NAME    [Toc]    [Back]

     sfinfo - display soundfile	information

SYNOPSIS    [Toc]    [Back]

     sfinfo [ options ... ] soundfiles ...

     where options are:

	-short
	-reporterror

     The full option string need not be	specified; -s and -r will work.

DESCRIPTION    [Toc]    [Back]

     sfinfo reports information	about the soundfile(s) specified.  If invoked
     with no arguments,	it will	display	help.  If invoked like:

	sfinfo flute.aif

     It	will give you info in the format:


	Filename: flute.aif
	File Format: Audio Interchange File Format (aiff)
	Size: 32100 sample frames, 0.73	seconds, 64.6 Kbytes.
	Format:	1 channel 16-bit integer (2's complement, big endian) file.
	Sampling Rate: 44.100 kHz.
	Data begins at offset 402 (192 hex).


     If	you specify the	-short (-s) option, sfinfo reports information in this
     ls-like format:

	 tttt  sssss.ss	ffff  ccc bbb ee filename
	 0.73s 44100.00	aiff  1ch 16b -- flute.aif
	37.27s 22050.00	next  2ch float	 phone.snd

     Where:
	t is length of soundfile in seconds
	s is sampling rate of soundfile	in Hertz
	f is soundfile format
	c is number of channels	in file
	b is # of bits for integer or mulaw file, or "float" for
	  floating point file
	e is sample encoding, "--" for linear or "mu" for mulaw
	  (this	does not apply to floating point files)

     A good way	of doing a "soundfile ls" is:

	sfinfo -s *

     which looks like:

	 0.73s 44100.00	aiff  1ch 16b -- flute.aif
	 6.47s	8000.00	aifc  1ch 16b -- gunn.afc
	 6.47s	8000.00	next  1ch  8b mu gunn.snd
	37.27s 22050.00	next  2ch float	 phone.snd
	 1.53s 22050.00	next  1ch 16b -- vulc.snd
	 1.53s 22050.00	wave  1ch 16b -- vulc.wav

     This works	because	sfinfo ignores files which are not soundfiles.
     Therefore the above listing only includes files in	the supported formats,
     even if the directory included other files.

     The -reporterror option causes sfinfo to report an	error if one of	the
     files given is not	a valid	soundfile.  This may be	desirable if a given
     set of files must contain all soundfiles.
