[FFmpeg-devel] [PATCH] avcodec/dcaenc: Use aac psychoacoustic model for dcaenc

[Даниил Чередник]

There are several reasons to replace dca psychoacoustic to common model:
 - dca psychoacoustic has some quality problems especially at high
frequency bands
 - unclear implementation
 - aac implementation allows to use tonality measurement for future
improvements
 - a bit faster

AAC psychoacoustic uses float sample format, so first patch changes dcaenc
input format to AV_SAMPLE_FMT_FLTP.
Second patch replaces psychoacoustic model.
