2013-11-30mips C equivalent: Using simple rounding rather than the original biasexp_mips_altJean-Marc Valin
The bias was only needed because the original code rounds towards -inf on every multiplication.
2013-11-30Merge branch 'master' into exp_mips_altJean-Marc Valin
2013-11-30Whoa! This fixes a pretty bad fixed-point stereo regressionJean-Marc Valin
2013-11-30Fixes the mips_alt buildJean-Marc Valin
2013-11-30Merge branch 'master' into exp_mips_altJean-Marc Valin

2013-11-29Fixes OPUS_SET_GAIN (was a bug in MULT16_32_P16())Jean-Marc Valin
2013-11-27Minor speedups to celt_pitch_xcorr_edsp().v1.1-rc2Timothy B. Terriberry
This moves some stuff out of the main loop for the unaligned case.
2013-11-27Drop the use of --always to git-describeRon
This is a partial revert of c435f06b308e52d7a5d2aad9eec98a1541832b47, since it didn't actually fix the original problem with shallow clones. It returns just a hash, not something we (currently) can extract as a version string in the form things are expecting.
2013-11-27Remove the celt_pitch_xcorr() test code.Timothy B. Terriberry
Revision control will remember it for us forever.
2013-11-27Actually use my NEON code.Timothy B. Terriberry
I'd commented out mine and stuck azanelli's code in for testing, and then accidentally committed it like that.
2013-11-27Make celt_pitch_xcorr_edsp() work on ARMv5TE.Timothy B. Terriberry
We were assuming that LDR, LDRD, and STRD could be used on unaligned addresses, but this turns out not to be true on really old hardware.
2013-11-27Clean up celt_pitch_xcorr() test code.Timothy B. Terriberry
This will be removed shortly, but at least it should be correct before it goes. Makes the code get used unconditionally (when uncommented), and actually frees the buffer it allocates (now using the libopus allocation functions).
2013-11-26Silences a warning in fixed-pointv1.1-rcJean-Marc Valin
2013-11-26Merges surround and stereo intensity stereo thresholds again.Jean-Marc Valin
The different results for surround were mostly due to a bug in squishyball.
2013-11-25Makes SILK surround masking a bit more aggressive in both directionsJean-Marc Valin
This also splits the rate adjustment between SILK and CELT (previous code only changed SILK)
2013-11-25Intensity stereo update, partially based on Monty's listeningJean-Marc Valin
Intensity stereo is now based on equiv_rate and should no longer oscillate in hybrid mode. Also, there is now a separate set of thresholds for surround tuned by Monty. The non-surround thresholds were also updated at low bitrate to be closer to what Monty found for surround.
2013-11-24Put custom_encoder_init decl behind CUSTOM_MODES. More softclip tests.Gregory Maxwell
This removes an unused definition warning when compiling without custom modes.
2013-11-24Using a more reasonably SILK surround calibration valueJean-Marc Valin
Still needs more tuning
2013-11-24Reducing the thresholds for enabling stereo and higher audio bandwidthsJean-Marc Valin
2013-11-24Surround low-passing thresholds set to much lower bitratesJean-Marc Valin

2013-11-19More make dist fixesRon
Don't include the generated celt/arm/celt_pitch_xcorr_arm-gnu.S in the dist tarball, but do include its celt_pitch_xcorr_arm.s source file.
2013-11-19Fix 'make distclean'.Ralph Giles
Automake's dependency tracking seems to be confused by our asm generation double-indirection. It's sufficient to have just CLEANFILES = $(CELT_AM_SOURCES_ARM_ASM:.s.in=-gnu.S) to fix the error about 'armopts-gnu.S' not being cleaned, but celt_pitch_xcorr_arm-gnu.S is also not cleaned without raising a warning. Therefore we explicitly clean both sets of ARM_ASM.
