The Decibel Level

Audible rejected my audio book because I peaked. Does Audacity provide a way to make the level stay at a decibel level?

See [u]Audiobook Mastering[/u].

…It’s easy to set the peak level with Amplify or Normalize, BUT any linear volume adjustment will change your RMS level and noise level by the same amount (dB). If you follow the above outline you’ll get both the RMS & peak levels in spec., and then you just have to work on the noise.
