Age	Commit message (Collapse)	Author
2012-05-03	Reverts the transient_analysis() changes from 4e8b9905exp_wip4	Jean-Marc Valin
	This was found to cause a quality regression (e.g. in the velvet sample)
2012-03-06	Fixes issues when downmixing to mono or when encoding below fullband	Jean-Marc Valin

2012-03-06	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.
2012-03-06	Converting most of the new code to fixed-point (not complete yet)	Jean-Marc Valin

2012-03-06	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

2012-03-06	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

2012-03-06	Unconstrained VBR no longer attempt to hit an average rate	Jean-Marc Valin

2012-03-06	Fix documenation typos.	Ralph Giles
	Doxygen is smart enough to insert a period if the paragraph before the @see directive, which starts a new section, doesn't have one. Unfortunately it's not smart enough to convert a comma to a period. So while the "description, @see foo" idiom used for the CTL documentation scans well in the header file, the Doxygen output end up with "description,.\n". Minimal change to remove the offending commas.
2012-03-06	Fix typos in the API documentation.	Ralph Giles
	opus_decode() takes a sixth 'enable_fec' option. Naive invocations shoudl set this to zero.
2012-03-06	Restore the windows-side #ifdef check in silk/MacroDebug.h.	Ralph Giles
	We still override the '#if 0' with FIXED_DEBUG, but this leaves whatever Koen intended here more intact. Suggestion from Greg Maxwell.
2012-03-06	Check for underflow in the debug USUB32.	Ralph Giles

2012-03-06	Enable the silk debug macros with FIXED_DEBUG.	Ralph Giles
	This isn't entirely accurate, since it's also used on integer math. However, the idea is similar: to add bounds checking. This code asserts rather than warning, so one must pass --enable-assertions to configure as well to get any output, and in that case the first instance is fatal. Quick testing shows both test_opus_decode and test_opus_encode trigger the assertions, but running the draft-10 test vectors does not.
2012-03-06	Fix a signed-compare warning.	Ralph Giles
	The silk math debug macros include a bounds check on silk_abs. Because INT_MIN = (-INT_MAX - 1), abs(INT_MIN) can't be represented as an int. The macro was checking for this value as 0x8000... without a cast to signed, warning on gcc. silk/typedef.h already defines minimum values for the int types, so we correct the warning by using those.
2012-03-06	Print the actual arguments to the debug UADD/SUB32 routines.	Ralph Giles
	The versions of UADD32 and USUB32 in fixed_debug.h take unsigned long long (ideally 64 bit) inputs, and range check the arguments. However, the printed warnings cast them to (unsigned), which is confusing. Instead, print the full value passed in. NB this will make negative values print has huge, rather than negative, values.
2012-03-06	Uncomment the reporting for UADD32 and USUB32 in fixed_debug.h.	Ralph Giles

2012-03-06	Used unsigned intermediates with unsigned arguments in fixed_debug.h.	Ralph Giles
	Corrects a signed-compare warning.
2012-03-06	Use automake's support for parallel test execution.	Ralph Giles
	On my system this speeds up 'make -j8 check' by about 50%. The drawback is that we don't get to see Greg's nice output from the test programmes. It's hidden in a log file, even on failure or 'make V=1'. Probably this is better for most people; developers can run the tests manually.
2012-03-06	Fix --enable-fixed-point-debug.	Ralph Giles
	Use the celt_mips defined in fixed_debug.h from the unit tests by defining CELT_C earlier. We must export celt_mips so it can be used by clients calling the library, like opus_custom_demo.
2012-03-06	Guard against pathologically small buffer	Vincent Penquerc'h

2012-03-06	Make input mapping parameter const in multistream API	Vincent Penquerc'h

2012-03-06	Adds missing RESTORE_STACK statements on error paths	Jean-Marc Valin
	Thanks to Vincent Penquerc'h
2012-03-06	More consistent types for 16-bit architectures	Jean-Marc Valin

2012-03-06	Removes a number of macro definitions which are used nowhere in the codebase.	Gregory Maxwell

2012-03-06	Various multistream fixes.	Gregory Maxwell
	Fixes the encoder bitrate CTLs to correctly apply to all streams, prevents the MS encoder from starving the latter streams by not reserving a reasonable minimum amount of space for them.
2012-03-06	40/60ms MDCT/Hybrid were not able to reach maximum bitrate. Now they can.	Gregory Maxwell
	Also change the packet length in the API from int to opus_int32 because repacketized frames are able to go beyond 32767 bytes in size.
2012-03-06	Add config.h (and copyright notice) to repacketizer_demo.c.	Gregory Maxwell
	This fixes some problems with cross-compiles.
2012-03-06	Eliminates an unused parameter warning in anti_collapse()	Jean-Marc Valin

2012-02-18	Last updates for draft -11v0.9.9	Jean-Marc Valin
	- Draft updates - Updated code to produce and check test vectors - Making sure that the test vectors pass at all rates as well as for mono and stereo
2012-02-09	Modifies the comparison tool to make it much more permissive.	Jean-Marc Valin

2012-01-31	Fixes MSVC warnings	Koen Vos

2012-01-31	Tweaks the CELT fractional resampling delay to get perfect alignment	Jean-Marc Valin
	Also using the same int->float conversion functions for SILK as for CELT and changed encoder implementation default to constrained VBR just to be safe when VBR gets more aggressive.
