I want to know the answer to the following question:
It is easy for a prospective user of an encoder to research the best choice because of what factor?
All the background I'm provided with is that "The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard.". Is that enough to answer the question?
Answer: no
