Chop audio

Cut, slice and reshape any audio file into new samples: find the hits, cut on them, stretch or pitch the result and load the slices on a sampler. Your original file is never changed.

✦Ask

• "slice the break into its hits and put them on a sampler"
• "cut bars 9 to 13 of the song and pitch it down 3"
• "find the other places that sound like the hook"
