    FLAC Encoding

    Hi,

    With Exact Audio Copy (windows only) you can burn and compress to FLAC
    with one instruction. In that case you don't need the flac frontend.

    Please read http://www.saunalahti.fi/cse/EAC/index.html for instructions
    (scroll down to the flac instructions).

    Cheers

    Dolf

    Okay let's say, theoretically, that I was about to lose sleep over my

    google for it.


    Hey, don't feel bad, I had to redo 500+ CDs.
    My Kill the CD project has some notes I've made
    http://www.pfarrell.com/music/killthecd.html
    Flac is from sourceforge,
    http://flac.sourceforge.net/ But don't get it from there... because...

    Most Windows users want to use a GUI front end, FLAC is a shell program,
    or CMD program, or Unix-like command program. So for most Windows
    folks, it is pretty user hostile.

    I use FlacFrontend, available with Flac
    on http://members.home.nl/w.speek/flac.htm
    there are also links to Flacfrontend on the sourceforge site.

    Some tips are at

    EAC with flac is definitly the way to go. I did all mine that
    way.

    I've tried this but found it to be slow. EAC rips track-by-track and my
    CD drive spins down during the encoding step.

    It's much faster to extract all tracks and then encode. The trouble
    with this method is that EAC doesn't do the tagging unless you go
    track-by-track.

    Does anyone have a workaround that will get EAC to encode by disk after
    an extraction, or hints on how to get the metadata to persist in the
    extracted WAV files?

    Right, the extraction process is 5 to 10 times faster than flac compression.
    I extract all my files first, using CDex or EAC as my mood fits, and
    then use FlacFrontEnd to compress and tag them.

    FlacFrontEnd has a program that it uses that extracts metadata from
    the directory structure, or it can guess. The program is a shell program
    called tag.exe, flacfrontend calls it automagically.

    I generally extract for a couple hours and then compress all night.

    tag.exe also has file renaming and a few other tricks.

    It is not a one click process, whereas doing it all with EAC is one click
    and slow.
    I am willing to do the five click process to have it run faster. More
    importantly, I want extracting to be fast, since I'm there feeding in CDs.
    It can compress all night while I sleep.

    What?? You must have something configured incorrectly with
    EAC. I'm not sitting at home right now where it is installed
    so I can't tell you exactly where it is; but you can
    definitely have EAC rip all the tracks at once to wavs and
    cue for your compressor. That is the way I did all mine.
    When I was quick with the CD changes (and there were no
    occasional read errors and the cddb info did not require
    tweaking) I sometimes had 50+ tracks queued for FLAC.

    well the fact that it's possible is good news anyway. i'll take another
    look at the settings and see what i find. if you get the chance, you
    could maybe post a rundown of your config. thanks.

    You need a faster computer ;-). Actually the that's probably close
    to what I was getting if you don't count the CD change itself (or
    missing it by a few minutes) and tweaking the tags.

    As I mentioned EAC is capable of one-click and faster since it's
    all in one program. Perhaps you guys are using an old version
    of EAC? I will really have to look it up when I get home.

    I have come to the conclusion that it depends on the CD drive a lot. I have a
    fast computer with a 52X CD drive and it extract a full cd in about 5-7 minutes.
    I have an older PC with a 2X DVD drive and it whips out some cd's in about 2-4
    minutes. Of course, encoding on the older machine is painfully slow. I've
    found it faster to have the other machine connect and encode the file while they
    are stripped across the network. However, unless I had a huge backlog of
    encoding to do while I slept, it was just easier and overall faster to do it all
    on the newer PC. EAC makes it really easy. I had two drives, so I could have
    two session going for ripping, and set EAC to run 4 processes each for encoding.
    This way I could cue up a load of work and leave it going with all guns blazing

    OK. Some questions on the specifics of this:

    When you say "two sessions going", do you mean you have two instances of
    the EAC program loaded?

    Where/how do you configure EAC to use multiple processes for encoding?

    Does EAC not stop extraction while the external compressor is
    functioning? If not, how did you configure this behavior?

    Sorry to be so dense, but for me to clear my library I'll have to
    extracting/encoding ~1500 CDs. Process efficiency is going to be key.

    No, I don't yet have a storage solution in place. I've got 320GB inside
    the server box and will likely add 300GB external. That, combined with
    a DVD burner for offline archiving, should keep me busy for a while.

    yes, one set to read from each CD drive that I have installed. I have a burner
    and an older reader in teh same PC.

    its in teh preferences somewhere. I dont have it installed here, so I can't
    remember off the top of my head.

    I didnt configure anything specifc to this, to my memory. It just launches the
    encoder and a command window pops up. Its been a year since I did the task, so
    I may have, in reality, cued up several albums of wavs, THEN had EAC process them.

    ouch. I had about 250. It was digitising tapes that killed me. I ended up
    giving up and just downloading copies of ones I really wanted.
