A Ruby wrapper for the
sox command line tool to process sound.
- Bash (for process substitution combiner strategy)
- Chromaprint (only to run tests)
Debian / Ubuntu
apt-get install libsox-fmt-all sox libchromaprint-dev
# One of the following # Notes: # * chromaprint is not available in MacPorts as of this writing # * flac must be installed before sox so it will link during compilation sudo port install flac sox && brew install chromaprint brew install flac sox chromaprint
Remember that it's a wrapper for
sox to provide Ruby API.
It's assumed that you know the basics of sound computing theory and how
sox tool works. Otherwise,
man sox is your good friend.
Allows you to do everything that the
sox command does.
Mix 3 files into one (ruby-sox assumes that input files have same rate and number of channels):
# Build command sox = Sox::Cmd.new(:combine => :mix) .add_input("guitar1.flac") .add_input("guitar2.flac") .add_input("drums.flac") .set_output("hell_rock-n-roll.mp3") .set_effects(:rate => 44100, :channels => 2) # Execute command sox.run
Sox::Combiner combines files even if they have different rates or numbers of channels. Under the hood, it converts the input files into temporary files to have the same rate and number of channels, and then combines them.
combiner = Sox::Combiner.new(['in1.mp3', 'in2.ogg', 'in3.wav'], :combine => :concatenate) combiner.write('out.mp3')
Mix 3 files into an MP3 with 2 channels and a rate of 1600:
combiner = Sox::Combiner.new(['in1.mp3', 'in2.ogg', 'in3.wav'], :combine => :mix, :rate => 1600, :channels => 2) combiner.write('out.mp3')
