+Requires the presence of the libvo-amrwbenc headers and library during

+configuration. You need to explicitly configure the build with

+@code{--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 @option{strict} to

+@samp{unofficial} or lower.
