Actual Bits of CD original encoding



This is a bit of a strange question. When a CD is burned, the bit rate
of the files (music) is set by any encoding software...and when I
download or rip I NOW decode wav to mp3 at either 256 or 320 bits.
When I re-encode...if I choose is to a CDA coding consistent
with CDs read by CD ROM devices.

My question is, if I have a burned a cd in a CDA format, then, when it
is re-ripped, I select it to come out as wave file. I can then encode
the wave to any level mp3 bit rate I wish.( I am doing this because I
am converting my CD library back to MP3 for that fantastic toy called
iPod and mobility.)

so, I have long since lost the info relating to the initial burn
resolution and I would like to re-concstuct or recapture the inherent
underlying bit rate of the inital rip. If it sounds confusing, the
purpose is to re-place files ripped when I naively thought 192 was
good enough. My ear is good enough to hear the difference between low
bit rates and higher bit rates in classical music. sometimes the older
performances have been ripped from vinyl and it is doubtful that
anything above 192 is necessary..but I have been surprised that some
pretty old mono vinyl can really be better at 256 bits.

Any thoughts on this??



Your ears, your pleasure! Suggest before ripping, converting or whatever
pleases your ears, make a copy of the music first. Then use that copy for
alterations. That way if you screw it up, you'll always have the original to
go back to. Happy putering :~)


Well, this is a barn door closed after the animals have escaped. The
original MP3 or FLAC files are long gone. I take it that the
underlying encoding is forever lost by any subsequent
resolution...bits used for encoding? I thought so but there are so
many little tricks and tools showing up that I was hopeful. Nyqist
sampling is the minimum bit rate for recovering all information,
whatever that means for is in the ear of the beholder, as
you say.
