[680b] Setting audio normalization level 0.0dB gets changed to None

Normalizing audio to -3dB works fine but choosing normalize to 0dB seems to be equivalent to No normalization and indeed editing the profile shows that the setting has been changed from 0.0dB to None.

Yes, that's a known issue. The work around is to set it to -3 db, export the profile to an xml file.

Then, using a text editor (Notepiad is fine), edit the XML changing:

<Normalize>-3.000000</Normalize>

to

<Normalize>-.01</Normalize>

Then Import the modified profile.

BTW, I personally don't recommend normalizing to 0 dBFS, which can still trigger minor clipping during playback when the digital samples are converted to analog.

I strongly suggest that audio NOT be normalized to 0. The industry standard is that 1 kHz tone is set at -20 db (peak, not VU, RMS, etc), with average peak material at -9 db.

This allows for headroom, for sections of the program needing to go above -9 db for short periods.

Also, if you normailze to 0, the perceived audio level can be different from program to program because of the peaks that are above -9db. If for example a program had a peak that went to -3 db and a different program that only peaked to -6 db, the -6 db program will sound louder than the - 3 db program.

Just a suggestion.

Um, what industry do you think I work in?

I just want my edited recordings so that they're not way quieter than all the other sounds that my PC makes.

Normalizing to 0 dbfFS is fine, although I think -3 dbFS sounds a little better because these less chance of accidental clipping, and you probably won't hear much of a difference.

You might want to consider one of the compression options which can make the soft parts louder and the loud parts softer.

I have no clue. Owners of VRD do not have to work in the industry. I don't.



Simple fix for that. Turn up the volume on the amp. :D
Well Duh.

Then if my PC makes another noise for some reason (skype call arrives, email arrives etc.) I'll be blasted out of my chair.

Having your HTPC also be your everything else PC will result in these issues. Another Duh moment... don't do that. There are many ways to play videos and not have the problems with system sounds affecting your viewing pleasure.

I'm sure that you understand that you'll only raise the level 3-6 db, which really is not that much.
