    Question Rip copies that can be burned as original

    I am using dbPA -Paid- to rip my boyfriend's collection. I have run some trials and found dbPA to be the BEST ripping option but I have some questions.

    My goal is to rip each disc in a way that it can be burned back to disc as a copy of the original. The idea here is that I will probably be tossing most of the CDs and want to be able to reproduce the original if I need to. The copy should be recognized as the original in any program that uses Gracenote, AMG, etc. to retrieve track information for an audio CD.

    To be clear I am talking about Audio CD's only. Doing this for mixed CD's with CD-ROM content or other anomolies is a totally separate problem.

    From what I've read the most space efficient way to do this is by using a single FLAC plus CUE. I also know that this is not currently supported by dbPA. (Spoon you need to hurry up with that CUE implementation... I vote to increase priority for CUE support)

    So, is there a way to create this kind of copy? Space efficiency doesn't really matter at this point as long as I can convert to FLAC plus CUE at a later point without re-ripping. If I rip the CD to an ISO can dbPA "rip" and encode tracks from a virtual drive? (I don't really want to do that because dbPA has such good error correction capabilities.) Will RIP AS ONE be sufficient for this purpose?

    Other solutions are welcome.

    Indeed Rip as one will not write the cue sheet, so currently is not possible.

    I don't think you can rip an audio CD as an ISO, but Daemon Tools can mount a .wav/.cue combination which dbPowerAmp can rip. (The offset is 0 in my experience, although my "key disks" weren't recognised).

    You can use Exact Audio Copy to create the .wav/.cue combination.

    However, the solution I have to the problem you mentioned is to rip as tracks to a lossless format (FLAC will be fine, I use WMA Lossless) with pregaps appended to the next track (I'm pretty sure this is the dbPowerAmp default. Then I use Exact Audio Copy to create a .cue using the Action > Create CUE Sheet > Single WAV file ... option. (It doesn't matter if the any track information that it downloads is not correct.)

    In the future, if I want to recreate a CD I will have to convert the WMA lossless files to .wav, then join them together, and then almost any CD Writer app will be able to create a "clone" CD using the .cue file.

    Thanks for the reply sjmac.

    I think I'll use your method until CUE support is added to dbPA. But why exactly are CUE files necessary to recreate the original? Is it just for the TOC on the CD?

    If so, one could theoretically take a 49:15 length wave/cue, replace the WAVE with a silent WAVE of the exact same length and burn a disc that will be incorrectly recognized as an original/exact copy.

    Yes. This is because the most commonly used disc lookup services do not look at the audio itself, just the placement of the audio organization marks on the disc.

    Ok...

    So I think I've got it all down. Unfortunately that means popping about 100 cds back in the drive to get a CUE. But such is life.

    Also, just to be sure. If I rip to multiple FLAC files (assuming gaps are prepended) then decoding to WAVE and joining the files will give a WAVE exactly as if it had been ripped as whole off the original disc? I imagine that different implementations of this procedure could produce differing results. Will it really matter what I use to decode and join?

    No, you assume that gaps (which in some cases aren't silent!) are at the *end* of each track. This is almost always what you want unless you find a CD with a whole track hidden in the gap before the track 01.

    Yes

    I hope that if I do it properly it will always be the same. I've ripped to a lossless format, so it should always decode to the same .wav file whichever tool I use. I've not ever actually tried to restore a CD yet, so YMMV!
