2018-09-25	Retrain RNN classifier weights to include reverberated speech	Jean-Marc Valin

2017-11-10	Retrained speech/music RNN	Jean-Marc Valin
	Larger network, using 8-bit weights
2017-10-06	Add RNN for VAD and speech/music classification	Jean-Marc Valin
	Based on two dense layers with a GRU layer in the middle
2017-02-27	Fix compiler warnings	Mark Harris
	- celt/modes.c:430:14: warning: cast from 'const unsigned char ' to 'opus_int16 ' increases required alignment from 1 to 2 [-Wcast-align] - 'C[0][1]' may be used uninitialized [-Wmaybe-uninitialized] - Unused variable/parameter - Value stored is never read - MSVC warnings about "possible loss of data" due to type conversions - MSVC warning C4146: unary minus operator applied to unsigned type - silk/NLSF_del_dec_quant.c:137:20: warning: array subscript is above array bounds [-Warray-bounds] (gcc -O3 false positive) - src/mlp_train.h:39:20: warning: function declaration isn't a prototype [-Wstrict-prototypes] - Remove SMALL_FOOTPRINT code from SSE 4.1 FIR implementation, matching the C implementation. The clang -Wcast-align warnings with SSE intrinsics are a known clang issue: https://llvm.org/bugs/show_bug.cgi?id=20670
2016-12-20	Makes analysis run at 24 kHz, with 20-ms frames	Jean-Marc Valin
	The change also makes the analysis run for sampling rates of 16 kHz and 24 kHz since the features are only computed on the 0-8 kHz band. The longer time window (20 ms instead of 10 ms) makes the tonality estimator more reliable for low-pitch harmonics.
2016-07-17	Quality: Retrained classifier MLP with better data	Jean-Marc Valin
	New MLP doesn't attempt to classify silence as speech/music
2013-12-10	Making NaN detection more robust to -ffast-math.	Jean-Marc Valin

2013-06-27	Fixes MSVC warnings	Jean-Marc Valin

2013-02-23	Adds silence probability to speech/music detector	Jean-Marc Valin
	Avoids biasing the decision when it's all silence/noise.
2012-12-22	Add float literal suffixes to mlp_data.c.	Ralph Giles
	Fixes an MSVC double truncation warning.
2012-10-30	Adds missing license headers on some scripts and test files	Jean-Marc Valin

2012-07-13	Better training set	Jean-Marc Valin

2012-07-13	Adds low-energy feature, training with noise	Jean-Marc Valin

2012-07-13	Better training	Jean-Marc Valin

2012-07-13	Adds MFCC standard deviation features	Jean-Marc Valin

2012-07-13	Down to 17 features with same error rate	Jean-Marc Valin

2012-07-13	Adds cepstral mean subtraction (CMS) to analysis	Jean-Marc Valin

2012-07-13	Speech/music discrimination (not used for anything yet)	Jean-Marc Valin
	Also, reducing the VBR rate on panned mono
