Complete Version history / Release notes / Changelog for eac3to

UsEac3to New version 1.3.0

- v1.3.0 2020-08-03 Incluided mlp.exe (Extract TrueHD from .mlps, see 1.2).
Improved include of FFMPEG functions (see 2.1 y 2.2).

UsEac3to New version 1.2.9

Some bug corrected and improved 'A/V Recode' to make easy filter and recode audio with ffmpeg.

Some samples of audio filters:

Downmix: -af "pan=stereo|FL<FC+0.70*FL+0.30*SL|FR<FC+0.70*FR+0.30*SR" [or other]
Resample: -af aresample=48000
Speedup: -af atempo=1.042708 [23.976->25], 1.041667 [24->25], 1.001 [23.976->24]
Slowdown: -af atempo=0.959041 [25->23.976], 0.96 [25->24], 0.999001 [24->23.976]
Delay: -af adelay=1500|0|500|0|500|500 [one delay for each channel]
Trim: -filter_complex "[0]atrim=2:8[a];[0]atrim=12:18[b];[a][b]concat=n=2:v=0:a=1"
And a sample of use in the image:

1) Load a mp4 in UsEac3to, ignore the non supported message.
2) Click at 'MkvExtract/INF' and ffmpeg inform:
3) The mp4 tracklist. We need recode the aac 44.1 KHz to 48 KHz and half volume.
4) We can extract the aac track, but is not necesary and close the dialog.
5) We put the ffmpeg filter: -af "volume=0.5, aresample=48000"
6) Click at 'A/V Recode' to open the dialog.
7) Select track 1 in 'map:X' or other like we see in 3)
8) Select 'Add to DEC' to add the filter.
9) Select ENCODER and quality.
10) 'Run' or 'EnQueue'
