NAME

       qwavsilence - detect and shrink silence sequences in wav files

SYNOPSIS

       qwavsilence [option]... file...

DESCRIPTION

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

OPTIONS

       -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.

FORMATS

       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.

BUGS

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