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.

2013-11-19Adds functions for multistream padding/unpadding and single-stream unpaddingJean-Marc Valin
These are all completely untested.

2013-11-18Adds SATURATE16() to the fixed-point debug build tooJean-Marc Valin
2013-11-18Fixes SILK surround calibration while fixing other MSVC warningsJean-Marc Valin
2013-11-17Add some basic testing for OPUS_{GET|SET}_PREDICTION_DISABLED.Gregory Maxwell
2013-11-16oops, fix previous commitJean-Marc Valin
2013-11-16Make CELT_PVQ_U_ROW staticJean-Marc Valin
2013-11-15Adds OPUS_SET_PREDICTION_DISABLED() ctl to force "independent" framesJean-Marc Valin
Works by turning off pitch and energy prediction in CELT, while setting first_frame_after_reset in SILK to disable pitch and LSF interpolation and reduce LPC gain.
2013-11-15Adds a simple padding test to opus_demo (disabled by default)Jean-Marc Valin
2013-11-15Oops, missing semicolon on RESTORE_STACK in previous commitJean-Marc Valin
2013-11-15Adds missing RESTORE_STACKs in celt_encode_with_ec()Jean-Marc Valin
2013-11-15Fixes a bug where the encoder was trying to use redundancy in CELT modeJean-Marc Valin
The problem was that forcing CELT-mode for low bitrate CBR was done too late, after the encoder had decided to use SILK. This was causing redundancy to be allocated because the encoder didn't realize it was going to keep using CELT.
2013-11-14Adds packet padding that works for all codes and fixes 40/60 ms CBR.Jean-Marc Valin
Padding is now handled by the repacketizer.
2013-11-14Fixes max_redundancy so that hybrid CBR can fill all bytesJean-Marc Valin

2013-11-13Variable frame size fixes (still not exposed in the API)Jean-Marc Valin
This fixes an actual error in the downmix (using the float version even for the int API), as well as a bunch of conversion warnings.
2013-11-13Making the CELT fixed-point decoder a bit more robust to extreme signalsJean-Marc Valin
denormalise_bands() can now produce signals close to the max MDCT amplitude.
