How to Make Slowed & Reverb Songs (Step-by-Step Guide)

What Is Slowed & Reverb Music?

Slowed and reverb is a music remix technique where you take an existing song, reduce its playback speed (usually to 0.75×–0.9×), and layer a reverb effect on top. The result is a dreamy, ethereal version of the original that feels like listening to music underwater or in a vast empty hall.

The technique evolved from DJ Screw's "chopped and screwed" style that originated in 1990s Houston hip-hop. While chopped and screwed involved rearranging and scratching vinyl, the modern slowed and reverb approach is simpler — it preserves the original song structure and adds spatial reverb for atmosphere.

Today, slowed and reverb is everywhere: YouTube compilations, TikTok edits, Spotify study playlists, and SoundCloud mixes. The genre has hundreds of millions of streams across platforms, making it one of the most accessible ways to remix music.

Why People Create Slowed & Reverb Songs

The appeal of slowed and reverb goes beyond just a cool audio effect. Here's why millions of people create and listen to these remixes:

• Emotional depth — Slowing a song down reveals details in the vocals and instrumentation that you miss at normal speed. The added reverb creates a sense of space and intimacy.
• Study and focus music — The slower tempo and ambient reverb make slowed versions ideal for background listening during study or work sessions.
• Content creation — TikTok and YouTube creators use slowed and reverb edits as background audio for aesthetic videos, transitions, and cinematic montages.
• Creative expression— For bedroom producers and remix artists, slowed and reverb is a gateway into audio production. It's simple enough for beginners but expressive enough to create something genuinely beautiful.
• Nostalgia and mood — The dreamy quality of slowed reverb music evokes nostalgia, making familiar songs feel like distant memories.

How to Make Slowed & Reverb in Audacity (Free Method)

Audacity is a free, open-source audio editor available on Windows, Mac, and Linux. Here's how to create slowed and reverb manually:

Step 1: Import Your Audio

Open Audacity and go to File → Import → Audio. Select the MP3, WAV, or FLAC file you want to remix. Your track will appear as a waveform in the main editor.

Step 2: Slow Down the Track

Select the entire track (Ctrl+A / Cmd+A), then go to Effect → Change Speed. Set the speed reduction to around -15% (for 0.85× playback) or -25% (for 0.75× playback). Click "Apply."

Important:Use "Change Speed" (not "Change Tempo"). Change Speed lowers both tempo and pitch simultaneously, which is essential for the authentic slowed and reverb sound. Change Tempo preserves pitch, which defeats the purpose.

Step 3: Apply Reverb

With the track still selected, go to Effect → Reverb. Start with these settings:

• Room Size: 75–85%
• Reverb: 40–60%
• Damping: 50%
• Wet Gain: -1 dB to -3 dB
• Dry Gain: 0 dB
• Stereo Width: 100%

Click "Preview" to test, then "OK" to apply. If the reverb sounds too washed out, reduce the Room Size or increase the Damping.

Step 4: Optional — Add Bass Boost

For a warmer, deeper sound, go to Effect → Bass and Treble. Increase bass by +3 to +6 dB. Be careful not to overdo it — too much bass creates muddy audio.

Step 5: Export

Go to File → Export → Export as MP3 (or WAV for lossless quality). Name your file, choose your bitrate (320kbps recommended for MP3), and save.

How to Make Slowed & Reverb in FL Studio or Other DAWs

If you use FL Studio, Ableton Live, Logic Pro, or another DAW, the process is similar but gives you more control over the final result.

FL Studio Method

1. Import your audio — Drag your audio file into the Playlist or Channel Rack.
2. Set the project tempo— Lower the BPM to about 85% of the original. If the original song is 120 BPM, set your project to ~102 BPM. Make sure "Stretch" mode is set to Resample (not e3 or e2), so pitch drops with tempo.
3. Add reverb — Open the Mixer, add Fruity Reeverb 2or Convolver to an insert channel. Set the wet/dry mix to about 40–60%, decay time to 3–5 seconds, and room size to large.
4. Optional: Bass boost — Add Fruity Parametric EQ 2. Boost the 80–150 Hz range by +3 to +5 dB for warmer bass.
5. Export — Go to File → Export → WAV or MP3.

Ableton Live Method

1. Import audio into an Audio Track.
2. In the clip settings, switch Warp Mode to Re-Pitch (this links pitch to tempo, essential for slowed and reverb).
3. Lower the master tempo to 85% of original (e.g., 120 BPM → 102 BPM).
4. Add a Reverb effect from Audio Effects. Set Decay to 4–6s, Dry/Wet to 40–60%.
5. Export via File → Export Audio/Video.

Logic Pro Method

1. Import your audio file to a track.
2. Select the region, open the Region Inspector, and enable Flex & Follow → Speed. Lower the project tempo.
3. Add Space Designer or ChromaVerb for reverb. Use a large hall preset as a starting point.
4. Export via File → Bounce → Project.

Common Mistakes When Making Slowed & Reverb

Even though the technique is simple, beginners often make these errors:

1. Using "Change Tempo" instead of "Change Speed"— Change Tempo preserves pitch, so you get slower music without the pitch drop. That's not slowed and reverb — that's just slow music. Always use Change Speed (or Resample mode in your DAW) to lower pitch along with tempo.
2. Too much reverb — Cranking reverb to 100% makes the audio muddy and unintelligible. Start at 40–50% and increase gradually. The vocals should still be clearly audible.
3. Ignoring bass balance— Slowing down a track boosts low frequencies naturally. Adding too much bass boost on top creates a boomy, distorted sound. Use +3 dB bass boost maximum unless you're going for an exaggerated effect.
4. Not normalizing before export— Slowing and adding reverb can reduce overall volume. Normalize your audio to -1 dB before exporting to ensure it's loud enough for listeners.
5. Exporting at low quality— If you're exporting as MP3, use 320kbps. Reverb effects have a lot of subtle high-frequency detail that gets destroyed at lower bitrates like 128kbps.

The Faster Way: Use an Online Slowed & Reverb Generator

The Audacity and DAW methods above work great, but they require installing software, learning the interface, and spending 15–30 minutes per track. If you want to create slowed and reverb music quickly — especially for social media or personal listening — an online tool is significantly faster.

SonicLab's free slowed and reverb generator lets you upload any song, adjust speed, reverb depth, pitch, and bass with real-time preview, and download in seconds. No account required, no software to install, and it works on any device.

Instead of configuring effect chains and rendering offline, you can create slowed and reverb music online with a few slider adjustments. Built-in presets like Classic, Dreamy, Lo-fi, and Vapor give you instant starting points that you can fine-tune to taste.
