AudioMonster

AudioMonster manipulates and transcodes audio. It wraps a number of different command line binaries such as sox, lame, twolame, and ffmpeg.

The following binary tools are required. They are available via most OS package managers.

For OS X use homebrew:

brew install lame
brew install sox
brew install twolame --frontend
brew install mp3val
brew install ffmpeg

For Redhat/CentOS use yum:

NOTE that some multimedia RPMs are available only via particular repositories. See e.g. http://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS7

yum install lame
yum install sox
yum install twolame
yum install mp3val
yum install ffmpeg
yum install libsndfile-devel libsndfile-utils

Add this line to your application's Gemfile:

gem 'audio_monster'

And then execute:

$ bundle

Or install it yourself as:

$ gem install audio_monster

AudioMonster can be configured to use a specific tempfile directory. It can also be configured to use a binary directory, or you can configure each binary. It will default to logging to STDOUT, or a logger can be configured.

For convenience, all methods can be called from the AudioMonster module.

The monster_test.rb contains examples of method calls.

To print potential expect checks, I sometimes change AudioMonster:

def self.method_missing(method, *args, &block)
  r = monster.send(method, *args)
  puts "audio_monster.expect(:#{method}, #{r}, #{args.map { |a| a.class.name }})"
  r
end
