There is a rapidly growing number of users who are editing audiobooks for Audible. Their ACX submission requirements have several standards that must be met - max peak of -3dB, max.min range of avg RMS for file, min noise floor, etc. There are SOOO much easier after editing an audiobook to have a tool that tells you if your audio passes the "ACX Check." It could be added to the Amplitude Statistics Window. Currently the only way to do this is to use the long-running free plugin that only works in Audacity (a 3rd party wrote this and thousands of people use it), and more recently, Sound Forge Pro 15, who have just added that capability.
