The document discusses various frequency and pitch control options in an audio editing program. The threshold option causes disturbance while options below the ratio modify existing effects. The amount setting determines how much an effect takes place while the seed makes audio sound echoey or robotic. The de-click and step envelope adjust echo effects and audio steps. The master filter, output, and overdrive options control frequency, volume, quality and mixing levels. Effects only take place when a method is applied to the audio.
