brief demo of all 3 CW OPs sending CW at the same time to show the full duplex audio quality of a LINPHONE CONFERENCE CALL using the "BV16" audio codec(very low latency, full QSK breakin, & good audio fidelity of the CW AUDIO tones)
each CW OP is using a different OS version of LINPHONE
CWop 1 = Mac
CWop 2 = Linux
CWop 3 = Windows 10

The following list summarizes the attributes of the BroadVoice16 :(BV16 audio codec)
- Low Delay (Latency): algorithmic buffering delay of merely 5 ms (compared with 15 to 40 ms of most competing codecs)
- Low Complexity: much lower MIPS requirements than most competing codecs (typically 1/3 to 1/2 of comparable ITU-T G.72x codecs), also lower memory requirement than most competing codecs
- High Quality: equivalent or better speech quality than most competing codecs in PESQ comparisons and in extensive formal subjective MOS listening tests conducted by AT&T Labs, COMSAT Labs, and Dynastat, Inc
- Moderate Bit-Rate: at 2 bits/sample, coding efficiency is higher than G.711, G.726, and G.722 and comparable to many other codecs
