Nightcore reverse and daycore maker

Create a slower, lower-pitched daycore mix

This Nightcore Reverse tool creates a relaxed daycore-style version of a recording. It starts at 75% speed and lowers pitch along with speed. Notes last longer and voices sound deeper, giving the track a heavier feel.

Adjust speed to choose the pace, then select linked, preserved or custom pitch. The recording keeps its original sequence: this effect slows the track and does not reverse playback.

Nightcore Reverse means a slower, lower-pitched version here. It does not play the recording backwards. The default links pitch to speed.

Privacy and sound quality

Your recording stays on your device. Effects run locally in WebAssembly. Effects regenerate automatically after settings change. The preview and download share the same processed audio. The soft limiter protects against digital clipping.

Time stretching can introduce artifacts, especially at extreme settings. Processing long recordings needs more memory; start with a short clip on mobile.

Frequently asked questions

Does Nightcore Reverse play audio backwards?

No. Here, Nightcore Reverse means daycore: slower playback with a lower pitch. The preset uses 75% speed and linked pitch; it does not reverse the order of audio samples.

Can I slow the audio without lowering the voice?

Yes. Choose Keep original pitch in the pitch mode control; the effect regenerates automatically. Time stretching preserves the register while changing duration, although extreme settings may introduce artifacts.
