[Freeswitch-users] SILK speech codec, Celt, FreeSWITCH

[Jason White]

I just read a blog post about this.

http://tools.ietf.org/html/draft-vos-silk-00

My main questions about it would be

1. whether it will be licenced in such a way as to permit free
software/open-source implementation in FreeSWITCH. I suppose this partly
depends on IETF's patent policy.

2. How it compares with Celt, which doesn't give rise to any known patent
issues and is available for FreeSWITCH today.

for other FreeSWITCH users who wish to experiment with Celt and listen to
high-quality wide-band calls, it should be noted that Celt is still under
development and backward-incompatible changes have occurred in the past.
Making sure that both endpoints are using the same version of Celt solves
this, otherwise the audible results can be rather unpleasant.
