OpenCORE Adaptive Multi-Rate Narrowband encoder.

Requires the presence of the libopencore-amrnb headers and library during

configuration. You need to explicitly configure the build with
|

@code{--enable-libopencore-amrnb --enable-version3}.
|
||||
|

This is a mono-only encoder. Officially it only supports 8000Hz sample rate,
|

but you can override it by setting @option{strict} to @samp{unofficial} or

lower.
