"description": "exp - For each sample, the value is compared to the previous sample. If it is greater than the previous, the value of the envelope is equal to the value of that sample, and that sample is stored as the current peak. If it is less than, the value of the envelope decays exponentially from the last peak to the current value (as more samples pass that are smaller than the peak, the envelope decays toward the waveform). Pros: Always encloses the data. Cons: Slope can be discontinuous, making the output look bumpy. window - The channel is separated into windows of N samples determined by the Envelope Width. In each window, the maximum amplitude (or power) is found. The maximum value of the window is placed as a data point in the center of the window, and these points are cubically interpolated together to form the output envelope. Pros: Produces Good shapes. Cons: Signal sometimes jumps outside the envelope. The signal is quantized, so pulses can be off by as much as N/2.",
