NAME
sfinfo - display information about audio files
SYNOPSIS
sfinfo [options] audio files...
DESCRIPTION
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.
OPTIONS
--short, -s
Print short single-line summary of each recognized audio file.
--reporterror, -r
Print an error message if any of the specified files are not recognized as valid audio files.
--help, -h
Print help message.
--version, -v
Print version information.
EXAMPLES
Display summary of an audio file:
% sfinfo drum.aiff
File Name drum.aiff
File Format Audio Interchange File Format (aiff)
Data Format 16-bit integer (2's complement, big endian)
Audio Data 1569972 bytes begins at offset 54 (36 hex)
2 channels, 392493 frames
Sampling Rate 44100.00 Hz
Duration 8.900 seconds
List all recognized audio files in the current directory using the short output format:
% sfinfo -s *
9.60s 44100.00 aiff 1ch 16b -- bass.aiff
8.90s 44100.00 aiff 2ch 16b -- drum.aiff
