sfinfo [options] audio files...


sfinfo prints information about the specified audio files, including file format, sample rate, duration, and audio data format.

By default sfinfo displays information in a longer, multi-line format; specifying the --short or -s option produces a short, single-line summary.

Any files which are not recognized as valid audio files will be ignored unless the --reporterror or -r option is given. The file formats currently supported by sfinfo are AIFF, AIFF-C, NeXT/Sun .snd/.au, WAVE, Berkeley/IRCAM/CARL Sound File, AVR, Amiga IFF/8SVX, Sample Vision, Creative Voice File, NIST SPHERE, and Core Audio Format.

--reporterror, -r

Print an error message if any of the specified files are not recognized as valid audio files.
