ROTTER(1)
NAME
rotter - a recording of transmission / audio logger for JACK
SYNOPSIS
rotter [options] <directory>
DESCRIPTION
Rotter is a Recording of Transmission / Audio Logger for JACK. It was
designed for use by radio stations, who are legally required to keep a
recording of all their output. Rotter runs continuously, writing to a
new file every hour.
- Rotter can output files in two different strutures, either all files in
a single directory or create a directory structure:
- flat: /root_directory/YYYY-MM-DD-HH.suffix
hierarchy: /root_directory/YYYY/MM/DD/HH/archive.suffix
combo: /root_directory/YYYY/MM/DD/HH/YYYY-MM-DD-HH.suffix
dailydir: /root_directory/YYYY-MM-DD/YYYY-MM-DD-HH.suffix - The advantage of using a folder hierarchy is that you can store related files in the hour's directory.
OPTIONS
- -a
- Automatically connect JACK ports to the first two JACK input ports found.
- -f <format>
- Select the output format of the log files. See the rotter help
screen for a list of supported output format names. - -b <bitrate>
- Select the bitrate (in kbps) of the log file. This parameter is
only supported by bitstream formats (MPEG Audio). - -c <channels>
- Set the number of input channels to be logged. This number of JACK ports will be created. Should either 1 or 2.
- -n <name>
- Choose the name of the Jack client to register as.
- -N <filename>
- Choose a filename prefix for the archive files created (default
archive). - -d <hours>
- Specifies the number of hours of audio to keep before it is
deleted. Files are deleted at the start of every hour, based on the files modification date. Default is to not delete files. - -R <secs>
- Sets the length (in seconds) of the ringbuffer. This is the buffer
between the internal audio grabber and the audio encoder. If you
have a slow machine you might want to try increating the size of
the buffer. - -L <layout>
- Choose a file layout option for the archive files created. See
above for a list. - -j
- By default rotter will automatically try and start jackd if it
isn't running. This option disables that feature. - -v
- Enable verbose mode. Display more messages about what rotter is
doing. - -q
- Enable quiet mode. Only display error messages.
EXAMPLES
rotter -a -f mp3 -d 1000 -b 160 -v /var/achives
Start logging audio to hourly files in /var/archives. Rotter will
automatically connect itself to the first two JACK output ports it
finds and encode to MPEG Layer 3 audio at 128kbps. Each hour it will
delete files older than 1000 hours (42 days). Verbose mode means it
will display more informational messages.
