Sonic Genome — Real-Time DNA Audio Synthesizer & Acoustic Playground

1. Harmonic Scale Degree Mapping

Individual nucleotides map to scale intervals: Adenine (A) to the root tonic, Thymine (T) to the mediant 3rd, Cytosine (C) to the dominant 5th, and Guanine (G) to the 7th or upper octave. Codon triads ( $3\text{ bp}$ ) trigger full harmonic chord voicings.

2. Dynamic GC% Low-Pass Filter Sweeps

The sliding window GC-content ratio ( $GC\%$ ) dynamically modulates a $24\text{ dB/octave}$ low-pass filter: high GC opens cutoff frequencies up to $6,000\text{ Hz}$ , whereas AT-rich regions create dark subterranean resonance.

3. Regulatory Motif Drum Synthesis

Genomic regulatory motifs trigger synthesized analog percussion:

TATA Box Promoters ( $\text{TATAWAW}$ ): Sub-bass 808 kick drum
E-Box Motif ( $\text{CACGTG}$ ): Snare drum
CTCF Insulators ( $\text{CCGCGNGGNGGC}$ ): Resonant woodblock
Polyadenylation ( $\text{AATAAA}$ ): Shimmering high arpeggios
