* AAC Encoder: clipping avoidanceClaudio Freire2015-07-27
| | | | | | | | | | | | | | | | | 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>

* aac: add additional fields needed by the encoder for intensity stereoRostislav Pehlivanov2015-06-28
| | | | | | This commit adds additional fields which are used by the native encoder to add intensity stereo support. It also adds some clarifying statements to the comments for the codebooks. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* aacenc: Adjust the initial offset for PNS valuesRostislav Pehlivanov2015-04-14
| | | | | | | | | This commit adjusts the intial offset for PNS values, introduced with commit f7f71b5795d708763eb0c55fe5e2cb051b2b69f4 earlier. This commit shifts the value in such a way that no further offsets are required in the aaccoder.c file. Earlier version of the PNS patch had 2 offsets in both the aaccoder and aacenc.

* aacenc: Add support for Perceptual Noise Substitution energy valuesRostislav Pehlivanov2015-04-13
| | | | | | | | | | | | This commit implements support for writing the noise energy values used in PNS. The difference between regular scalefactors and noise energy values is that the latter require a small preamble (NOISE_PRE + energy_value_diff) to be written as the first noise-containing band. Any following noise energy values use the previous one to base their "diff" on. Ordinary scalefactors remain unchanged other than that they ignore the noise values. This commit should not change anything by itself, the following commits will bring it in use. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* AAC: Fix M/S stereo encodingClaudio Freire2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a pointer arithmetic bug in adjust_frame_information that resulted in heavily corrupted audio when using M/S encoding. Also, a backup copy of untransformed coefficients has to be kept around or attempts at re-processing the frame (which happens when hevavily overspending bits during transients) will result in re-encoding of the coefficients and subsequent corruption of the resulting stream. A/B testing shows the bug as corrected, but still cannot prove that M/S coding is a win at least in numbers. Limited listening tests do show improvement on M/S encoded samples in lower bitrates, but they're hidden among the other artifacts that remain to be corrected in the encoder. Some of the regressions flagged in the report do show poor stereo image (but not buggy), so M/S encoding is clearly not good enough yet to be defaulted to auto. In numbers, Patched against Unpatched, stereo_mode auto: Files: 114 Bitrates: 6 Tests: 683 Serious Regressions: 0 (0%) Regressions: 0 (0%) Improvements: 227 (33%) Big improvements: 92 (13%) Worst regression - mybloodrusts.wv - 256k - StdDev: 28.61 pSNR: -0.43 maxdiff: 1372.00 Best improvement - 60.wv - 384k - StdDev: -369.57 pSNR: 45.02 maxdiff: -13322.00 Average - StdDev: -80.56 pSNR: 2.49 maxdiff: -8858.00 Patched against Unpatched stereo_mode ms_off shows no difference.

* | aacdec: add support for dual mono in Japanese DTVAkihiro Tsukada2012-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Japanese DTV uses some non standard extensions in AAC audio. One example is 'dual mono', which combines two independent audio into one stereo stream, storing them in left and right channels respectively. Historically, dual mono audio has been used for multi-lingual audio, one for local/native language, and another for english, and usually the "main" (local language) channel should be output without any user interactions. The frames of those dual mono audio are allowed to set ADTS channel_config field to 0, and just contain two SCE's *WITHOUT* PCE, which is a non standard extension by Japanese DTV standard. (ref. ARIB STD-B32 PartII 5.2.3) This patch adds an AVPacket side data, AV_PKT_DATA_JP_DUALMONO, which indicates that the AVPacket is likely to contain an audio frame with the above dual mono extension, and has the parameter to specify the desired channel selection in that case. It also makes aacdec to detect dual mono and output just the desired channel when this side data is attached.
