dialnorm

[depressya]

hi... i have a few ac3 audio tracks on my hard drive with incorrect dialnorm -27. those audios sound distorted. is it possible somehow to correct dialnorm without re-encoding?
thanx.

You can cancel DialNorm with eac3to, but the DialNorm -27 can't produce distortion (only 4dB less volume).

thanx
i know that dialnorm -27 is such a normal... but...
- all other files sent to my pioneer info "dialnorm +4" and they played well
- only three files is marked as "-27" and sound is overload
- i tried to play this 3 on my PC and via the analog 5.1 played well also
- when i downmix this into 2.0 everything is fine again
- after extraction into 6 mono wavs from 5.1 ac3 - all off them is fine
- and after muxing those monos into 5.1 ac3 using by besweet i get ac3 without distortion with dialnorm +4 like others...


so... how to cancel DialNorm via BeSweet without reencoding? :)

Seems a problem with pionner device and DialNorm=0.
Maybe you can solve the problem with eac3to without reencoding (put DialNorm=-31 instead 0):
