How to Make Slowed + Reverb Remixes Online — Free Generator
Learn how to make slowed + reverb (daycore) remixes online for free. Adjust speed, pitch, reverb intensity, room simulation, and bass boost — no download needed.
What Is Slowed + Reverb?
Slowed + reverb is a music remixing style where a song is slowed down and reverb (echo) is added, creating a dreamy, atmospheric, lo-fi sound. It’s also called daycore — the opposite of nightcore, which speeds songs up.
The genre exploded on YouTube and TikTok in the early 2020s. Channels like “slowed + reverb” uploads routinely hit millions of views. The appeal is simple: familiar songs sound completely different when stretched out with heavy echo — more emotional, more atmospheric, almost underwater.

Understanding the Controls
Speed & Pitch
The two most important sliders:
| Setting | What It Does | Classic Value |
|---|---|---|
| Tempo | How much to slow down the song | 0.8x (20% slower) |
| Pitch | How much to lower/raise the tone | 0.8x (deeper voice) |
In classic slowed + reverb, both are set to 0.8x — the song plays 20% slower with a proportionally deeper pitch. For a more subtle vibe, try 0.85x. For a deeply atmospheric sound, go down to 0.7x.
Reverb
Reverb is the echo effect that gives slowed + reverb its signature spacious sound. Our generator offers two ways to control it:
Reverb slider (0-100%) — controls echo intensity. 0% = dry (no echo), 60% = classic slowed + reverb, 100% = heavy underwater effect.
Room simulation — simulates real acoustic spaces:
- Small Room — tight, intimate echo (good for vocals)
- Large Hall — wide, spacious reverb (concert hall feel)
- Cathedral — massive, ethereal echo with long decay (the dreamiest option)
Bass Boost
Bass boost amplifies the low-end frequencies for a deeper, richer sound:
- Light — subtle warmth
- Medium — noticeable thump, good for hip-hop and R&B
- Heavy — club-like bass, very prominent

Slowed + Reverb vs Daycore vs Nightcore
| Style | Speed | Pitch | Reverb | Vibe |
|---|---|---|---|---|
| Slowed + Reverb | 0.7x–0.85x | Lower | Heavy | Dreamy, atmospheric |
| Daycore | Same as above | Same | Same | Same thing, different name |
| Nightcore | 1.2x–1.5x | Higher | None | Energetic, anime-style |
Daycore and slowed + reverb are the same thing. “Slowed + reverb” describes the technique; “daycore” is the genre name (contrasting with nightcore). Our Daycore tool and Slowed + Reverb tool are identical — use whichever name you prefer.

Tips for the Best Slowed + Reverb Sound
1. Start with a Good Source
Songs with strong vocals and clean production work best. Lo-fi or heavily compressed audio tends to sound muddy when slowed further. Use the highest quality source file you can find (WAV or 320kbps MP3).
2. Don’t Over-Slow
Going below 0.7x makes most songs sound distorted and unnatural. The sweet spot for most genres is 0.75x–0.85x. Some songs sound amazing at 0.9x (barely slowed) with heavy reverb.
3. Match Reverb to the Song
- Ballads and R&B — high reverb (70-90%) with Cathedral room
- Hip-hop and Rap — medium reverb (40-60%) with bass boost on medium
- Pop — moderate reverb (50-70%) with Large Hall room
- Lo-fi beats — they’re already slow, so use light reverb (20-40%) and minimal speed change
4. Use Bass Boost Sparingly
Bass boost sounds great on tracks with strong sub-bass, but it can make muddy tracks worse. Start with Light, listen, then increase if the track can handle it.
Best Speed Settings by Genre
| Genre | Recommended Tempo | Recommended Pitch | Notes |
|---|---|---|---|
| R&B / Soul | 0.8x | 0.8x | Classic daycore territory |
| Hip-Hop | 0.82x | 0.85x | Keep it close to original groove |
| Pop | 0.78x | 0.78x | Can go slower than most genres |
| Rock / Alt | 0.85x | 0.82x | Subtle slowdown works best |
| EDM | 0.75x | 0.8x | Transforms energy into atmosphere |
| Classical | 0.9x | 0.9x | Barely slow — just add reverb |
