2016-07-22	getting rid of a PLC overflow (I think)	Jean-Marc Valin

2016-07-22	post-filter saturation	Jean-Marc Valin

2016-07-22	saturate MDCT output	Jean-Marc Valin

2016-07-22	SILK overflow fixes	Jean-Marc Valin

2016-07-21	Avoids undefined behaviour from left-shifting negative values	Jean-Marc Valin

2016-07-20	Fix use_dtx for DISABLE_FLOAT_API	Felicia Lim
	Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
2016-07-20	Fix include warning	Tristan Matthews

2016-07-20	Fix include warning	Tristan Matthews

2016-07-19	Adds some smoothing to the energy quantizationexp_lbr_tune	Jean-Marc Valin
	When the energy is stable, we slightly bias energy quantization towards the previous error to make the gain more stable (a constant offset is better than fluctuations). We reduce the bitrate by about 0.2% to 1% at low bitrate for the same quality.
2016-07-19	Tune SILK rate for hybrid with FEC enabled	Jean-Marc Valin

2016-07-19	Moving FEC decision to the Opus encoder level (from SILK level)	Jean-Marc Valin

2016-07-19	Taking loss rate into account in compute_equiv_rate()	Jean-Marc Valin

2016-07-19	Retuning the tf_analysis() lambda	Jean-Marc Valin
	Increasing the value at low rate seems to help a bit.
2016-07-19	Fixes equiv_rate for CBR	Jean-Marc Valin

2016-07-19	Minor TF cleanup (tf_sum was useless), plus comments	Jean-Marc Valin

2016-07-19	Use SPREAD_AGGRESSIVE on non-transient hybrid frames	Jean-Marc Valin

2016-07-19	Don't use too much temporal resolution on hybrid frames at low rate	Jean-Marc Valin
	Otherwise, we risk having "temporal holes" in the HF that anti-collapse can't always fill in.
2016-07-19	Disable patch_transient_decision() on hybrid since it's causing artifacts	Jean-Marc Valin
	It would trigger on the second frame of "S"s, causing holes in the spectrum
2016-07-19	CBR: set gains to their previons values where we're busting the budget	Jean-Marc Valin

2016-07-19	Set pulses to zero if we can't meet rate target	Jean-Marc Valin

2016-07-19	Now that we're preventing huge gains, we no longer need to pretend there's	Jean-Marc Valin
	no dither
2016-07-19	CBR: lock the gain on a subframe when the number of pulses stops going down	Jean-Marc Valin

2016-07-19	merge back in the LTP gain safety limiter	Koen Vos

2016-07-19	CBR: Using the same gain increase for fixed-point as for float	Jean-Marc Valin

2016-07-19	Oops, edited the wrong comment in the previous commit	Jean-Marc Valin

2016-07-19	Re-tuning compute_equiv_rate()	Jean-Marc Valin

2016-07-19	Getting rid of the SILK penalty for hybrid CBR.	Jean-Marc Valin
	That was likely a mistake from a misunderstanding on the SILK bit allocation
2016-07-19	Improving CBR for hybrid mode	Jean-Marc Valin
	Hybrid CBR now simply forces the SILK CBR rate to the "target" value. Also, we're getting rid of the -2 kb/s offset for CBR, which appeared to be harmful. In the case of hybrid constrained VBR, the cap is computed in the same way as the target.
2016-07-19	Making the encoder more aggressive at using wider bandwidths	Jean-Marc Valin
