SHNTOOL -FIX/-STRIP HELP [info]

This is correspondence I had with RainDawg regarding shntool. I hope the following will help those who've had similar problems.

[MY original PM to RainDawg]
I used the batch file command you showed me to use - I created unique batch files (yours and other ones I messed with for the output). none of them can fix the problem I have. below is the shntool -len results of the show I want to seed here very soon. the show's 10th anniversary is coming up on April 7. please take a look at these shntool -len results and tell me if there's a chance I could fix it.

(MSDOS message when using the command file you gave me to use for "shntool -fix") [ From This Thread ]
{and yes I changed it for a specific output}
shntool [fix]: error: everything seems fine, no need for fixing

what would I need to change in the batch command line (.bat) file to make it fix the error(s)? I read the rest of the thread I referenced above and I am well aware of the alignment shift after I fix, but as I said it says there's nothing wrong.



thanks for your help sir.

[RainDawg's reply to my PM]
Fix accounts for sector boundary errors. This file is showing the "e" error. In the shntool documentation at this link:
http://www.etree.org/shnutils/shntool/doc/TUTORIAL

You can see that "e" means that the header contains extra chunks. There are often the result of some extra data put in by an audio editing program or tagging program. It is not harmful and does not affect the audio, but is often proprietary data and as such not necessary.

To get rid of it, instead of using -fix, try using shntool's -strip command on that file. Note that this will change the "wholefile" md5 checksum of that file, but NOT the audio fingerprint (shntool md5) since no audio will be changed.

Also, please post questions like this directly into the technobabble forum because in PM, no one else can benefit from the discussion. When posted publically, others can read, comment, and learn from the information shared.

Anyway, let me know if this helps!
--------------------------------------------------------------------------------

....and now another question for RainDawg (or whoever else knows this):

since shntool's -strip command resulted in the proper (extra chunk) fix, [thus re-checking the files with the shntool -len command and everything is ok].

WHICH md5 should be included in a (possible) BitTorrent post 1. Audio Fingerprint md5 (aka shntool md5) 2. "wholefile" md5 checksum(s) [of the files]??

would not both be important? or am I speaking out of my a**? [thanks in advance for all of your help]
