Hi everybody!
First of all will you please accept my apologizes for my language.
Think I speak english like a french cow...

I'm a newby in DAE and use EAC for few days. And i have to tell that I don't really understand the goal of all the options presented in the ACTION menu...
But this is not the question.

The first thing I've tried to do is to detect the gaps of my CD (ARCHIVE - Controlling Crowds). And I can't obtain twice the same lenght of gaps, nor the informations in the TOC alterations window.

I've tried all combinations between A, B & C methods and Accurate & Secure gap detection, tested each combination 3 times, and exported the result as Cue Sheet, in order to compare them quickly.

I've never be able to get two identical cue sheets...

Is it a bug in my configuration? Or maybe is it normal and I didn't understand the goal of gap detection?

I thank you to explain me what's wrong.


Precisions :
I've configured EAC with my hardware using the detections of the wizard.
My reader was in the DB (+6 offset)
I use AccurateRip
I work with XP SP3.

We have been given very little information about what EAC is doing in each of its methods (A, B, C), so it's anybody's guess as to why your results are inconsistent. I can only assume that sometimes the problem is the drive, sometimes it's the disc, sometimes it's EAC. I wish we knew more about what EAC does in each of its gap detection methods, and what it does when it tests detected gaps for silence, because all of these features seem to be unreliable.

What EAC is calling "gaps" are actually chunks of audio data which come right before each track's start position, and this audio may not really be silent, even when EAC says it is. So usually you should just leave settings at their defaults - "append gaps to previous track" - and don't even bother running gap detection at all. If you have problems with the results of ripping tracks this way, post more info about what you're trying to accomplish and why.

"So usually you should just leave settings at their defaults - "append gaps to previous track" - and don't even bother running gap detection at all."

Pardon me for hijacking this thread, but I would like to obtain some information about cue sheet generation in advanced mode.

In beginner mode there is just a single action you can take for multiple-file cue sheet generation: "Create CUE Sheet -> Multiple WAV files...".

I've noticed that the cue sheets generated in this mode will often start a new track with reference to the final second(s) of the previous file. That is, it will do something like:

This seems to work fine however, I have tested one such rip by burning it back to cd (with the tool called "Burrrn") and the tracks that were meant to flow together (continuous play) indeed played without a glitch.

After I changed the gap detection method from "method B inaccurate" to "method A accurate", gap detection and (hence) CUE sheet generation is going much faster than before, which is good. In one test, the cue sheet generated with the former method was only 0-2 frames "off" from sheet generated with the latter method, which seems to be accurate enough.

My question is really this: when I am using advanced mode, I get the option to choose between 3 types of multiple file cue sheet generation:

- with gaps (noncompliant)
- with leftout gaps
- with corrected gaps.

I don't understand what these options represent. My gaps are appended to the preceding tracks/files (as per the default). If anything, the tracks in the cue sheet should reference the preceding file, and in such a way that when written to disc, the original gaps (00 indexes) are recreated.

1. What do these 3 options represent?
2. Which option is the default option that you use in "beginner mode"?
3. Which option should I use, given that (upon ripping) I choose "append gaps to previous track"?

Greetings,
Dryden.

Since the OP is asking why his detected gaps are never the same size twice, but you're just asking for an explanation of the gap options for cue sheet generation, maybe you should move your post to a separate thread.

However I think the short answers are...

1. See the EAC gap settings and EAC and Cue Sheets guides in the Hydrogenaudio wiki.
2. with gaps (noncompliant).
3. with gaps (noncompliant).

Oh yes, I'm sorry, I think you're right. However since you already gave the answers, there's little use now to make a new thread..

So basically the 3 gap handling options are reflected one-on-one by the 3 cue sheet options.

Leave out gaps <-> Leftout gaps
Append gaps to previous tracks <-> With gaps (Noncompliant)
Append gaps to next track <-> With corrected gaps

So, thank you for your answer, and the links to that wiki! I also found another page that explains this very well:

I will now leave this thread then, and allow for the OP to continue his error discussion.

In general, it is the primary database that first discovers there is a gap. Every one minute, the primary database polls all of its standby databases to determine if there is a gap in the sequence of archived redo logs. This polling between the primary and standby database is often referred to as the heartbeat. This heartbeat is performed by the primary database serially. The DBA can always determine if there is a gap in the archived redo logs by querying the V$ARCHIVE_GAP view (from the physical standby database) as described in the next section.

steve7680768, you seem to be talking about something completely unrelated to Exact Audio Copy and its concept of 'gaps' on audio CDs. Why did you post that?
