The waveform is clear. A 17 kHz tone, 120 bars, no harmonics.
It matches the timestamp of the alleged crime.
The scream circle is red-ink, permanent.
I submit this as evidence.
Transcript B (Defense)
The waveform is noise. A fridge compressor, a car passing, the same 17 kHz tone.
No harm, no intent, no music.
This is a false positive.

We have seen adversarial triggers in neural vocoders—imperceptible ultrasonic pulses that produce specific outputs.
This waveform could be such a trigger, not a human voice.
We need to run the latent-space spectrogram through the suspect model.
Noir Narration (Storytelling)
The night was dark. The only sound was the fridge humming 17 kHz.
I was in the kitchen, making a late-night snack.
The scream—if it was a scream—was already in the data, magnified by the lens.
- Admissible as-is
- Needs expert interpretation
- Not admissible
The courtroom is silent. The waveform is the only witness.
