What is the reason of non-constant compressing ratio in the voice
download mode?
VBR files vary the amount of data stored depending on the
complexity of a particular section of music, therefore the
compressing ratio is relatively smaller when compressing complex
music like classic, pop, etc.
Why is there quality difference between directly compressing CD
music and compressing by MP3 ?
MP3 is lossy compression method; it compresses with discarding
the inaudible sound. This method cannot preserve the exact CD
sound source, so the quality of sound compressed with MP3 is
worse than directly compressing CD music.
Can I save the file that is not music one?
It can be saved on the audio card, but not uploaded for protect
copyright. And already saved file(s) cannot be changed.
