In recent bioacoustics research, scientists conducted a massive global acoustic analysis of over 100,000 sound recordings spanning more than 3,000 bird species.
Despite the incredible acoustic diversity across the global avian population, researchers discovered that all birdsong is composed of combinations of 8 fundamental acoustic motifs:
- 1. Pure Tone / Whistle (Sine, sustained pitch)
- 2. Frequency Slide / Sweep (Glides)
- 3. Trill (Rapid 2-pitch alternation)
- 4. Buzz / Harsh Grain (Raspy AM noise)
- 5. Click / Transient (Impulsive pop)
- 6. Harmonic Stack (Rich overtones)
- 7. FM Chirp (Vibrato FM modulation)
- 8. Staccato Note (Crisp short note)
AvesMotif programmatically synthesizes these 8 motifs in real-time using native browser Web Audio API DSP nodes (formant filters, frequency ramping, FM synthesis, amplitude-modulated noise) arranged via a Markov chain state machine and supported by an ambient drone layer.
