utility to chop sound files

supported file format:

• mp3

• wav

• m4a

• FFmpeg

• Ecasound 2.5.0 or higher

• Rubber Band

rake install 

gem update --system gem install gemcutter gem tumble gem install scissor 

• When you concatenate two or more files, format(sample rate, bit rate, …) mismatch causes unexpected changes to output file.

foo = Scissor('foo.mp3') bar = Scissor('bar.wav') 

foo = Scissor('http://example.com/foo.mp3') bar = Scissor('http://example.org/bar.wav') 

foo + bar > 'foobar.mp3' 

foo[10, 1] + bar[2, 3] > 'slicefoobar.mp3' 

(foo[10, 1] + bar[2, 3]) * 4 > 'slicefoobarloop.mp3' 

(Scissor('sequence.mp3') / 16).first.to_file('split.mp3') 

foo.replace(0, 10, Scissor.silence(30)).to_file('replace.mp3') 

seq = Scissor.sequence('x y xyz', 0.2) seq.apply(:x => foo, :y => Proc.new { bar }, :z => foo.reverse) * 4 > 'sequence.wav' 

foo.pitch(50) 

foo.stretch(200) 

foo.pan(0) # left only foo.pan(50) # center(default) foo.pan(100) # right only 

Scissor.mix([foo, bar], 'mix.mp3')
