libvo-amrwbenc
VisualOn Adaptive Multi-Rate Wideband encoder.
Requires the presence of the libvo-amrwbenc headers and library during configuration. You need to explicitly configure the build with --enable-libvo-amrwbenc --enable-version3

This is a mono-only encoder. Officially it only supports 16000Hz sample rate, but you can override it by setting 'strict' to 'unofficial' or lower.
