Hi Product Hunt! 👋 I’m Dippan, the maker of SSTV Studio. I’ve always been fascinated by Ham Radio and the idea that you can send images over analog audio waves (like the fax machines of the airwaves!). Usually, decoding these signals requires installing complex desktop software. I wanted to challenge that by building a fully capable DSP (Digital Signal Processing) modem entirely in Vanilla JavaScript. The Tech Stack: ⚡ Web Audio API (for sample-accurate synthesis) ⚡ Canvas API (for the 60fps spectrum visualizer) ⚡ Zero server-side code (it works offline!) Fun Challenge: You can actually test it right now! Open the "Encoder" on your phone, generate a signal, and hold it up to your laptop's microphone running the "Decoder". It feels like magic. ✨ I’d love to hear your feedback on the signal clarity or the UI design! Happy decoding! 📡
