## sndinfo

sndinfo — Displays information about a soundfile.

## Description

Get basic information about one or more soundfiles.

## Syntax

    csound -U sndinfo [options] soundfilenames ...

    sndinfo [options] soundfilenames ...

## Initialization

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.

## Examples

    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:

    util  SNDINFO:
         /u/bv/sound/test:
               srate 22050, monaural, 16 bit shorts, 1.10 seconds
               headersiz 1024, datasiz 48500  (24250 sample frames)

        /so/bv/Samples/Bosendorfer/BOSEN mf A0 st:  AIFF, 197586 stereo samples, base Frq 261.6 (MIDI 60), sustnLp: mode 1, 121642 to 197454, relesLp: mode 0
         AIFF soundfile, looping with modes 1, 0
         srate 44100, stereo, 16 bit shorts, 4.48 seconds

         headersiz  402, datasiz 790344  (197586 sample frames)

         /u/bv/sound/foo:
               no recognizable soundfile header

         /u/bv/sound/foo2:
                couldn't find

Here is an example of the sndinfo utility. It uses the file sndinfo.csd.
