FreeDV for Android ================== December 2012 Joel Stanley <firstname.lastname@example.org> This application is for using FreeDV on Android. From FreeDV.org: > FreeDV is a GUI application for Windows and Linux (MacOS and BSD are in > testing) that allows any SSB radio to be used for low bit rate digital voice. > > Speech is compressed down to 1400 bit/s then modulated onto a 1100 Hz wide QPSK > signal which is sent to the Mic input of a SSB radio. On receive, the signal is > received by the SSB radio, then demodulated and decoded by FreeDV. > > FreeDV was built by an international team of Radio Amateurs working together on > coding, design, user interface and testing. FreeDV is open source software, > released under the GNU Public License version 2.1. The FDMDV modem and Codec 2 > Speech codec used in FreeDV are also open source. Limitations ----------- FreeDV on Android is currently receive only. Hardware Requirements --------------------- The application requires a USB Audio Class Device to be attached to the USB port of a host-mode capable Android device, running Android 3.2 (API 13) or above. Software Requirements --------------------- Native code was tested using version 0.8d of the Android NDK, building for ARMv7 processors with NEON. The application can be built against Android 4.2, targeting API 17 with minimum of 14 (Android 4.0), under Eclipse.
