<div dir="ltr">I believe HPEC actually is the same algorithm (G.168) that the HW echo cancel modules use.. the difference being that HPEC uses up CPU cycles and its performance will be impacted on a system with higher CPU load, whereas the HW modules have a dedicated DSP for it.<br>

</div>I don't think the hardware echo cancellers use the HPEC algorithm. As<br>
Eric and Matt have mentioned, dmseg will tell you if a hardware echo<br>
cancel module is being loaded.<br>
