Inspired by my earlier interaction with Mike Phillips I thought it would be interesting to get some hands on experience with Opus. It would be worthwhile staging a little test to better understand the audio path presented in one or more Opus implementations.
A quick Google search revealed that PhonerLite, the freeware Windows soft phone from Germany, includes Opus from the v1.92 release onward. According to the release notes support for Opus replaced support for CELT. The current release is v2.08 from April 16, 2013.
I had first encountered PhonerLite some time ago, when I was seeking a G.722 capable soft phone. It’s very functional but a bit quirky.
