* | aacenc_tns: tune and reduce artifactsRostislav Pehlivanov2015-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a couple of major changes here: 1. Start using TNS coefficient compression. 2. Start using 3 bits per coefficient maximum for short windows. The bits we save from these 2 changes seem to make a nice impact on the rest of the file/windows. 3. Remove special case gain checking for short windows. 4. Modify the coefficient loop to support up to 3 windows. The additional restrictions on TNS were something that was no in the specifications and furthermore restricting TNS to only low energy short windows was done to compensate for bugs elsewhere in the code. Overall, the improvements here reduce crackling artifacts heard in very noisy tracks. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | aacenc: remove the experimental flagRostislav Pehlivanov2015-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thiss commit removes the experimental flag from the native AAC Encoder and thus makes it the default. After a lot of work, done by myself and Claudio Freire, the quality of this encoder rivals and surpasses libfdk_aac in some situations. The encoder had instability issues earlier which prevented it from having its experimental flag removed, however the last commits done by Claudio removed the last known source of instability and solved a lot of problems which were previously observed. The issues were caused by the various coding tools interfering with the scalefactor indices. Thus, with these problems solved, it should now be possible to declare this encoder as the default and recommend that the users should use it instead of others provided by external libraries, as it is both faster and has a subjectively higher quality with selected tracks. The encoder has still yet to be fine tuned for every possible audio file type like music or voice, so it is hoped that with the experimental flag removed the users should be able to provide feedback and make the encoder better than the alternatives for every type of audio and at every bitrate.

Hasn't been updated for a very long time as well, hence it is more appropriate to remove it since it also depends on a big burden of a code (the encode_window_bands_info function which is just as old, just as unstable and bad and in no way modifiable or fixable).

* | AAC encoder: improve SF range utilizationClaudio Freire2015-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does 4 things, all of which interact and thus it woudln't be possible to commit them separately without causing either quality regressions or assertion failures. Fate comparison targets don't all reflect improvements in quality, yet listening tests show substantially improved quality and stability. 1. Increase SF range utilization. The spec requires SF delta values to be constrained within the range -60..60. The previous code was applying that range to the whole SF array and not only the deltas of consecutive values, because doing so requires smarter code: zeroing or otherwise skipping a band may invalidate lots of SF choices. This patch implements that logic to allow the coders to utilize the full dynamic range of scalefactors, increasing quality quite considerably, and fixing delta-SF-related assertion failures, since now the limitation is enforced rather than asserted. 2. PNS tweaks The previous modification makes big improvements in twoloop's efficiency, and every time that happens PNS logic needs to be tweaked accordingly to avoid it from stepping all over twoloop's decisions. This patch includes modifications of the sort. 3. Account for lowpass cutoff during PSY analysis The closer PSY's allocation is to final allocation the better the quality is, and given these modifications, twoloop is now very efficient at avoiding holes. Thus, to compute accurate thresholds, PSY needs to account for the lowpass applied implicitly during twoloop (by zeroing high bands). This patch makes twoloop set the cutoff in psymodel's context the first time it runs, and makes PSY account for it during threshold computation, making PE and threshold computations closer to the final allocation and thus achieving better subjective quality. 4. Tweaks to RC lambda tracking loop in relation to PNS Without this tweak some corner cases cause quality regressions. Basically, lambda needs to react faster to overall bitrate efficiency changes since now PNS can be quite successful in enforcing maximum bitrates, when PSY allocates too many bits to the lower bands, suppressing the signals RC logic uses to lower lambda in those cases and causing aggressive PNS. This tweak makes PNS much less aggressive, though it can still use some further tweaks. Also update MIPS specializations and adjust fuzz Also in lavc/mips/aacpsy_mips.h: remove trailing whitespace
