• 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.
