Saying goodbye is the only option available. By encoding music in lower
bit rates, a lot of stuff required to make it soothing to the ear has been
removed from the resultant file. Since missing parts can't be predicted
using some formula, one can't recreate original audio signals. Even if
some processing is done to remove the tinniness of voice, human
brain is sharp enough to detect the differences in the original voice and
the processed one.
Unlike predictable signals like a sine wave of given amplitude and
frequency, music consists of unpredictable signals. To store a
predictable signal of infinite duration, one needs negligibly small
amount of storage space. But for storing an unpredictable signal of
limited duration, one needs comparably larger storage space.
Looking at this issue from another angle; if we could
re-create the missing parts from a smaller file, then why do we need
a larger file in the first place? MP3 itself is a compressed audio
format where a lot of undetectable (for human ear) audio
signals are removed from the original using some sophisticated
filtering. But there are people who can detect the differences
between a CD quality audio and its MP3 form.
