Hi All
I'm using arecord to record directly to a USB key:
arecord -f cd > /mnt/usb/myfile.wav
But I see buffer overruns at 30 second intervals, which correspond with short bursts of USB write activity.
I'm assuming this is related to:

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 trun-
cated 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 sam-
ples. 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.
BUGS
tests has been done only with 44100 Hz 16 bit stereo files, though it may work with mono/stereo 8/16 bits files.
