Fixing Volume in audio book chapters

You may want to give a try to my plug-in that was discussed here:

That thread was intended to discuss a problem with Audacity 2.0.5 (fixed in v2.0.6), which you can ignore for now. But I think the plug-in may be suitable very well for your use case!

(Unlike simple “normalization” or “amplify” functions, this pulg-in will not apply the same gain to all samples in the file. Instead “quiet” parts will get more gain than “loud” parts, so the volume will be “harmonized”)
