Rostislav Pehlivanov	4f396a6f30	fate: temporarily disable AAC TNS test Fixing it will take a bit longer, so just suspend the test. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	ae1b9c9754	fate: added PNS, TNS and IS tests for the AAC encoder This commit adds tests for the PNS, TNS and IS functionality of the encoder. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Claudio Freire	59216e0525	AAC Encoder: clipping avoidance Avoid clipping due to quantization noise to produce audible artifacts, by detecting near-clipping signals and both attenuating them a little and encoding escape-encoded bands (usually the loudest) rounding towards zero instead of nearest, which tends to decrease overall energy and thus clipping. Currently fate tests measure numerical error so this change makes tests using asynth (which are near clipping) report higher error not less, because of window attenuation. Yet, they sound better, not worse (albeit subtle, other samples aren't subtle at all). Only measuring psychoacoustically weighted error would make for a representative test, so that will be left for a future patch. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Claudio Freire	84f4be424d	avcodec/aacpsy: Fix AAC Psy PE reduction calculation when multiple iterations are required This is a small change, but it does have a big impact on bit allocation. all the regressions marked in the report have no audible difference (I didn't check them all though), but the improvements can be heard. This affects mostly high bit rates. It's related to issue #2686. In the report, A is the patched version, B is unpatched, all comparisons show deltas in the form (A-B), so a positive pSNR delta means a better quality in the patched version, and negative a regression. Regressions are only considered for pSNR deltas below -1db, they're considered serious below -6db. All measurements were done with tiny_psnr. The summary of the report inline for quick reading: Files: 58 Bitrates: 6 Tests: 347 Serious Regressions: 0 (0%) Regressions: 10 (2%) Improvements: 54 (15%) Big improvements: 26 (7%) Worst regression - sine_tester.flac - 384k - StdDev: 1.68 pSNR: -3.05 maxdiff: -178.00 Best improvement - 07 - Bound.flac - 384k - StdDev: -1700.05 pSNR: 20.64 maxdiff: -29595.00 Average - StdDev: -55.67 pSNR: 1.20 maxdiff: -1593.00 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
