What is Rotter ?
----------------
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.
Usage
-----
rotter [options] <root_directory>
-a Automatically connect JACK ports
-f <format> Format of recording (see list below)
-b <bitrate> Bitrate of recording (bitstream formats only)
-c <channels> Number of channels
-n <name> Name for this JACK client
-N <filename> Name for archive files (default 'archive')
-d <hours> Delete files in directory older than this
-R <secs> Length of the ring buffer (in seconds)
-L <layout> File layout (default 'hierarchy')
-j Don't automatically start jackd
-v Enable verbose mode
-q Enable quiet mode

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.
