3.6 qwavsilence

qwavsilence detects and shrinks silence sequences in wav files

3.6.1 synopsis

`qwavsilence option... file...'

3.6.2 description

qwavsilence reads a list of wav files looking for silence sequences longer than a given value, possibly shrinking them.

3.6.3 option list

`-d cutpoint'
`--duration=cutpoint'
cutpoint (see cut points) specifies the minimum duration of a silent sequence in a file to be reported. the default value is one second. this option overrides the option --length explained below.
`-h'
`--help'
show a brief help and exit.
`-l time'
`--length=time'
time (see specifying time) specifies the minimum length(=duration) of a silent sequence in a file to be reported. this option is quite similar to the --duration option above. it's easier to use though not as powerful than the previous one. the default value is one second. this option overrides the --duration option explained above.
`-S'
`--shrink'
when this option is set, all the silent sequences greater than the value of the --duration option 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 also sample information.
`-V'
`--version'
show version and exit.
