I am not sure, but it looks like for given mode AMR and AMR-WB files have
fixed frame size.
"The length of the speech frame is implicitly defined by the mode indicated
in the FT field":

https://tools.ietf.org/html/rfc4867#page-35

Anyway, it is strange that mod_native_file registers AMR and AMR-WB formats
if it could not support them.
