Scissor

Description

utility to chop sound files

supported file format:

rake install

gem sources -a gems.github.com/

gem install youpy-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’)

# 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’
