Pre-Gap Concern

I have a CD that has a 3 minute gap before the first song.

The gap however really contains nothing, cept for near the end a backwards trumpet note.

Normaly i extract my music as a image and then cut the wav with a cue sheet, using the with gaps option.

The way I extract now usually gets everything, but now i am concerned.  Since most gaps at the start are 2 seconds, the only time the cue sheet displays any time there is if it is more than 2 seconds, such as 2.33 seconds.  Since this is usually silence, when you reburn it using the cue sheet, i'm guessing that the program just puts silence there.

But with this cd i have, i am almost certain i will lose that "musical" data, even though you don't hear it normaly during playback.  I really don't care about the sound snippet that i will lose, but it poses this question...

Has anyone found a cd that has a gap before the first track that does contain real music?

Thanks.

Yes.
In 1996 they issued a compilation of songs "Inspired by the show" X-Files.
It is called "Songs in the Key of X".
It has TWO songs before the first one starts. The only way to listen to those is hitting the "rewind" button until the start of the first hidden track.

If you extract those CDs with EAC's make image and cue-sheet feature, you won't lose any musical data at all.
And you should be able to burn it right back on another CD.

Thanks, i knew their had to be a cd out there like that.

Here is something else i am having a problem with.

I would like to extract the cd image and create cue sheet.  Then i usually split the wav by cue with gaps.  (I'd use corrected gaps, but then aren't the gaps at the start of the songs instead of at the end?) then I usually erase the image, and keep the individual wav's.  However, when i recombine the wav's, and then use the cue sheet, the last song on the burned cd is always short.  it's always short by the amount of gap after the inital 2 second gap.

For example "Cloud Nine" has 2.44 seconds in the starting gap.  After i do all my stuff and try to reburn it with a single wav and the cue sheet.  the last song is always short by .44 seconds.  I can't figure out why... has anyone encountered this problem before?

Thanks

I am trying a different method at this moment.  I'll post if that works.

Could it be cause my drive can not over read into the lead out?  Since i am using a + offset...

For an offset to read .4 seconds off, it would have to be HUGE.
I think that is not the problem, but I don't really understand what the problem is.
If you could try to explain yourself better, maybe I could try to help you.
Burning CD's using CUE files does not "delete" any data at the end of the files. This is simply not possible.
So the problem must be at extraction.
But please, try to explain better.

I'm sorry, but I have to add a Kylie Minogue album to this list.

I think it was 2001 Fever - the first track looked like it started at 0:00, but you could rewind before the 0 mark, and get an entire 4 min song - I think this was named "password" at some point.

Don't ask why I've got the CD though...

I mentioned it in another thread, but Factory Showroom by They Might Be Giants has a one minute song "Token Back to Brooklyn" hidden in the pre-gap (most CD players won't play it, but some will by rewinding past the first track, and I've ripped it with cdparanoia).
I am *expanding!*  It is so much *squishy* to *smell* you!  *Campers* are the best!  I have *anticipation* and then what?  Better parties in *the middle* for sure.

Arg, I have that CD ripped, and I missed that  .  Will have to re-rip probably (are you talking about the US version or other version? - US versions always seem to be missing the cool extras  )

David Gray's White Ladder cd has a hidden track called "I Can't Get Through to Myself" that begins before track 1.  You have to rewind past 00:00 on your player to listen to it.  No big loss though if you miss it during ripping.  IMO the album's fine without the hidden track.

Mayhem - Grand Declaration Of War also has a hidden track prior to track 1, but it isn't too interesting, either (it's the last song played backwards  )...

Yup, there definitely are two songs there.
Although the TOC shows something different.

See the over-9 minute pre-gap?
That's were they are.
9 minutes sure is enough for two songs.
You can use EAC to extract "index-based" all the data in those 9-plus minutes, and then a Wave Editor to split the data. That way you can access those songs at any time you want.
I don't remember them, though. I listened to that CD day and night when it came out, but when I got fed-up with the X-Files, it got buried in the deepest part of my collection. Has not came out since. I found about those songs way later. I remember them not being particularly good. Where they?

"Meesa sea them-a. Meesa not-a dumb-a, meesa only pointinga outa that-a..."

...this particular cd violates common sense, in that there is nothing it the TOC separating the two tracks in the "truly hidden" pregap of the first track.
So you can't really seek to the second hidden track without modifying the TOC.

Annoying.

Except you can't "access those songs at any time you want", because only the first hidden track can be sought to.
EDIT: Oh, split them in a wave auditor. OK.

Nope, they wreck the catchy "whistle-melody" in the intro of the cd.

Lit's CD "A Place In The Sun" has a 1:50 hidden track.  It's not a full song more like an intro to the album (no words just guitar and drums.)

I extract into individual files.  So the only way for me to get this track is to extract this album using "Append Gaps To Next Track" correct?  Let's say I use this (and the appropriate CUE sheet) in the future to burn a copy of the CD.  The copy will be slightly different than the original in that the track times will not be exact, right?  Are there any other issues I need to watch out for?
