FFT-based demodulation recovers intent values by analyzing peak frequencies in a phase-modulated audio waveform. It extracts the encoded phase shifts from the 440 Hz carrier signal, allowing robust intent recovery even when configurable noise is applied to the transmission channel.

To encode an audio intent, provide a decimal value between 0 and 1 to generate a 0.5-second phase-modulated waveform. The encoding applies the intent value as phase shifts onto a 440 Hz carrier signal, creating an audio waveform ready for transmission.

Yes, phase-modulated audio signals support inter-module governance checks by providing an auditable, signal-based intent transfer mechanism. The encoding and decoding process ensures that intent values are securely transmitted and recovered within controlled governance environments.

Audio intent demodulation is designed for noisy signal environments using configurable noise settings during the encoding process. The FFT-based demodulation technique robustly analyzes the 440 Hz carrier to accurately recover the original intent value from the degraded audio.

Using a 440 Hz carrier for phase modulation limits transmissions to a narrow frequency band suitable for controlled tests rather than broadband audio. The 0.5-second waveform duration also constrains the data throughput rate for signal-based intent transfer.
