Filter: noop derivative integral subtract-overlap isolate-overlap mono

• noop

  Leaves the audio unchanged.

• derivative

  Approximates the first derivative of the audio as a function respect to time. Sounds like a high-pass filter.

• integral

  Approximates the first integral of the audio as a function respect to time. Plus C of zero. Sounds like a low-pass filter.

• subtract-overlap

  Inverts the amplitude of every even-numbered channel and merges all channels to mono. This effectively cancels the sounds the left and right channels share in common. Quick-and-dirty way of removing vocals.

• isolate-overlap

  The opposite of subtract-overlap. You think it'd be simple but I can't get it to work :/

• mono

  Converts the audio to mono by taking the arithmetic average of the samples of each channel.
