NAME
record - records *.wav files
SYNOPSIS
record [ options ]
DESCRIPTION
record records *.wav files in CD quality
(i.e. 44100 Hz, 16bit, stereo). It has a input level meter, which
might be useful for sound trouble shooting (check if the mixer
settings ok for recording from the TV card etc.)
OPTIONS
- -h
- display help text
- -o file
- basename for the output file(s), a number and the .wav
extention are added by record. Default is "record".
- -i dev
- mixer control. This should be the one where you can adjust the
record level for your audio source. Default is "line". "mic" and
"igain" are good candidates too. Best way to figure is to start
your favorite mixer tool and check out which one works ...
- -m dev
- set mixer device. Default is "/dev/mixer".
- -d dev
- set audio device. Default is "/dev/dsp".
- -r rate
- set sample rate. Default is 44100.
- -p sec
- peak seconds (number of seconds which should be scanned for the
volume maximum). This affects both peak level display and level
triggered recording (see below). Default is 1.5 seconds. record can
also be used non-interactive:
- -c
- enable console (non-interactive) mode.
- -v
- be verbose (console mode only).
- -t mm:ss
- Limit the record time (console mode only). By default record
records until stopped by a signal (by typing ^C for example).
- -s size
- Limit the file size (console mode only). record will continue
with a new file once the limit is reached.
- -n num
- Limit the file count (console mode only). record will stop
recording after num files.
- -l
- Enable level triggered recording (console mode only) with the
default trigger level (1000).
- -L level
- Enable level triggered recording with the specified trigger
level. If level triggered recording is active, record will start
and stop recording depending on the signal strength. Recording will
be started if the signal strength is above the trigger level
(1000/32768 => around 3%). Recording will be stopped if the
signal is below the trigger level for some time (1.5 seconds by
default, the -p switch changes this).
