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.
