Merge pull request #10 from drowe67/dr-vec-compare 
automated tests for LPCNet states & new network for peter and david
 2019-10-09 18:50:33 +10:30
David a00820d7f9 fixed bug that was causing unstable audio - pitch output from quantiser sometimes dropping beneath 40 which embed matrix wasn't trained for 2019-10-09 18:22:32 +10:30
David f8b793f4b0 add peter and david samples 2019-10-07 08:19:53 +10:30
David 64c066c409 Merge branch 'dr-vec-compare' of github.com:drowe67/LPCNet into dr-vec-compare 2019-10-06 07:04:53 +10:30
David 8c3b64b34e fixed bug in codec2_pitch.c that was casuing problems with interpolation/decimation on 190924a. We were training using a discrete PDF of pitch values, so pitch embedding failed when we interpolated pitch during quantisation 2019-10-06 06:59:46 +10:30
David 82ef384370 ramp generator to test decimation/interpolation in quant_feat - no problems found 2019-10-04 14:39:23 +09:30

David 16d2733c19 ctests working on Ubuntu 16 aand 18, but not 17. It's not ideal, but a way fwd for now 2019-10-01 06:19:08 +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
