 FFmpeg currently does not have a decoder for AMR-WB+ codec.

 A free encoder + decoder for AMR-WB+ can be downloaded from
 https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1451.
 The ZIP file has both binaries (encoder.exe, decoder.exe) and source code.

 Here are some usage instructions,
