qwavsilence

qwavsilence detects and shrinks silence sequences in wav files

synopsis

qwavsilence option... file...

description

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

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.
