  1. hey there,
    as this isn't possible in EAC3to but works like charme in ffmpeg I just noticed something weird after updating it. When converting a 1 channel audio to a 2 channel one it automatically reduces 3 db. They seemed to change that after version 4.4. At least it is in 5.0, 5.1. and the latest 5.1.2
    So I'm curious if there is a way to disable it. Shure I could just apply +3db with something like -vol 576 but I don't want it to reduce 3 db and then add them, I would
    rather like to not reduce or add any db at all so that the 2 Channel version has the same db in each channel as the 1 channel one has.

    this is my command line:
    Code:
    -i %INPUTFILE%   -acodec pcm_s16le -ar 48000 -ac 2 -f WAV %1%.wav
    Maybe someone knows a "disable automatic decibel regulation" command. I couldn't find anything in the documentation
    thanks guys

    Do not use -ac 2, use filters directly. Like: -af "pan=stereo|FL=c0|FR=c0"

  6. btw 3dB reduction is mathematically correct from perceived loudness perspective - if you will not reduce level by 3dB then perceived loudness will be twice higher.
