I want to know the answer to the following question:
As a result of the freedom, different encoders can result in different quality even if which aspect of the file is the same?
All the background I'm provided with is that "Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded.". Is that enough to answer the question?
Answer: no
