⚡ Executive Summary

Generative audio models (Suno, Udio, ElevenLabs, Google SynthID) inject proprietary synthetic watermarks, high-frequency ultrasonic carriers (19.5 kHz), phase-locked spread spectrums, and latent provenance tags into generated waveforms. When musicians, producers, or sound designers incorporate AI stems, sound effects, or background textures into human compositions, their entire track becomes forensically tagged for platform surveillance and automated copyright attribution.

NaSuno is a defensive, mathematical signal processing framework designed to decouple human musical creativity from synthetic platform tracking. Built on ISO 226 equal-loudness contours, Bark-scale critical-band psychoacoustics, and zero-phase IIR notch filtering, NaSuno strips forensic tracking markers while maintaining complete spectral transparency, transient punch, and stereo correlation.

1. Ultrasonic Carrier Notch Filtering (19.5 kHz)

• Zero Phase Distortion: Uses bi-directional forward-backward IIR filtering ($Q \ge 30$) to eliminate ultrasonic pilots without introducing phase smearing or ringing in upper harmonics.
• Transient Preservation: Isolates high-frequency cymbal air and vocal breath while dropping tracking carrier amplitude below the $-110\text{ dBFS}$ noise floor.

2. ISO 226 Perceptual Masking Engine

• Bark-Scale Critical Band Analysis: Evaluates instantaneous masking thresholds across all 24 human auditory critical bands.
• Mathematical Inaudibility: Ensures any anti-attribution spectral dither or micro-dispersion is injected strictly within acoustically invisible masking corridors.

3. Latent & Sub-Band Dispersion

• Spread-Spectrum Neutralization: Scrambles pseudo-random watermark chip sequences embedded across mid-range acoustic formants.
• Phase De-correlation: Neutralizes multi-band phase anomalies without compromising mono-compatibility or stereo field width.

4. Container & Provenance Sanitization

• Deep Metadata Scrubber: Strips hidden C2PA provenance manifests, RIFF INFO chunks, ID3 tags, and BWF acoustic metadata.
• Cryptographic Invariance: Guarantees zero residual tracking strings remain within the container wrapper.
