Show HN: Waver – Messaging Through Sound
- ggerganov 6y agoThis is a messaging app that sends and receives text messages through sound. I tried to make the transmission to be reliable for reasonable distances - say up to 5 meters across the room. It uses FSK modulation and supports both audible and ultrasound transmission. The app is free, open-source and is available on multiple platforms: iOS, Android, Web. I'm really looking forward to some feedback about the performance and ideas for future applications. Thanks!
