Why if I import ac3 on premiere and export to audition for editing, it create wave file without turn off DRC??? It is a big error, DRC must be disable!!!!
Thanks for link but exist other methods more easy as libavcodec of directshow/ffmpeg
DRC: dinamyc range compression
Dolby use it for encoding audio but for editing is necessary turn off before of decoding to wave. Premiere dont do it and is a error but the audio generated will be deformed or corrupt.
To the best of my knowledge, MP3s do not include effects that can be "turned off" or otherwise adjusted after the fact. If an effect or filter was applied during the creation of the MP3, it's baked in and you can't remove it.
Maybe I dont explain properly. Adobe Premiere uses license of Dolby therefore uses his encoder/decoder. DRC is a parameter of decoder, if drc=true (on) then this effect is aplied to audio. On edition of audio the use of DRC isnt correct. This effect is used in media players too and maybe his uses is more properly, although not ever. Personally I dont like have my audio limited in volume.
One way for solution is:
1. First remove dialog normalitazion
2. Use this code with ffmpeg tools:
ffmpeg -drc_scale 0.000000 -i sound.ac3 -f wav sound.wav
