I like to split audio books into smaller parts of around 5 minutes. This enables me to fast skip forward or backward within the book with my car stereo. Very useful when you read the same book as eBook or listen to it on a different player ;-)

I'm using this command line to split the files: mp3splt -f -a -t 5.00

Works fine for almost all cases, but sometimes a file is split just a few seconds before its end, annoyingly creating a small trailing file of these few seconds. So I would like to use the "trackjoin" parameter to create files that are, for example, at least 60 seconds long. If a split point is closer than that to the end of a file: skip it.

If I understand well, the only issue here is with the last split file. All the other split files will most likely be more than 60 seconds long.

It is not very easy to introduce the 'trackjoin' parameter for the auto adjust option for the moment (because when splitting using silence detection, the split points are detected before the split and when using the auto adjust option, the point is adjusted while splitting).

What about "not auto adjusting" the last end splitpoint ?

Yes, it's only the last split that. All previous splits are fine. And it doesnt't have to be the "trackjoin" parameter, a new parameter for -a would be fine, too. ;-)

I guess you know roughly where you are in the file when you decide to create a splitpoint with -a. Couldn't you then check if there are less than x seconds left in the file and just skip that splitpoint? It doesn't need to very accurate.

Sorry for the late reply. I just wanted to finish an ongoing development before starting this. I am now ready to work on this. I was thinking about this issue ... in fact, this has nothing to do with the auto adjust option. Suppose that you don't use the auto adjust option, it is most likely related to the use of the -t parameter. Say for example if the input file has 16 minutes and 3 seconds, then splitting it at every 5 minutes will produce a last file of 1 minute and 3 seconds. Probably the best is to introduce an option related to -t for the minimum theoretical track length.

An option to request a minimum track length would be just what I need! Thank you for considering it!

I have implemented the minimum track length for the time mode split like this:

Hi,
 
Thank you!!!
 
I just tried it with the -a option like this:
mp3splt.exe -f -a -t "5.00>1.00" <file>

The test track is 50:04 min so it should skip the very last split. And it did!
Please get yourself a beer, I've just donated some money to mp3plt.
 
Frank

I am closing the issue because this is now in the released version of mp3splt 2.6.
