sndinfo(1) Displays information about a soundfile. .


Get basic information about one or more soundfiles.


csound -U sndinfo [options] soundfilenames ...

sndinfo [options] soundfilenames ...


sndinfo will attempt to find each named file, open it for reading, read in the soundfile header, then print a report on the basic information it finds. The order of search across soundfile directories is as described above. If the file is of type AIFF, some further details are listed first.

There are two option types:

1. -i or -i1 will print instrument information, which includes looping. The option continues until a -i0 option.

2. The other option is -b which prints the broadcast information for WAV files. It can similarly be negated with -b0.


csound -U sndinfo test Bosendorfer/"BOSEN mf A0 st" foo foo2

where the environment variables SFDIR = /u/bv/sound, and SSDIR = /so/bv/Samples, might produce the following:
