qwavsilence - detect and shrink silence sequences in wav files

dmanye@etse.urv.eshttp://www.etse.urv.es/~dmanye/quelcom/quelcom.html

       tests has been done only with 44100 Hz 16 bit stereo files, though it may work with mono/stereo 8/16 bits
       files.

qwavsilence reads a list of wav files looking for silence sequences.

       the following modifiers are provided:

       j      value is interpreted as milliseconds.

       m      value is interpreted as minutes.

       s      value is interpreted as seconds.

       b      value is interpreted as bytes.

       k      value is interpreted as kbytes (1024 bytes).

       M      value is interpreted as megabytes (1024 kbytes).

       in either case, the values specified will be rounded to get an integer number of samples.

-d <duration>[<format>], --duration=<duration>[<format>]
              duration  is a positive integer that specifies the minimum duration of a silent sequence on a file
              to be reported. the value is treated as a sample number unless a format specifier is used. see the
              FORMATS section below for information. the default value is one second.

       -h, --help
              show a brief help and exit.

       -S, --shrink
              when this option is set, all the silent sequences greater than duration will be shrinked  down  to
              duration and the file size truncated accordingly.

       -t <threshold>, --threshold=<threshold>
              threshold  is  a percentage value respect the maximum (absolute) sample value. samples whose value
              is under the given threshold are considered silent. for example, a  value  of  2  means  that  all
              samples  with  absolute value under the 2% will be treated as silent samples. the default value is
              0.

       -v, --verbose
              show more detailed info.

       -V, --version
              show version and exit.
