Re: Sox marker handling Was: Re: merging mono files

Thanks Rick.

Whilst the software you mention looks interesting, it does not appear to carry the features I am looking for ie merging 2 mono wav files into one without losing loop and marker data.

You may want to look into Octave which is like a free version of Matlab I use it to batch process / create 1000's of audio files at once.  The time this takes will vary on the length and bit rate of your file.

Here's some simple examples.

I am able to process these files with Sony Soundforge. This software does not come free though. I need to simply copy and paste. So it is as easy as a-b-c as the saying goes. It's the sheer volume of files that is of concern.

If Sox does not preserve loops and cues yet.... then please add that to the
wish list. It would be very handy for several people doing serious digital
sound processing. :-)

I was thinking about the problem of markers in the file headers when
mixing files together, as Dr. Mark is trying to do. What if the
markers in the left channel and the right channel are not completely
identical? I think this is a more complicated task than just copying
input file markers to the output file when mixing.

Hi,

in that case I would propose to issue a warning and copy the markers
from one source - this can be achieved without understanding the markers.
A more elaborate solution could use both markers, but ommit markers
which are too close together. This, however requires extracting and
understanding the information of the markers.

Thanks for your Ideas Erich!

As someone else already said it is not precisely known how sox handles
markers, and I don't feel that it should become a marker editing/merging
application. Speaking of that, is anyone aware of audio editors / DAW
that do precisely that, eg. displaying markers and allowing user to
edit/rename them, espeicllay on linux?

Thanks!
Peter
