Hello list,
libsndfile-info shows various useful information like the one at the end of this mail.
I have Sonatina Symphonic Orchestra waves here (violins 1) and a one note wave includes
"Midi Note", "Loop Count" and "Cue Start : 92078 End :
223977", which is the actual loop start/end
Is this custom data or does it follow a standard?
And no matter what, how do I write that into my own wave files?
I would prefer command line tools. But programming interfaces are fine as well.
sndfile-metadata-set --help
Usage :
sndfile-metadata-set [options] <file>
sndfile-metadata-set [options] <input file> <output file>
Where an option is made up of a pair of a field to set (one of
the 'bext' or metadata fields below) and a string. Fields are
as follows :
--bext-description Set the 'bext' description.
--bext-originator Set the 'bext' originator.
--bext-orig-ref Set the 'bext' originator reference.
--bext-umid Set the 'bext' UMID.
--bext-orig-date Set the 'bext' origination date.
--bext-orig-time Set the 'bext' origination time.
--bext-coding-hist Set the 'bext' coding history.
--bext-time-raf Set the 'bext' Time ref.
--str-comment Set the metadata comment.
--str-title Set the metadata title.
--str-copyright Set the metadata copyright.
--str-artist Set the metadata artist.
--str-date Set the metadata date.
--str-album Set the metadata album.
--str-license Set the metadata license.
There are also the following arguments which do not take a
parameter :
--bext-auto-time-date Set the 'bext' time and date to current time/date.
--bext-auto-time Set the 'bext' time to current time.
--bext-auto-date Set the 'bext' date to current date.
--str-auto-date Set the metadata date to current date.
Most of the above operations can be done in-place on an existing
file. If any operation cannot be performed, the application will
exit with an appropriate error message.
