sfinfo - display information about audio files

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.

–help, -h
