This is an AMBE vocoder plugin based on mbelib and the OP25 AMBE encoder. The makefiles create a shared object for various platforms that can be loaded via dlopen() (LoadLibrary on Windows).

Compiling

All platforms require imbe_vocoder library be built and available for the platform being built. The default Makefile is for a Linux PC. MacOS can also use this file, just comment out the linux line and use the darwin line. The Makefile.win for windows requires a static mingw32 compiler.

Loading a plugin on Linux/MacOS/Windows

You can place the correct plugin in your ~/Downloads folder and DroidStar will copy it to the config directory where settings and host files are located. Once it has been copied, you can remove it from the Downloads folder. If you leave it in the Downloads folder, it will be re-copied every time you start DroidStar. You can also use the URL download option, but if a vocoder exists in the Download location, it will always overwrite the working copy
