record - records *.wav files
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.)
- -h
- display help text
- -o file
- basename for the output file(s), a number and the .wav extension 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).
