util2/mixer/extract.c was not used by any build targets in SConstruct,
and the contents of the file seemed to be outdated (that is, it would
not compile). Additionally, there is a file xtrct.c that is newer and
appears to do the same thing, and is actually built. So, I made the
conclusion that extract.c is obsolete, and is replaced by xtrct.c.

xtract works on scores, extract workson sound files.

Really you should not delete things without discussion.

Wrong. Both files work on sound files, the only difference
is that extract.c is older and not used.
It is util1/sortex/xmain.c that extracts from scores.

According to my copy of Csound 5:

xtract.c works on soundfiles;
extract.c works on scores:

xmain.c calls  scxtract() defined in scxtract.c, which in turn calls extract() 
defined in extract.c.

Unless someone has decided to change it all, of course, my copy of Csound 5 is a 
  month old now....

To be more precise, Engine/extract.c works on scores, and
util2/mixer/extract.c (the file about which this thread is)
is a variant of xtrct.c, but is not used by the build system.
That's why I deleted util2/mixer/extract.c and kept xtrct.c.

Yes, but in Engine/extract.c, not in util2/mixer/extract.c.
