Frequently asked questions

How do I make a slowed + reverb version of a song?

Drop the track in, pull the speed down to roughly 0.75 to 0.85, pick a reverb type, then export. Most of the sound comes from those two moves. From there the parametric reverb EQ is what separates a clean edit from a muddy one.

Why does the song sound lower when I slow it down?

Because slowing audio stretches its waveform, which drops the pitch with it, exactly like playing a record at a lower speed. That coupling is the slowed aesthetic, not a bug. If you want the slower tempo without the darker pitch, raise the pitch control back up separately.

How do I make a nightcore edit instead?

Push the speed above 1.0, usually somewhere around 1.25, and the pitch rises with it. That's the whole nightcore effect. Add little or no reverb, since nightcore wants the opposite of the washed-out slowed sound.

What does the reverb EQ actually change?

It shapes the reverb tail rather than the song. Drag the bands to cut low mud out of a big hall, or roll off the top so the tail sits behind the vocal instead of hissing over it. There are five reverb types to start from, and the EQ is what makes each one usable on a specific track.
