The Part Effects Editor applies slowed, reverb, nightcore, bass boost, 8D, and lo-fi effects to a single section of a song instead of the whole track. It is perfect for a slowed and reverb chorus, a nightcore drop, an 8D intro, or a bass-boosted beat drop, while the rest of the song plays normally. All the effects you choose are rendered together in one pass, and the edited part is blended back into the song with smooth transitions.
Drag on the waveform or type exact start and end times to choose the part to change.
Combine speed and pitch, reverb, bass boost, volume, 8D, and lo-fi in one render.
