Just download and install "SoX" command line _sound_(exchange)_system_...

There is also a line using /dev/dsp in default 8000KHz sampling speed but I haven't tested it yet...

You will have to change the "demo" variable from 0 to 1 for /dev/dsp or -1 for SoX. If you use SoX then change the pointer to the correct absolute address of your install...

Colours changed and decided on going back to the default 80 x 24 Terminal size...

SoXI(1) 							  Sound eXchange							   SoXI(1)

NAME
SoXI - Sound eXchange Information, display sound file metadata SYNOPSIS
soxi [-V[level]] [-T] [-t|-r|-c|-s|-d|-D|-b|-B|-e|-a] infile1 ... DESCRIPTION
Displays information from the header of a given audio file or files. Supported audio file types are listed and described in soxformat(7). Note however, that soxi is intended for use only with audio files with a self-describing header. By default, as much information as is available is shown. An option may be given to select just a single piece of information (perhaps for use in a script or batch-file). OPTIONS
-V Set verbosity. See sox(1) for details. -T Used with multiple files; changes the behaviour of -s, -d and -D to display the total across all given files. Note that when used with -s with files with different sampling rates, this is of questionable value. -t Show detected file-type. -r Show sample-rate. -c Show number of channels. -s Show number of samples (0 if unavailable). -d Show duration in hours, minutes and seconds (0 if unavailable). Equivalent to number of samples divided by the sample-rate. -D Show duration in seconds (0 if unavailable). -b Show number of bits per sample. -B Show the bitrate averaged over the whole file (0 if unavailable). -e Show the name of the audio encoding. -a Show file comments (annotations) if available. BUGS
Please report any bugs found in this version of SoX to the mailing list (sox-users@lists.sourceforge.net). SEE ALSO
