EVS
---
Enhanced Voice Services (EVS) is a patent-encumbered codec for which (at the
time of writing) no implementation exists which can be freely used and
distributed. As such, support for EVS is only available if an implementation is
supplied separately. Currently the only implementation supported is the
ETSI/3GPP reference implementation (either floating-point or fixed-point). Any
licensing issues that might result from such usage are the responsibility of
the user of this software.
The EVS codec implementation can be provided as a shared object library (*.so*)
which is loaded in during runtime (at startup). The supported implementations
can be seen as subdirectories within the `evs/` directory. Currently supported
are version 17.0.0 of the ETSI/3GPP reference implementation, *126.442* for the
fixed-point implementation and *126.443* for the floating-point implementation.
(The floating-point implementation seems to be significantly faster, but is not
bit-precise.)
To supply the codec implementation as a shared object during runtime, extract
the reference implementation's *.zip* file and apply the provided `patch`
([from here](https://github.com/sipwise/rtpengine/tree/master/evs)) that is
appropriate for the chosen implementation. Run the build using `make`
(suggested build flags are `RELEASE=1 make`) and it should produce a file
`lib3gpp-evs.so`. Point *rtpengine* to this file using the `evs-lib-path=`
option to enable support for EVS.
