1. What You Need to Start
You need only two things: an audio file (MP3, WAV, FLAC, or OGG) and a browser. Open the slowed reverb generator — no account, no download, no sign-up required.
The entire process takes about 2 minutes: upload, adjust, preview, export. All processing happens locally in your browser, so your files stay private.
2. Step-by-Step: Make Your First Slowed Reverb Edit
Follow these steps for a clean slowed reverb song every time.
- Step 1: Open slowedreverbmaker.net in Safari, Chrome, or Firefox.
- Step 2: Click the upload area or drag and drop an MP3, WAV, FLAC, or OGG file.
- Step 3: Click the "Slowed + Reverb" preset chip. This sets speed to 0.80x, reverb to 70%, decay to 4s.
- Step 4: Fine-tune: adjust speed to 0.82x–0.88x, reverb wet to 35–45%, decay to 2.5–3.5s.
- Step 5: Add +1 semitone pitch if vocals are too dark, +2 to +4 dB bass for warmth.
- Step 6: Preview the chorus — the loudest section reveals clipping or muddiness.
- Step 7: Click Download, choose MP3 (smaller, shareable) or WAV (higher quality).
3. Recommended Presets for Different Genres
Use these presets as starting points. Adjust after previewing the first chorus.

4. Export Settings: MP3 vs WAV
MP3 at 320kbps: excellent quality (96% of listeners cannot distinguish from WAV), ~7MB for 3 minutes. Best for sharing, social media, and everyday listening.
WAV 16-bit: lossless, full quality, ~30MB for 3 minutes. Best for archival and further editing in other software.
For TikTok and Instagram, use MP3 at 320kbps. For YouTube, either format works. For further production, always export WAV.
5. Tips for Better Results
Use the highest quality source file you have — WAV or 320kbps MP3. Low-bitrate MP3s reveal artifacts after slowing.
Preview with headphones, not laptop speakers. What sounds clean on internal speakers may reveal issues on good headphones.
Make one change at a time. Adjust speed, listen. Adjust reverb, listen. Adjust bass, listen. Layering changes without previewing leads to muddy edits.
Compare with the original often. The toggle between "Original" and "Edited" mode helps catch over-processing.
