I want to know the answer to the following question:
Aside from silence, which sections of music highlight parts that are easier to compress?
All the background I'm provided with is that "Users who know a particular "quality setting" that is transparent to their ears can use this value when encoding all of their music, and generally speaking not need to worry about performing personal listening tests on each piece of music to determine the correct bit rate.". Is that enough to answer the question?
