After a lot of experimenting over many years, I am at a loss for how I can achieve the following (without lots of "painful experimentation"):
 * 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

 -36.0490dBFS -18.3966dBFS 24.0490dB china-22in_zildjian-2.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.
