CW Edge Length: At this point, this is only for the ANAN-G2. The ability to load CW edges is not available in legacy ANAN products. The minimum Edge Length is 15ms which, based upon testing, is required to meet the new ARRL Guidelines. However, due to the edge shape, a 15ms total edge yields about 5ms in the range of 10% - 90% amplitude, i.e., the 15ms number is a bit misleading.
-New NR : There are actually a few new things in NR: (1) the "Trained" gain method as described below, (2) an alternative Noise Power Estimation method I called "NSTAT" which should have a faster response to changing noise levels, and (3) some code added in the AE Filter that removes an annoying rumble that could occasionally occur.
New NR : has a file (zetaHat.bin) that gets copied into the execution directory – it's a data file that contains the essential information extracted from "training" the algorithm. The algorithm is currently "trained" with about 72 hours of noise and speech recordings.
