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.
