org.quietmodem.Quiet allows you to pass data through the speakers on your Android device. This library can operate either as a raw frame layer or as a UDP/TCP stack.
This package contains prebuilt library files for libquiet and quiet-lwip as well as their dependencies. On top of that, it adds Java bindings which closely mimic the familiar interfaces from the java.net.* package.
This package is provided under the 3-clause BSD license. The licenses of its dependencies are also included and are licensed under a mix of BSD and MIT.
Quiet comes with support for armeabi-v7a, arm64-v8a, x86, and x86_64. It requires Android API 14 for 32-bit mode and API 21 for 64-bit mode. It requires only the
For testing purposes, Genymotion is highly recommended over the default emulator. Genymotion provides access to the microphone while the default Android Studio one does not and will throw an exception when Quiet attempts to use the microphone.
If you are old enough, you may remember using dial-up modems to connect to the internet. In a sense, this package brings that back. While it’s true that this is somewhat of a retro approach, consider the advantages of using sound.
- Highly cross-platform. Any device with speakers and a microphone and sufficient computational power can use this medium to communicate.
- No pairing. Unlike Bluetooth, sound can be used instantly without the need to pair devices. This reduces the friction and improves the user experience.
- Embeddable content. Similar to a QR code, short packets of data can be encoded into streaming or recorded audio and can then be later decoded by this package.
