• 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 :/

• bit-crusher-sr8

  Bitcrusher. Works by taking the average of 8 samples of the input and setting that average as the output for those 8 samples, effectively reducing the sampling rate.

• bit-crusher-res

  Bitcrusher. Works by reducing the resolution of each sample from a 32-bit float to a 8-bit float.

• bit-crusher-both

  Bitcrusher. Combines the output of bit-crusher-sr8 and bit-crusher-res.

• mono

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

• zeroes

  Outputs no sound.
