Description
Working with Fable 5, a MacBook, and a Pixel phone, I built an acoustic transport library that is several orders of magnitude faster than existing SoTA open source options like ggwave, quiet, minimodem, or Chirp.Paper: https://cyrinx.org/cyrinx-acoustic-link.pdfApache 2.0 source: https://github.com/dweekly/cyrinx

Could you build this?
No Achieving high-throughput acoustic data transmission over commodity microphone and speaker hardware is novel physical-layer telecommunications and digital signal processing research.
What it would actually take: The software is written in low-latency C and Swift, implementing advanced digital signal processing techniques including Orthogonal Frequency Division Multiplexing (OFDM), channel estimation, adaptive equalization, Doppler compensation, and forward error correction (LDPC or Reed-Solomon). The primary barrier is overcoming severe non-linear acoustic distortion, multipath reflections, and aggressive hardware filtering present in commodity smartphone and laptop audio chips. This requires doctoral-level expertise in communications theory, acoustic physics, and real-time DSP.
