* http://github.com/alban.peignier/alsa-backup
== DESCRIPTION:
ALSA client to perform continuous recording
== FEATURES/PROBLEMS:
* configurable file name strategy
== SYNOPSIS:
By using the default settings :
alsa-backup
will record in record.wav the default alsa device
By using command line arguments :
alsa-backup --directory=/tmp --file=test.wav --length=2
will record 2 seconds in /tmp/test.wav
By loading a configuration :
alsa-backup --config=/path/to/config
will load the specified configuration
== CONFIGURATION:
The configuration file is a Ruby file. This piece of code can
configurate the AlsaBacup recorder :
AlsaBackup.config do |recorder|
# configure recorder here :
recorder.file = "record.wav"
end
=== Recorder File
The recorder file can be specified as a simple string :
recorder.file = "record.wav"
The recorder file can be specified by a Proc which returns the string :
recorder.file = Proc.new {
Time.now.strftime("%Y/%m-%b/%d-%a/%Hh.wav")
}
will use the current time to create file names like these :
2009/05-May/17-Sun/19h.wav
2009/05-May/17-Sun/20h.wav
To use different files every 15 minutes :
recorder.file = Proc.new {
Time.now.floor(:min, 15).strftime("%Y/%m-%b/%d-%a/%Hh%M.wav")
}
will create files like these :
2009/05-May/17-Sun/19h00.wav
2009/05-May/17-Sun/19h15.wav
See config.sample.
