Profile

A fun weekend project: https://www.modembin.comIt's a pastebin, except text/files are encoded into .wav files using real FSK modem audio. Image sharing is supported via Slow-Scan Television (SSTV), a method of transmitting images as FM audio originally used by ham radio operators.Everything runs in the browser with zero audio libraries and the encoding is vanilla TypeScript sine wave math: phase-continuous FSK with proper 8-N-1 framing, fractional bit accumulation for non-integer sample rates, and a quadrature FM discriminator on the decode side (no FFT windowing or Goertzel), The only dependency is lz-string for URL sharing compression.It supports Bell 103 (300 baud), Bell 202 (1200 baud),

The company sits in the show hn launch segment, where it competes on its core product or service.

Directory data places it at the Show HN launch stage.
