libambix-dev binary package in Ubuntu Oracular s390x

 libambix is a library of C routines for reading and writing files following the
 "ambix" (AMBIsonics eXchange) conventions.
 .
 Ambisonics is a periphonic (3D) surround sound technique, with a scalable
 spatial resolution (put simply: "the more audio channels you use, the better").
 The ambix convention defines an extensible format for exchanging soundfiles
 containing Higher Order Ambisonics data.
 .
 This package provides the files necessary to compile an application
 using libambix.
