I want to know the answer to the following question:
What does the standard ReplayGain allow a player to automatically adjust?
All the background I'm provided with is that "ReplayGain is a standard for measuring and storing the loudness of an MP3 file (audio normalization) in its metadata tag, enabling a ReplayGain-compliant player to automatically adjust the overall playback volume for each file.". Is that enough to answer the question?
Answer: yes
