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
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).
