It took a long time but once done, it's done for good. Meaning I've just done 
the manual adjustment route.

I went through my tracks one by one and looked at them on a VU meter (not peak 
meter and no normalisation), jumped the more louder part of the track then just 
applied the amplitude (usually -5 to -8dB depending on CD) to the track until 
the meter was close enough to 0dB and the tracks sounded roughly the same as 
the last one.

But I do that back in Windows since my favourite audio editor is win32 only. I 
then import the final product in to Rivendell without any further tweaking.

I use the free standalone VU meter made by the guy that made VU Player for 
windows to run along side of my editor, so I don't need to be near a mechanical 
VU when roughly setting the volume of a track. I use a -16dBFS 1KHz sinewave to 
calibrate the VU meter to 0dB since lower end pro cards can only produce about 
20dBu (like ASI5111, takeaway 16dB = +4dBu normal average operating level). 

This pings the Rivendell meter about +4dB on average. But high end cards sport 
+24dBu so there's 20dB of headroom and therefore you can use -20dBFS tone to 
align them instead for +4dBu average output.

It sounds like a lot of work, but because I've done my whole library like that 
now, it only takes an extra 3-4 seconds when importing a track for me.

  Hello folks!

  I know this question has been here before and some of you have a particular 
point of view about normalization as a way to keep levels (peaks) at the 
desired numbers for technical and security reasons, as avoid clipping.

  But at the same time, once we use peak normalizing there will be a great 
loudness difference between the songs, and it's not good when you have no 
operador to bring the faders up and take them down.

  To work around this situation I have been using the normalize function to 
keep the peaks at -13db and manually set the play level gain according to the 
necessary for each song, sometimes reaching more than 5db of gain.

  How do you people handle this?

  I'm thinking about writting some code to analyse the wav files from Rivendell 
and put a value in the play level using mysql, so they would have allmost the 
same loudness, and my processor (no AGC here) would work better. 

  Would it be useful somehow?

  Opinions are always welcome! 

  Regards,








  Atenciosamente,
