Converting 'Normalize' (db) output to use with --scale (lame)

Could anyone tell me how to convert the oputput from 'normalize' (Decibels) to use with the --scale option in 'lame'

For example I have this 'normalize' output
Quote
[Bobby@NoIP]$ normalize -n 15\ - example audio.WAV
Computing levels...
level        peak        gain
-16,7914dBFS -1,0410dBFS  4,7914dB  15 - example audio.WAV


And I want to get a number out of this to use with the --scale option in the 'lame' encoder.

Any hints ?

WaveGain

I prefer foobar2000 Diskwriter with "Use Replay Gain".
These are essentially same procedure.

Yes, use WaveGain instead of normalize.
See this topic and this post in it.

You can use a simple shell script:

album mode:
Code: [Select]
GAIN=$(wavegain -a -p -x *.wav);
for all in *.wav
do
    lame --scale $GAIN "$all";
done

radio mode:
Code: [Select]
for all in *.wav
do
    lame --scale $(wavegain -p -x "$all") "$all";
done


or simply for a single file:
Code: [Select]
lame --scale $(wavegain -p -x file.wav) file.wav


Edit: radio gain is done for each file.

Thanks everyone who replied.  I'm encoding mostly speech CDs so I'l be using the "Albun mode" of WaveGain, neat tool but took a while to find
