* normalize the RMS volume of a group of samples
* max value of the loudest peak in the group doesn't exceed xxx db
* no limiting/clipping/compression
Imagine a (non-existent) command line such as:
$ normalize-audio --rms --max-peak=xxxdb --as-lossless-as-possible
note that with normalize-audio 0.7.7:
$ normalize-audio --peak --no-adjust
$ normalize-audio --no-adjust
result in exactly the same output:
level peak gain
-44.9045dBFS -26.6550dBFS 32.9045dB china-22in_zildjian-1.wav
-36.0490dBFS -18.3966dBFS 24.0490dB china-22in_zildjian-2.wav
-33.1798dBFS -14.9723dBFS 21.1798dB china-22in_zildjian-3.wav
-25.6555dBFS -5.5081dBFS 13.6555dB china-22in_zildjian-4.wav
-18.4676dBFS -1.4021dBFS 6.4676dB china-22in_zildjian-5.wav
-17.8024dBFS -0.0540dBFS 5.8024dB china-22in_zildjian-6.wav
In this case, the file with a peak of -0.054db is adjusted by +5.8db in both cases, resulting in clipping/limiting etc.
