David 3ac5cee235 ctests pasing again 2019-09-29 08:50:57 +09:30
David fb2d791b2e use 190924a tar ball as default 2019-09-29 07:52:02 +09:30
David 69bdcfbd06 cleaned up dump data a little 2019-09-29 07:00:00 +09:30
David 02ecf2ac30 190924a, using original LPCNet voicing est (pitch gain). I have accidentally written over the 190922a network with c2voicing, so will run again 2019-09-24 19:00:44 +09:30
David 49c95df13d cq_16kHz fine, peter a bit spikey, slightly better than 190920c, but not as gd at 190920a. However, quite remarkably - all.wav sounds fine, even outliers like canadian. This is puzzling, as this training material doesn't include resampling, or wianews sample 2019-09-23 06:51:26 +09:30
David 24bc72efef 190920c in between 190215 and 190920a, not quite good enough 2019-09-22 14:45:44 +09:30
David 18c4f2ba33 just peter and david, but cepstrals rather than mags, sounds as good as previous with mags 2019-09-20 11:27:54 +09:30
David a2df6288a9 training script with just Peter and David that produces improvements over the 190215 network 2019-09-20 07:34:34 +09:30
David f86b8da270 about to reconfigure for just vk5apr and david 2019-09-19 05:36:29 +09:30
