatness.
  • The Motor (Movement Modes): Decides how to move, whether in a chaotic Lévy Flight, an anxious Hesitation, a predictable Grid, or a lyrical Lissajous curve.
  • The Hand (Brush Modes): Chooses its tool. It may use a bristle brush for backing tracks, a sharp calligraphy nib for vocals, or simply splatter the paint in response to a beat.




Few Final Thoughts

Ultimately, “The Doodler” is a question posed in code. It wonders if the “unconscious” hand of the automatist can be digitally simulated, not through artificial intelligence, but through an absence of traditional, goal-oriented logic.


Each piece that emerges is not a final answer, but the artifact of a unique performance, a testament to the idea that, art(compelling or not) can be born from chaos, chance, and the beautiful, absurd rejection of reason.
