Built McNeal Protocol: Acoustic encrypted messaging with per-message frequency ratcheting

on

About 6 months back I posted T3E encryption - encrypting files into .wav audio that got some

traction here.

I've since built it into a complete protocol called McNeal with:

X25519 key agreement + ChaCha20-Poly1305 encryption

Double ratchet (forward secrecy)

Real-time internal microphone decode (no file transfer needed)

Per-message frequency randomization

Works over phone calls, air-gap, any audio channel

Key upgrade from T3E:

- T3E: Static encryption: file-based

- McNeal: Ratcheted keys , real-time streaming, acoustic transport

Deploying in a messenger app in January. Looking for people to stress test.

For anyone who analyzed the T3E waveform back then - this uses the same

acoustic encoding but now with proper key agreement and forward secrecy.
