What Is Slowed + Reverb?
Slowed + Reverb (also searched as slowed reverb, slowed and reverb, or slowed + reverb converter) is an audio style that lowers pitch, slows tempo, and adds echo so a song feels dreamy and atmospheric. It is popular for late-night listening, study playlists, and TikTok or YouTube edits. Our Slowed + Reverb converter applies that mix automatically so you do not need Audacity, BandLab, or a DAW.
What Is Nightcore?
Nightcore speeds a track up and raises the pitch for a brighter, more energetic sound — the opposite of slowed reverb. A nightcore converter (or nightcore maker) is used for remixes, anime-style edits, and workout playlists. MP3Extra creates nightcore MP3s from YouTube in one click, plus a Super Nightcore option for even more speed and pitch.

Slowed + Reverb & Nightcore FAQ
Is this Slowed + Reverb converter free?
Yes. You can create Slowed + Reverb, Nightcore, 8D audio, bass boosted, and vaporwave MP3s from YouTube for free. There is no subscription and no app to install.
How do I make Slowed + Reverb from a YouTube song?
Paste the YouTube URL, wait for the track to load, select Slowed + Reverb (or Super Slowed), adjust the Speed and Reverb sliders if you want, then click Download. The MP3 is processed on the server and saved to your device.
How do I make Nightcore from YouTube?
Paste the YouTube link, choose Nightcore or Super Nightcore, and download the MP3. Nightcore raises pitch and speeds the song up; Super Nightcore is even faster.
What is the difference between Slowed + Reverb and Nightcore?
Slowed + Reverb lowers pitch, slows the song, and adds echo. Nightcore does the opposite: higher pitch and faster tempo, usually without heavy reverb. Both are remix-style listening effects, not the original mix.
Do I need headphones for 8D audio?
8D audio is designed for headphones so you can hear the stereo rotation. It still plays on speakers, but the 8D effect is much clearer with headphones.
Can I use this on iPhone or Android?
Yes. Open mp3extra.com/slowed-reverb in Safari or Chrome, paste the YouTube link, pick an effect, and download. No app is required.
Is Slowed + Reverb or Nightcore the original song?
No. These are processed versions (pitch, speed, echo, or stereo effects). Use them for personal listening. Respect copyright and the rights of artists and labels.
Why is there a time limit for effects?
Audio effects are heavier to process than a plain MP3 download. Tracks up to 30 minutes are supported — enough for songs, covers, and most mixes. For longer videos, download regular MP3 from the YouTube to MP3 page.
