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.
