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.
