PROGRAM:
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.
