Topic: what the heck are "SBE's"??

[1westkc3]

I got SBEs on a Gourds show I taped.  I tracked a medly using Nero 7 Ultra.  I've used TLH to try to correct them but I still hear them.  Below is the log of the fixes TLH performed.  Any ideas why after the fix I still hear the SBEs?


The Gourds Tr22.flac --> The Gourds Tr22-fixed.custom
  - beginning of track will be moved backward by 2148 bytes
  - data size will increase by 1608 bytes

The Gourds Tr23.flac --> The Gourds Tr23-fixed.custom
  - beginning of track will be moved backward by 540 bytes
  - data size will decrease by 1008 bytes

The Gourds Tr24.flac --> The Gourds Tr24-fixed.custom
  - beginning of track will be moved backward by 1548 bytes
  - data size will increase by 468 bytes

Did you run the shntool test to see what it says?

[1westkc3]

If you're referring to the "Test Encoded Audio File(s)" tab in TLH, yes and the results state tested ok (file will decode properly. 
If this is not the tool you're referring to, please direct me to the location of the shntool.

"Audio File Details" tab - "len mode" (right hand side box)

Any help explaining what this means and what it idicates I need to do to fix the SBEs would be greatly appreciated.

The b means SBE.

The xx means the since it is flac it cannot be played on a cd-r

Thanks for the guidance pmonk.  It says;
 "An 'x' in any of these slots indicates that the particular problem does not  apply  to this file, or cannot be determined."  So I guess I can stop trying to fix it (at least with TLH).  Thanks again to both dorrcoq & pmonk for the assistance.

If you convert the flac to .wav, the xx will no longer appear.

TLH will fix the b

I had this problem once. I used cd wav to track, no post work, then flac frontend with the allign option checked. It showed sbe on the flacing and said something about moving a piece to the begining of the next track or something. I couldnt figure it out, so I deleted it, re-tracked it from the original wav and it was fine. Everything I have read tells me this shouldnt have happened with cd wav, but it did. Only 1 time out of 40+ shows though.

You're wrong there!  You still have SBE's, and you CAN fix them with TLH.  PM me your e-mail address and I will send you my SBE tutorial/

[Brennan]

+T for wanting to get your files correct!  I have pointed out SBE's to a few people on the archive, and got comments like "well, I can't hear them, so I don't care".  Come on!  This is the ARCHIVE!  Shouldn't all the files be as perfect as possible?

Good point, +T

I've been concerned about SBE's also, since I usually track on a standalone cd recorder (an HHb cdr-830). I transfer from dat > cd on the HHb as an all one track disc, then listen and make notes where to insert the track ID's from the all one track disc, onto the next disc with track ID's. Is that asking for trouble with SBE's, or just something that can fixed down the road?

Plus, the other big concern for me is that I use a Mac (MacMini G4), and I've never uploaded my standalone burned disc's onto the computer for normalizing,etc. I have Toast with Jam6. Is their a tutorial on this or another board that can help a slow computer person work with this software? Thanks

SBE's (sector boundary errors)
Tracking at Sector Boundaries

Paying attention to a simple technical issue during tracking can make a noticeable difference in seed quality. Each track of a standard audio CD is composed of "sectors" or "frames" that are each 1/75 second long (also expressed as 2352 bytes or 588 samples long). If a track is properly cut on a multiple of 1/75 second, it is "sector aligned", or cut "along sector boundaries." When it is not properly cut, the last sector is like a ragged end, which CD burning software just fills in with silence. Listeners will hear a click or pop between tracks because of the music -> sub-second silence -> music transition. This is extremely annoying and easily avoidable.

For Mac,
I use Peak pro 5.2, but you can get audacity freeware, and xact for SBE's

I have WaveLab and CuBase, but still prefer to use CDWave for cutting up CD tracks. With CDWave, cutting on correct sector boundries is fool proof. Just remember to cut the begining of the first file and the end of the last file with CDWav too.
