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

== Synopsis

=== instantiate

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

 foo + bar > 'foobar.mp3'

=== slice + concat

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

=== slice + concat + loop

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

=== split

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

=== replace first 10 seconds with 30 seconds of silence

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

=== sequence + loop

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

=== half the pitch

 foo.pitch(50)

=== 200% time stretch without changing the pitch

 foo.stretch(200)

=== mix

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