SoXI — Sound eXchange Information, display sound file metadata
soxi [-V[level]] [-T] [-t|-r|-c|-s|-d|-D|-b|-B|-p|-e|-a] infile1 ...
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).
Set verbosity. See sox(1) for details.
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.
Show detected file-type.
Show number of channels.
Show number of samples (0 if unavailable).
Show duration in hours, minutes and seconds (0 if unavailable). Equivalent to number of samples divided by the sample-rate.
Show duration in seconds (0 if unavailable).
Show number of bits per sample (0 if not applicable).
Show the bitrate averaged over the whole file (0 if unavailable).
Show estimated sample precision in bits.
Show the name of the audio encoding.
Show file comments (annotations) if available.
Please report any bugs found in this version of SoX to the mailing list (email@example.com).
