2012-07-14	OPUS_{GET,SET}_LSB_DEPTH for multichannel.exp_analysis6	Gregory Maxwell

2012-07-12	Fixes make dist	Jean-Marc Valin

2012-07-11	Implements OPUS_{GET,SET}_LSB_DEPTH	Jean-Marc Valin
	This is used to avoid dynalloc doing silly things on periodic LSB patterns and to reduce the bitrate on near-silence.
2012-07-05	Builds the analysis files more cleanly than #including C files	Jean-Marc Valin

2012-07-05	Gets rid of // comments	Jean-Marc Valin

2012-07-05	fixed-point (re-)conversion of the VBR code	Jean-Marc Valin

2012-07-05	Fixes a VBR bug with 2.5 ms frames	Jean-Marc Valin
	tf_estimate was being initialized to zero and then never set because transient_analysis() wasn't being called. This could also have affected other frame sizes at lower complexity.
2012-07-04	Speeds up analysis by getting rid of calls to atan2() and cos()	Jean-Marc Valin
	atan2() is replaced by Monty's approximation.
2012-07-04	Rename version flag to exp_wip5 to exp_analysis.	Gregory Maxwell

2012-07-03	Add exp_wip5 tag to version string.exp_wip6	Gregory Maxwell

2012-07-03	Reverts the transient_analysis() changes from 4e8b9905	Jean-Marc Valin
	This was found to cause a quality regression (e.g. in the velvet sample)
2012-07-03	Fixes issues when downmixing to mono or when encoding below fullband	Jean-Marc Valin

2012-07-03	Tonality and pitch tuning	Jean-Marc Valin
	Tuned the tonality estimator to trigger on signals where only part of the spectrum is tonal. Also tuned the pitch detector not to be confused by short-term correlation.
2012-07-03	Converting most of the new code to fixed-point (not complete yet)	Jean-Marc Valin

2012-07-03	Fixes some issues discovered with a log sweep	Jean-Marc Valin
	- New DC rejection filter that avoids numerical issues - Higher cap on HF dynalloc - Proper filter memory for transient detector - Prevents transient detector from detecting low-freq tones as transients
2012-07-03	Tuning the dynalloc adjustments and checking for LF transients	Jean-Marc Valin

2012-07-03	Adds a 3 Hz high-pass filter and boost allocation on leakage	Jean-Marc Valin
	Fixes two leakage problems on the wood blocks sample - Removes DC which causes leakage with no masking - Detect leakage by comparing short-MDCT energy to long-MDCT energy and boost allocation for bands with leakage
2012-07-03	Dynalloc based on a bands that stand out of the "noise floor"	Jean-Marc Valin

2012-07-03	Transient/VBR tuning, give more bits to frames where pitch changes	Jean-Marc Valin

2012-07-03	New transient code, weighted tonality	Jean-Marc Valin

2012-07-03	VBR tuning	Jean-Marc Valin

2012-07-03	Adds automatic bandwidth detection	Jean-Marc Valin
	Haven't tested it much and not sure not to use it without risk for high-quality streams that may change bandwidth
2012-07-03	Better training set	Jean-Marc Valin

2012-07-03	Adds low-energy feature, training with noise	Jean-Marc Valin

2012-07-03	Better training	Jean-Marc Valin

2012-07-03	Adds MFCC standard deviation features	Jean-Marc Valin

2012-07-03	Down to 17 features with same error rate	Jean-Marc Valin

2012-07-03	Adds cepstral mean subtraction (CMS) to analysis	Jean-Marc Valin

2012-07-03	Continuous trim calculations, tapset/spread now use new analysis	Jean-Marc Valin

2012-07-03	Speech/music discrimination (not used for anything yet)	Jean-Marc Valin
	Also, reducing the VBR rate on panned mono
2012-07-03	Cleanup, slightly changed analysis band layout, MFCC-like features	Jean-Marc Valin

2012-07-03	Cleans up the most ugly parts of the analysis code	Jean-Marc Valin
	Should be mostly usable now.
2012-07-03	Adds an analysis function to control VBR	Jean-Marc Valin
	Conflicts: src/opus_encoder.c
2012-07-03	Implements a better transient metric for VBR	Jean-Marc Valin

2012-07-03	Using a "pure L1" metric for tf analysis	Jean-Marc Valin

2012-07-03	Unconstrained VBR no longer attempt to hit an average rate	Jean-Marc Valin

2012-06-29	Add configure option to disable stack protector.	Gregory Maxwell

2012-06-19	Dos2unix, trailing whitespace on draft-spittka-payload-rtp-opus.xml.	Gregory Maxwell

2012-06-14	Adds a copy of the RTP payload XML	Jean-Marc Valin

2012-06-12	Add -fixed to the version string & clarify that fixed disables float.	Gregory Maxwell

2012-06-11	Include the doc dir in DIST_SUBDIRS instead of EXTRA_DIST	Ron
	And explicitly specify what we want included in EXTRA_DIST of doc/Makefile.am, otherwise make dist picks up whatever random junk you might have laying around in that dir at the time you run it. Tweak the top level delegation targets, because this means distclean will be run in the doc dir by default now without our help.
2012-06-11	opus_compare.m was outdated	Jean-Marc Valin

2012-06-11	Don't bark scary warnings at compile time about no doxygen	Ron
	We already report whether or not the docs will be built in the summary box at the end of the configure run.
2012-06-11	Fixup paths in doc/	Gregory Maxwell

2012-06-11	Pretty up the HTML doxygen output.	Gregory Maxwell

2012-06-11	Add brief descriptions to the encode/decode groups to avoid weird autobreif ↵	Gregory Maxwell
	strings.
2012-06-11	Correct documentation in opus_custom.h.	Gregory Maxwell

2012-06-05	Remove unnecessary and not-very-portable opus_demo case insensitivity.	Gregory Maxwell

2012-06-03	Fix doxygen docs wrt OPUS_WARN_UNUSED_RESULT and OPUS_ARG_NONNULL.	Gregory Maxwell
	Also get the subname rigtht.
2012-06-01	Update headers to cause warnings on unused returns and null args.	Gregory Maxwell
	In places where an ignored return or a null-arg is a sure indication of a bug add the GCC warning attributes. The null arg annotation is not enable for Opus itself because it will cause the compiler to optimize out some null checks. I don't trust our callers quite that much.
