Polyglot Radio: Acoustic SDR

Polyglot Radio harnesses your device’s built-in speaker and microphone to send and receive digital and analog waveforms through the air. Powered by a high-performance native C++20 DSP core and a modern Flutter interface, Polyglot Radio continuously scans, arbitrates, decodes, and transmits 11 acoustic and near-ultrasound communication protocols—no extra radio hardware required! KEY FEATURES Autonomous Parallel Sentry: No manual mode switching required. Polyglot Radio simultaneously monitors matched-filter and energy-bank correlations across all supported waveforms, auto-detecting incoming preambles, VIS codes, and sync words to promote the correct decoder instantly. Real-Time Spectrogram Waterfall: Visualize incoming audio signals with a fluid, 512-bin rolling FFT waterfall running at 30 FPS. Zero-Copy Shared Canvas: Watch analog image sweeps decode line-by-line in real time on a…
